jurat docs
Evidence infrastructure for AI agents: notarized URL snapshots single and in bulk, daily merkle anchoring, change watchers, agent wakeups, sports settlement with proof, and x402 pre-flight and conformance auditing. Paid per call in USDC on Base via x402. Everything below is reference; everything machine-readable is at /catalog and /openapi.json.
Notarized URL snapshots and offline verification
How jurat attestations work: signed, timestamped records of exactly what a URL returned, with archived bytes, ed25519 signatures and free offline verification.
Bulk notarization: up to 10 URLs in one settled call
Notarize up to 10 public URLs in a single x402 payment, each returning its own signed attestation, with per-URL failures reported instead of failing the batch.
Daily merkle anchoring of attestations
How jurat rolls every attestation into a daily signed merkle root and anchors it to Base calldata, and how to verify a merkle proof by hand.
Sports scores and settlement results with proof
Normalized scoreboards and final results for 24 leagues, each final available with a notarized snapshot of the source: settlement-grade sports data for prediction market agents.
Change watchers with proof attached
Pay once and jurat watches a URL, JSON field, regex or sports fixture on your cadence, webhooking your agent on change with a signed source attestation attached.
Scheduled wakeups: cron for ephemeral agents
jurat holds your payload and calls your webhook at time T, once or on a recurring schedule. Persistence for AI agents that cannot stay alive between tasks.
Pre-flight: check an x402 endpoint before you pay it
Eighteen conformance checks on any x402 endpoint without settling anything: live 402 challenge, decoded payment terms, and whether the price it advertises matches the price it charges.
Signed conformance reports for x402 services
Sweep every paid endpoint an x402 service declares, grade how it advertises and gates them, and get back an ed25519-signed report the operator can publish and anyone can verify offline.
x402 payments: how buying from jurat works
Pay per call in USDC on Base via the x402 protocol: the 402 challenge flow, exact prices, and the fairness guarantee that buyers never pay for failed requests.
