 ### Unpaid Uploads
 
-Some servers `MAY` accept unpaid uploads and require payment after the upload is completed. In this case, the server `MUST` return a **402 Payment Required** status code along with a `Www-Authenticate` header containing the macaroon and payment request fields using the [L402 protocol](https://github.com/lightninglabs/L402) for the endpoints described in [#payment-required](#payment-required).

 For backward compatibility, the server `SHOULD` display a QR code, JSON file, or other useful information instead of the blob in the response body. When the payment is completed, the server `MUST` replace this information with the actual uploaded file.
