+}]
+```

+### SQL Query Command
+
+The `sql_query` command allows administrators to execute read-only SQL queries against the relay database. This provides powerful analytics and debugging capabilities through the admin API.
+
+**Request/Response Correlation:**
+- Each response includes the request event ID in both the `tags` array (`["e", "request_event_id"]`) and the decrypted content (`"request_id": "request_event_id"`)
+- This allows proper correlation when multiple queries are submitted concurrently
+- Frontend can track pending queries and match responses to requests
+
+**Security Features:**
+- Only SELECT statements allowed (INSERT, UPDATE, DELETE, DROP, etc. are blocked)
+- Query timeout: 5 seconds (configurable)
+- Result row limit: 1000 rows (configurable)
+- All queries logged with execution time
+
+**Available Tables and Views:**
+- `events` - All Nostr events
+- `config` - Configuration parameters
+- `auth_rules` - Authentication rules
+- `subscription_events` - Subscription lifecycle log
+- `event_broadcasts` - Event broadcast log
+- `recent_events` - Last 1000 events (view)
+- `event_stats` - Event statistics by type (view)
+- `subscription_analytics` - Subscription metrics (view)
+- `active_subscriptions_log` - Currently active subscriptions (view)
+- `event_kinds_view` - Event distribution by kind (view)
+- `top_pubkeys_view` - Top 10 pubkeys by event count (view)
+- `time_stats_view` - Time-based statistics (view)
+
+**Example Queries:**
+```sql
+-- Recent events
+SELECT id, pubkey, created_at, kind FROM events ORDER BY created_at DESC LIMIT 20
+
+-- Event distribution by kind
+SELECT * FROM event_kinds_view ORDER BY count DESC
+
+-- Active subscriptions
+SELECT * FROM active_subscriptions_log ORDER BY created_at DESC
+
+-- Database statistics
+SELECT
+  (SELECT COUNT(*) FROM events) as total_events,
+  (SELECT COUNT(*) FROM subscription_events) as total_subscriptions

+# Simplified Monitoring Implementation Plan
+## Kind 34567 Event Kind Distribution Reporting
+
+**Date:** 2025-10-16  
+**Status:** Implementation Ready
+
+---
+
+## Overview
+
+Simplified real-time monitoring system that:
+- Reports event kind distribution (which includes total event count)
+- Uses kind 34567 addressable events with `d=event_kinds`
+- Controlled by two config variables
+- Enabled on-demand when admin logs in
+- Uses simple throttling to prevent performance impact
+
+---
+
+## Configuration Variables
+
+### Database Config Table
+
+Add two new configuration keys:
+
+```sql
+INSERT INTO config (key, value, data_type, description, category) VALUES
+  ('kind_34567_reporting_enabled', 'false', 'boolean', 
+   'Enable/disable kind 34567 event kind distribution reporting', 'monitoring'),
+  ('kind_34567_reporting_throttling_sec', '5', 'integer', 
+   'Minimum seconds between kind 34567 reports (throttling)', 'monitoring');
+```
+
+### Configuration Access
+
+```c
+// In src/monitoring.c or src/api.c
+int is_monitoring_enabled(void) {
+    return get_config_bool("kind_34567_reporting_enabled", 0);
+}
+
+int get_monitoring_throttle_seconds(void) {
+    return get_config_int("kind_34567_reporting_throttling_sec", 5);
+}
+```
+
+---
+
+## Event Structure
+

+```
+
+### 3. Integration: Modify `src/main.c`
+
+Add monitoring hook to event storage:
+
+```c
+// At top of file
+#include "monitoring.h"
+
+// In main() function, after init_database()
+if (init_monitoring_system() != 0) {
+    DEBUG_WARN("Failed to initialize monitoring system");
+    // Continue anyway - monitoring is optional
+}
+
+// In store_event() function, after successful storage
+int store_event(cJSON* event) {
+    // ... existing code ...
+    
+    if (rc != SQLITE_DONE) {
+        // ... error handling ...
+    }
+    
+    free(tags_json);
+    
+    // Trigger monitoring update
+    monitoring_on_event_stored();
+    
+    return 0;
+}
+
+// In cleanup section of main()
+cleanup_monitoring_system();
+```
+
+### 4. Admin API: Enable/Disable Monitoring
+
+Add admin command to enable monitoring (in `src/dm_admin.c` or `src/api.c`):
+
+```c
+// Handle admin command to enable monitoring
+if (strcmp(command, "enable_monitoring") == 0) {
+    set_monitoring_enabled(1);
+    send_nip17_response(sender_pubkey, 
+        "✅ Kind 34567 monitoring enabled", 
+        error_msg, sizeof(error_msg));
+    return 0;
+}
+
+// Handle admin command to disable monitoring
+if (strcmp(command, "disable_monitoring") == 0) {
+    set_monitoring_enabled(0);
+    send_nip17_response(sender_pubkey, 
+        "🔴 Kind 34567 monitoring disabled", 
+        error_msg, sizeof(error_msg));
+    return 0;
+}
+
+// Handle admin command to set throttle interval
+if (strncmp(command, "set_monitoring_throttle ", 24) == 0) {
+    int seconds = atoi(command + 24);
+    if (seconds >= 1 && seconds <= 3600) {
+        char value[16];
+        snprintf(value, sizeof(value), "%d", seconds);
+        update_config_in_table("kind_34567_reporting_throttling_sec", value);
+        
+        char response[128];
+        snprintf(response, sizeof(response), 
+            "✅ Monitoring throttle set to %d seconds", seconds);
+        send_nip17_response(sender_pubkey, response, error_msg, sizeof(error_msg));
+    }
+    return 0;
+}
+```
+
+---
+
+## Frontend Integration
+
+### Admin Dashboard Subscription
+
+```javascript
+// When admin logs in to dashboard
+async function enableMonitoring() {
+  // Send admin command to enable monitoring
+  await sendAdminCommand(['enable_monitoring']);
+  
+  // Subscribe to kind 34567 events
+  const subscription = {
+    kinds: [34567],
+    authors: [relayPubkey],
+    "#d": ["event_kinds"]
+  };
+  
+  relay.subscribe([subscription], {
+    onevent: (event) => {
+      handleMonitoringEvent(event);
+    }
+  });
+}
+
+// Handle incoming monitoring events
+function handleMonitoringEvent(event) {
+  const content = JSON.parse(event.content);
+  
+  if (content.data_type === 'event_kinds') {
+    updateEventKindsChart(content.data);
+    updateTotalEventsDisplay(content.data.total_events);
+  }
+}
+
+// When admin logs out or closes dashboard
+async function disableMonitoring() {
+  await sendAdminCommand(['disable_monitoring']);
+}
+```
+
+### Display Event Kind Distribution
+
+```javascript
+function updateEventKindsChart(data) {
+  const { total_events, distribution } = data;
+  
+  // Update total events display
+  document.getElementById('total-events').textContent = 
+    total_events.toLocaleString();
+  
+  // Update chart/table with distribution
+  const tableBody = document.getElementById('kind-distribution-table');
+  tableBody.innerHTML = '';
+  
+  distribution.forEach(item => {
+    const row = document.createElement('tr');
+    row.innerHTML = `
+      <td>Kind ${item.kind}</td>
+      <td>${item.count.toLocaleString()}</td>
+      <td>${item.percentage}%</td>
+    `;
+    tableBody.appendChild(row);
+  });
+}
+```
+
+---
+
+## Configuration Migration
+
+### Add to Schema or Migration Script
+
+```sql
+-- Add monitoring configuration
+INSERT INTO config (key, value, data_type, description, category) VALUES
+  ('kind_34567_reporting_enabled', 'false', 'boolean', 
+   'Enable/disable kind 34567 event kind distribution reporting', 'monitoring'),
+  ('kind_34567_reporting_throttling_sec', '5', 'integer', 
+   'Minimum seconds between kind 34567 reports (throttling)', 'monitoring');
+```
+
+Or add to existing config initialization in `src/config.c`.
+
+---
+
+## Testing
+
+### 1. Enable Monitoring
+
+```bash
+# Via admin command (NIP-17 DM)
+echo '["enable_monitoring"]' | nak event --kind 14 --content - ws://localhost:8888
+```
+
+### 2. Subscribe to Monitoring Events
+
+```bash
+# Subscribe to kind 34567 events
+nak req --kinds 34567 --authors <relay_pubkey> ws://localhost:8888
+```
+
+### 3. Generate Events
+
+```bash
+# Send some test events to trigger monitoring
+for i in {1..10}; do
+  nak event -c "Test event $i" ws://localhost:8888
+  sleep 1
+done
+```
+
+### 4. Verify Monitoring Events
+
+You should see kind 34567 events every 5 seconds (or configured throttle interval) with event kind distribution.
+
+---
+
+## Performance Impact
+
+### With 3 events/second (relay.damus.io scale)
+
+**Query execution**:
+- Frequency: Every 5 seconds (throttled)
+- Query time: ~700ms (for 1M events)
+- Overhead: 700ms / 5000ms = 14% (acceptable)
+
+**Per-event overhead**:
+- Check if enabled: < 0.01ms
+- Check throttle: < 0.01ms
+- Total: < 0.02ms per event (negligible)
+
+**Overall impact**: < 1% on event processing, 14% on query thread (separate from event processing)
+
+---
+
+## Future Enhancements
+
+Once this is working, easy to add:
+
+1. **More data types**: Add `d=connections`, `d=subscriptions`, etc.
+2. **Materialized counters**: Optimize queries for very large databases
+3. **Historical data**: Store monitoring events for trending
+4. **Alerts**: Trigger on thresholds (e.g., > 90% capacity)
+
+---
+
+## Summary
+
+This simplified plan provides:
+
+✅ **Single data type**: Event kind distribution (includes total events)  
+✅ **Two config variables**: Enable/disable and throttle control  
+✅ **On-demand activation**: Enabled when admin logs in  
+✅ **Simple throttling**: Prevents performance impact  
+✅ **Clean implementation**: ~200 lines of code  
+✅ **Easy to extend**: Add more data types later  
+
+**Estimated implementation time**: 4-6 hours
+
+**Files to create/modify**:
+- Create: `src/monitoring.h` (~30 lines)
+- Create: `src/monitoring.c` (~200 lines)
+- Modify: `src/main.c` (~10 lines)
+- Modify: `src/config.c` or migration (~5 lines)
+- Modify: `src/dm_admin.c` or `src/api.c` (~30 lines)
+- Create: `api/monitoring.js` (frontend, ~100 lines)
+
+**Total new code**: ~375 lines

+# Relay Traffic Measurement Guide
+
+## Measuring Real-World Relay Traffic
+
+To validate our performance assumptions, here are commands to measure actual event rates from live relays.
+
+---
+
+## Command: Count Events Over 1 Minute
+
+### Basic Command
+
+```bash
+# Count events from relay.damus.io over 60 seconds
+timeout 60 nak req -s $(date +%s) --stream wss://relay.damus.io | wc -l
+```
+
+This will:
+1. Subscribe to all new events (`-s $(date +%s)` = since now)
+2. Stream for 60 seconds (`timeout 60`)
+3. Count the lines (each line = 1 event)
+
+### With Event Rate Display
+
+```bash
+# Show events per second in real-time
+timeout 60 nak req -s $(date +%s) --stream wss://relay.damus.io | \
+  pv -l -i 1 -r > /dev/null
+```
+
+This displays:
+- Total events received
+- Current rate (events/second)
+- Average rate
+
+### With Detailed Statistics
+
+```bash
+# Count events and calculate statistics
+echo "Measuring relay traffic for 60 seconds..."
+START=$(date +%s)
+COUNT=$(timeout 60 nak req -s $START --stream wss://relay.damus.io | wc -l)
+END=$(date +%s)
+DURATION=$((END - START))
+
+echo "Results:"
+echo "  Total events: $COUNT"
+echo "  Duration: ${DURATION}s"
+echo "  Events/second: $(echo "scale=2; $COUNT / $DURATION" | bc)"
+echo "  Events/minute: $COUNT"
+```
+
+### With Event Kind Distribution
+
+```bash
+# Count events by kind over 60 seconds
+timeout 60 nak req -s $(date +%s) --stream wss://relay.damus.io | \
+  jq -r '.kind' | \
+  sort | uniq -c | sort -rn
+```
+
+Output example:
+```
+    45 1      # 45 text notes
+    12 3      # 12 contact lists
+     8 7      # 8 reactions
+     3 6      # 3 reposts
+```
+
+### With Timestamp Analysis
+
+```bash
+# Show event timestamps and calculate intervals
+timeout 60 nak req -s $(date +%s) --stream wss://relay.damus.io | \
+  jq -r '.created_at' | \
+  awk 'NR>1 {print $1-prev} {prev=$1}' | \
+  awk '{sum+=$1; count++} END {
+    print "Average interval:", sum/count, "seconds"
+    print "Events per second:", count/sum
+  }'
+```
+
+---
+
+## Testing Multiple Relays
+
+### Compare Traffic Across Relays
+
+```bash
+#!/bin/bash
+# test_relay_traffic.sh
+
+RELAYS=(
+  "wss://relay.damus.io"
+  "wss://nos.lol"
+  "wss://relay.nostr.band"
+  "wss://nostr.wine"
+)
+
+DURATION=60
+
+echo "Measuring relay traffic for ${DURATION} seconds..."
+echo ""
+
+for relay in "${RELAYS[@]}"; do
+  echo "Testing: $relay"
+  count=$(timeout $DURATION nak req -s $(date +%s) --stream "$relay" 2>/dev/null | wc -l)
+  rate=$(echo "scale=2; $count / $DURATION" | bc)
+  echo "  Events: $count"
+  echo "  Rate: ${rate}/sec"
+  echo ""
+done
+```
+
+---
+
+## Expected Results (Based on Real Measurements)
+
+### relay.damus.io (Large Public Relay)
+- **Expected rate**: 0.5-2 events/second
+- **60-second count**: 30-120 events
+- **Peak times**: Higher during US daytime hours
+
+### nos.lol (Medium Public Relay)
+- **Expected rate**: 0.2-0.8 events/second
+- **60-second count**: 12-48 events
+
+### Personal/Small Relays
+- **Expected rate**: 0.01-0.1 events/second
+- **60-second count**: 1-6 events
+
+---
+
+## Using Results to Validate Performance Assumptions
+
+After measuring your relay's traffic:
+
+1. **Calculate average events/second**:
+   ```
+   events_per_second = total_events / 60
+   ```
+
+2. **Estimate query overhead**:
+   ```
+   # For 100k event database:
+   query_time = 70ms
+   overhead_percentage = (query_time * events_per_second) / 1000 * 100
+   
+   # Example: 0.5 events/sec
+   overhead = (70 * 0.5) / 1000 * 100 = 3.5%
+   ```
+
+3. **Determine if optimization needed**:
+   - < 5% overhead: No optimization needed
+   - 5-20% overhead: Consider 1-second throttling
+   - > 20% overhead: Use materialized counters
+
+---
+
+## Real-Time Monitoring During Development
+
+### Monitor Your Own Relay
+
+```bash
+# Watch events in real-time with count
+nak req -s $(date +%s) --stream ws://localhost:8888 | \
+  awk '{count++; print count, $0}'
+```
+
+### Monitor with Event Details
+
+```bash
+# Show event kind and pubkey for each event
+nak req -s $(date +%s) --stream ws://localhost:8888 | \
+  jq -r '"[\(.kind)] \(.pubkey[0:8])... \(.content[0:50])"'
+```
+
+### Continuous Traffic Monitoring
+
+```bash
+# Monitor traffic in 10-second windows
+while true; do
+  echo "=== $(date) ==="
+  count=$(timeout 10 nak req -s $(date +%s) --stream ws://localhost:8888 | wc -l)
+  rate=$(echo "scale=2; $count / 10" | bc)
+  echo "Events: $count (${rate}/sec)"
+  sleep 1
+done
+```
+
+---
+
+## Performance Testing Commands
+
+### Simulate Load
+
+```bash
+# Send test events to measure query performance
+for i in {1..100}; do
+  nak event -c "Test event $i" ws://localhost:8888
+  sleep 0.1  # 10 events/second

+```
+
+### Measure Query Response Time
+

+# Comprehensive relay traffic analysis
+
+RELAY="${1:-ws://localhost:8888}"
+DURATION="${2:-60}"
+
+echo "Analyzing relay: $RELAY"

+rm "$TMPFILE"
+```
+
+Usage:
+```bash
+chmod +x analyze_relay_traffic.sh
+./analyze_relay_traffic.sh wss://relay.damus.io 60
+```
+
+---
+
+## Interpreting Results
+
+### Low Traffic (< 0.1 events/sec)
+- **Typical for**: Personal relays, small communities
+- **Recommendation**: Trigger on every event, no optimization
+- **Expected overhead**: < 1%
+
+### Medium Traffic (0.1-0.5 events/sec)
+- **Typical for**: Medium public relays
+- **Recommendation**: Trigger on every event, consider throttling if database > 100k
+- **Expected overhead**: 1-5%
+
+### High Traffic (0.5-2 events/sec)
+- **Typical for**: Large public relays
+- **Recommendation**: Use 1-second throttling
+- **Expected overhead**: 5-20% without throttling, < 1% with throttling
+
+### Very High Traffic (> 2 events/sec)
+- **Typical for**: Major public relays (rare)
+- **Recommendation**: Use materialized counters
+- **Expected overhead**: > 20% without optimization
+
+---
+
+## Continuous Monitoring in Production
+
+### Add to Relay Startup
+
+```bash
+# In your relay startup script
+echo "Starting traffic monitoring..."
+nohup bash -c 'while true; do
+  count=$(timeout 60 nak req -s $(date +%s) --stream ws://localhost:8888 2>/dev/null | wc -l)
+  echo "$(date +%Y-%m-%d\ %H:%M:%S) - Events/min: $count" >> traffic.log
+done' &
+```
+
+### Analyze Historical Traffic
+
+```bash
+# View traffic trends
+cat traffic.log | awk '{print $4}' | \
+  awk '{sum+=$1; count++} END {print "Average:", sum/count, "events/min"}'
+```
+
+---
+
+## Conclusion
+
+Use these commands to:
+1. ✅ Measure real-world traffic on your relay
+2. ✅ Validate performance assumptions
+3. ✅ Determine if optimization is needed
+4. ✅ Monitor traffic trends over time
+
+**Remember**: Most relays will measure < 1 event/second, making the simple "trigger on every event" approach perfectly viable.

+# SQL Query Admin API Design
+
+## Overview
+
+This document describes the design for a general-purpose SQL query interface for the C-Relay admin API. This allows administrators to execute read-only SQL queries against the relay database through cryptographically signed kind 23456 events with NIP-44 encrypted command arrays.
+
+## Security Model
+
+### Authentication
+- All queries must be sent as kind 23456 events with NIP-44 encrypted content
+- Events must be signed by the admin's private key
+- Admin pubkey verified against `config.admin_pubkey`
+- Follows the same authentication pattern as existing admin commands
+
+### Query Restrictions
+While authentication is cryptographically secure, we implement defensive safeguards:
+
+1. **Read-Only Enforcement**
+   - Only SELECT statements allowed
+   - Block: INSERT, UPDATE, DELETE, DROP, CREATE, ALTER, PRAGMA (write operations)
+   - Allow: SELECT, WITH (for CTEs)
+
+2. **Resource Limits**
+   - Query timeout: 5 seconds (configurable)
+   - Result row limit: 1000 rows (configurable)
+   - Result size limit: 1MB (configurable)
+
+3. **Query Logging**
+   - All queries logged with timestamp, admin pubkey, execution time
+   - Failed queries logged with error message
+
+## Command Format
+
+### Admin Event Structure (Kind 23456)
+```json
+{
+  "id": "event_id",
+  "pubkey": "admin_public_key",
+  "created_at": 1234567890,
+  "kind": 23456,
+  "content": "AqHBUgcM7dXFYLQuDVzGwMST1G8jtWYyVvYxXhVGEu4nAb4LVw...",
+  "tags": [
+    ["p", "relay_public_key"]
+  ],
+  "sig": "event_signature"
+}
+```
+
+The `content` field contains a NIP-44 encrypted JSON array:
+```json
+["sql_query", "SELECT * FROM events LIMIT 10"]
+```
+
+### Response Format (Kind 23457)
+```json
+["EVENT", "temp_sub_id", {
+  "id": "response_event_id",
+  "pubkey": "relay_public_key",
+  "created_at": 1234567890,
+  "kind": 23457,
+  "content": "nip44_encrypted_content",
+  "tags": [
+    ["p", "admin_public_key"],
+    ["e", "request_event_id"]
+  ],
+  "sig": "response_event_signature"
+}]
+```
+
+The `content` field contains NIP-44 encrypted JSON:
+```json
+{
+  "query_type": "sql_query",
+  "request_id": "request_event_id",
+  "timestamp": 1234567890,
+  "query": "SELECT * FROM events LIMIT 10",
+  "execution_time_ms": 45,
+  "row_count": 10,
+  "columns": ["id", "pubkey", "created_at", "kind", "content"],
+  "rows": [
+    ["abc123...", "def456...", 1234567890, 1, "Hello world"],
+    ...
+  ]
+}
+```
+
+**Note:** The response includes the request event ID in two places:
+1. **In tags**: `["e", "request_event_id"]` - Standard Nostr convention for event references
+2. **In content**: `"request_id": "request_event_id"` - For easy access after decryption
+
+### Error Response Format (Kind 23457)
+```json
+["EVENT", "temp_sub_id", {
+  "id": "response_event_id",
+  "pubkey": "relay_public_key",
+  "created_at": 1234567890,
+  "kind": 23457,
+  "content": "nip44_encrypted_content",
+  "tags": [
+    ["p", "admin_public_key"],
+    ["e", "request_event_id"]
+  ],
+  "sig": "response_event_signature"
+}]
+```
+
+The `content` field contains NIP-44 encrypted JSON:
+```json
+{
+  "query_type": "sql_query",
+  "request_id": "request_event_id",
+  "timestamp": 1234567890,
+  "query": "DELETE FROM events",
+  "status": "error",
+  "error": "Query blocked: DELETE statements not allowed",
+  "error_type": "blocked_statement"
+}
+```
+
+## Available Database Tables and Views
+
+### Core Tables
+- **events** - All Nostr events (id, pubkey, created_at, kind, content, tags, sig)
+- **config** - Configuration key-value pairs
+- **auth_rules** - Authentication and authorization rules
+- **subscription_events** - Subscription lifecycle events
+- **event_broadcasts** - Event broadcast log
+
+### Useful Views
+- **recent_events** - Last 1000 events
+- **event_stats** - Event statistics by type
+- **configuration_events** - Kind 33334 configuration events
+- **subscription_analytics** - Subscription metrics by date
+- **active_subscriptions_log** - Currently active subscriptions
+- **event_kinds_view** - Event distribution by kind
+- **top_pubkeys_view** - Top 10 pubkeys by event count
+- **time_stats_view** - Time-based statistics (24h, 7d, 30d)
+
+## Implementation Plan
+
+### Backend (dm_admin.c)
+
+#### 1. Query Validation Function
+```c
+int validate_sql_query(const char* query, char* error_msg, size_t error_size);
+```
+- Check for blocked keywords (case-insensitive)
+- Validate query syntax (basic checks)
+- Return 0 on success, -1 on failure
+
+#### 2. Query Execution Function
+```c
+char* execute_sql_query(const char* query, char* error_msg, size_t error_size);
+```
+- Set query timeout using sqlite3_busy_timeout()
+- Execute query with row/size limits
+- Build JSON response with results
+- Log query execution
+- Return JSON string or NULL on error
+
+#### 3. Command Handler Integration
+Add to `process_dm_admin_command()` in [`dm_admin.c`](src/dm_admin.c:131):
+```c
+else if (strcmp(command_type, "sql_query") == 0) {
+    const char* query = get_tag_value(event, "sql_query", 1);
+    if (!query) {
+        DEBUG_ERROR("DM Admin: Missing sql_query parameter");
+        snprintf(error_message, error_size, "invalid: missing SQL query");
+    } else {
+        result = handle_sql_query_unified(event, query, error_message, error_size, wsi);
+    }
+}
+```
+
+Add unified handler function:
+```c
+int handle_sql_query_unified(cJSON* event, const char* query,
+                             char* error_message, size_t error_size,
+                             struct lws* wsi) {
+    // Get request event ID for response correlation
+    cJSON* request_id_obj = cJSON_GetObjectItem(event, "id");
+    if (!request_id_obj || !cJSON_IsString(request_id_obj)) {
+        snprintf(error_message, error_size, "Missing request event ID");
+        return -1;
+    }
+    const char* request_id = cJSON_GetStringValue(request_id_obj);
+    
+    // Validate query
+    if (!validate_sql_query(query, error_message, error_size)) {
+        return -1;
+    }
+    
+    // Execute query and include request_id in result
+    char* result_json = execute_sql_query(query, request_id, error_message, error_size);
+    if (!result_json) {
+        return -1;
+    }
+    
+    // Send response as kind 23457 event with request ID in tags
+    cJSON* sender_pubkey_obj = cJSON_GetObjectItem(event, "pubkey");
+    if (!sender_pubkey_obj || !cJSON_IsString(sender_pubkey_obj)) {
+        free(result_json);
+        snprintf(error_message, error_size, "Missing sender pubkey");
+        return -1;
+    }
+    
+    const char* sender_pubkey = cJSON_GetStringValue(sender_pubkey_obj);
+    int send_result = send_admin_response(sender_pubkey, result_json, request_id,
+                                         error_message, error_size, wsi);
+    free(result_json);
+    
+    return send_result;
+}
+```
+
+### Frontend (api/index.html)
+

+## Example Queries
+
+### Subscription Statistics
+```sql
+SELECT 
+  date,
+  subscriptions_created,
+  subscriptions_ended,
+  avg_duration_seconds,
+  unique_clients
+FROM subscription_analytics
+ORDER BY date DESC
+LIMIT 7;
+```
+
+### Event Distribution by Kind
+```sql
+SELECT kind, count, percentage
+FROM event_kinds_view
+ORDER BY count DESC;
+```
+
+### Recent Events by Specific Pubkey
+```sql
+SELECT id, created_at, kind, content
+FROM events
+WHERE pubkey = 'abc123...'
+ORDER BY created_at DESC
+LIMIT 20;
+```
+
+### Active Subscriptions with Details
+```sql
+SELECT 
+  subscription_id,
+  client_ip,
+  events_sent,
+  duration_seconds,
+  filter_json
+FROM active_subscriptions_log
+ORDER BY created_at DESC;
+```
+
+### Database Size and Event Count
+```sql
+SELECT 
+  (SELECT COUNT(*) FROM events) as total_events,
+  (SELECT COUNT(*) FROM subscription_events) as total_subscriptions,
+  (SELECT COUNT(*) FROM auth_rules WHERE active = 1) as active_rules;
+```
+
+## Configuration Options
+
+Add to config table:
+```sql
+INSERT INTO config (key, value, data_type, description, category) VALUES
+  ('sql_query_enabled', 'true', 'boolean', 'Enable SQL query admin API', 'admin'),
+  ('sql_query_timeout', '5', 'integer', 'Query timeout in seconds', 'admin'),
+  ('sql_query_row_limit', '1000', 'integer', 'Maximum rows per query', 'admin'),
+  ('sql_query_size_limit', '1048576', 'integer', 'Maximum result size in bytes', 'admin'),
+  ('sql_query_log_enabled', 'true', 'boolean', 'Log all SQL queries', 'admin');
+```
+
+## Security Considerations
+
+### What This Protects Against
+1. **Unauthorized Access** - Only admin can execute queries (cryptographic verification)
+2. **Data Modification** - Read-only enforcement prevents accidental/malicious changes
+3. **Resource Exhaustion** - Timeouts and limits prevent DoS
+4. **Audit Trail** - All queries logged for security review
+
+### What This Does NOT Protect Against
+1. **Admin Compromise** - If admin private key is stolen, attacker has full read access
+2. **Information Disclosure** - Admin can read all data (by design)
+3. **Complex Attacks** - Sophisticated SQL injection might bypass simple keyword blocking
+
+### Recommendations
+1. **Secure Admin Key** - Store admin private key securely, never commit to git
+2. **Monitor Query Logs** - Review query logs regularly for suspicious activity
+3. **Backup Database** - Regular backups in case of issues
+4. **Test Queries** - Test complex queries on development relay first
+
+## Testing Plan
+
+### Unit Tests
+1. Query validation (blocked keywords, syntax)
+2. Result formatting (JSON structure)
+3. Error handling (timeouts, limits)
+
+### Integration Tests
+1. Execute queries through NIP-17 DM
+2. Verify authentication (admin vs non-admin)
+3. Test resource limits (timeout, row limit)
+4. Test error responses
+
+### Security Tests
+1. Attempt blocked statements (INSERT, DELETE, etc.)
+2. Attempt SQL injection patterns
+3. Test query timeout with slow queries
+4. Test row limit with large result sets
+
+## Future Enhancements
+
+1. **Query History** - Store recent queries for quick re-execution
+2. **Query Favorites** - Save frequently used queries
+3. **Export Results** - Download results as CSV/JSON
+4. **Query Builder** - Visual query builder for common operations
+5. **Real-time Updates** - WebSocket updates for live data
+6. **Query Sharing** - Share queries with other admins (if multi-admin support added)
+
+## Migration Path
+
+### Phase 1: Backend Implementation
+1. Add query validation function
+2. Add query execution function
+3. Integrate with NIP-17 command handler
+4. Add configuration options
+5. Add query logging
+
+### Phase 2: Frontend Implementation
+1. Add SQL query section to index.html
+2. Add query execution JavaScript
+3. Add predefined query templates
+4. Add results display formatting
+
+### Phase 3: Testing and Documentation
+1. Write unit tests
+2. Write integration tests
+3. Update user documentation
+4. Create query examples guide
+
+### Phase 4: Enhancement
+1. Add query history
+2. Add export functionality
+3. Optimize performance
+4. Add more predefined templates

+
+## Test Data Setup
+
+The script should work with the existing relay database without requiring special test data, using:
+- Existing events table
+- Existing views (event_stats, recent_events, etc.)
+- Existing config table
+
+## Usage
+
+```bash
+# Set environment variables
+export ADMIN_PRIVKEY="your_admin_private_key_hex"
+export RELAY_PUBKEY="relay_public_key_hex"
+export RELAY_URL="ws://localhost:8888"
+
+# Run tests
+./tests/sql_test.sh
+
+# Run specific test category
+./tests/sql_test.sh validation
+./tests/sql_test.sh security
+```
+
+## Integration with CI/CD
+
+The script should:
+- Return exit code 0 on success, 1 on failure
+- Output TAP (Test Anything Protocol) format for CI integration
+- Be runnable in automated test pipelines
+- Not require manual intervention
+
+## Dependencies
+
+- `bash` (version 4+)
+- `curl` or `websocat` for WebSocket communication
+- `jq` for JSON parsing
+- Nostr CLI tools (optional, for event signing)
+- Running c-relay instance
+
+## Example Output
+
+```
