jurat.dev

Audit any x402 endpoint before you pay it: reads the live HTTP 402 challenge, decodes the payment terms, and compares the price advertised in its openapi.json against the price actually charged. Returns a compliance verdict, a safe-to-pay signal and a per-check fix list. Catches silent price drift, unpayable challenges, and the misconfigurations that make discovery indexes drop a resource.

Create a change watcher: jurat checks a URL (hash / json:<path> / regex:<pattern>) or a sports event (result:<league>:<event_id>) on your cadence and POSTs your webhook on change or final whistle, with a signed source attestation attached.

Notarize any public web page or API response: fetches the URL server-side, archives the exact bytes, and returns a tamper-evident ed25519 attestation recording the final URL, UTC timestamp, HTTP status, content type, byte length and sha256 hash. Establishes provenance and a chain of custody for what a source said at a point in time, so the signed record can serve as the evidence layer in a later dispute or audit trail.

Single-event FINAL result for market settlement, optionally bundled with a notarized snapshot of the source (attest=true). Refuses to attest non-final events.

Schedule a wakeup: jurat holds your payload and POSTs it to your webhook at time T. Cron for agents that cannot stay alive.

Normalized scoreboard of fixtures across 24 leagues (US majors, top soccer leagues, the South African Premiership, UFC, 8 rugby competitions, IPL and Big Bash cricket): every fixture with its state, completion flag and score, from one call.

Signed conformance report over a whole x402 service. Sweeps every paid endpoint the service declares, GET and POST alike, runs the same checks /v1/preflight runs on each, grades the result, and returns an ed25519-signed report the operator can publish and anyone can verify offline. Coverage is inside the signature, so a partial sweep can never be passed off as a full one. Retrieving any report is free forever.
