Bulk notarization: notarize up to 10 public URLs in ONE settled call, each returning its own tamper-evident ed25519 attestation with the bytes archived, exactly as the single snapshot endpoint does. Cheaper than five individual snapshots and one round trip instead of ten. Failures are reported per URL; the rest still return.

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. Alter one byte and verification fails. Anyone can verify it offline against the published key, free, forever.

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.

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.

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.

Final result for a single sporting fixture, shaped for prediction-market settlement: returns the completed score with a completion flag and, with attest=true, a notarized ed25519 attestation of the source page bundled in. Refuses (HTTP 409) to attest an event that is not final, so it can be wired straight into settlement logic. jurat is the evidence layer an oracle or dispute process cites, not a settlement oracle itself: it proves what the source reported, never that the source is right.

Change detection with proof attached: jurat monitors a URL by whole-body hash, a JSON field (json:<dot.path>), a regular expression (regex:<pattern>) or a sports fixture (result:<league>:<event_id>) on the cadence you set, then POSTs your webhook the moment the value changes, carrying the old value, the new value and a fresh ed25519 attestation of the source. Buy the watcher once instead of polling.

Schedule a wakeup: jurat holds your payload and POSTs it to your webhook at the time you name. A managed scheduler and cron for ephemeral, stateless agents that cannot stay alive between tasks, so work can resume without a process waiting.

Monitor EVERY fixture in a league for the day with one call: jurat webhooks each final result as it lands, with a signed source attestation attached, then closes itself when the slate completes. The bulk settlement product.

Recurring wakeups: jurat POSTs your payload to your webhook every N seconds from the first fire until expiry. A standing scheduler for ephemeral, stateless agents, rescheduling from now after downtime rather than firing a burst of missed slots.
