Dear HTTP Working Group and Dispatch participants, We have published an initial individual Internet-Draft specifying the X402 Typed Settlement Wire Protocol (X402-TSWP), an application-layer extension to Hypertext Transfer Protocol status code 402 (Payment Required). Document URL: https://datatracker.ietf.org/doc/draft-shabazz-http-x402-tswp/ HTMLized Version: https://datatracker.ietf.org/doc/html/draft-shabazz-http-x402-tswp Abstract: This document specifies machine-to-machine challenge-response headers, deterministic payment fulfillment schemas, and structured error responses for HTTP 402. It introduces a typed operational grammar (X402<Type>:<Payload>) that eliminates fragile regex parsing by utilizing byte-exact token preimages verifiable natively across parallel distributed ledgers (such as Solana and the XRP Ledger) and off-chain execution environments. We welcome feedback, review, and comments from the Working Group regarding the header definitions, security considerations, and alignment with RFC 9110. Best regards, Abdul Shabazz Synaptics Lab veritasvaultone@gmail.com
