x402 merchant
AttestationTimestampSha256ReceiptsVerification

Use when an agent needs to show later that a file, answer or record existed unchanged at a point in time: send its sha256, and get back a signed, timestamped receipt over it; a later altered copy no longer matches. Optional note; with an idempotency_key (x402 payments only), a retry gets the same receipt and is not a new record. For signed evidence of what a web page said at a given time (provenance), use /v1/fetch, whose receipt attests the page hashes. 5 free calls a day.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://preview.roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://preview.roundhouseai.io/skill.md first — it is the whole procedure.
