Authorizations

​
Payment-Signature
string
header
required

Base64-encoded signed payment payload as defined by the x402 protocol. Omit on the first attempt to receive the 402 challenge in the PAYMENT-REQUIRED response header; include it on the retry to settle payment and receive the resource.

The legacy header name X-PAYMENT is also accepted by the server for backward compatibility — clients may send either, but Payment-Signature is preferred.

See x402.org for the on-the-wire shape of the PaymentRequired challenge and the settlement receipt returned in the PAYMENT-RESPONSE response header.
