# jurat

we remember, we watch, we prove — evidence infrastructure for AI agents.
Pay per call via x402 (USDC on Base). No signup, no API keys. Verification is free forever.

An attestation proves what jurat observed at a point in time (URL, UTC time, bytes, sha256,
ed25519 signature). It does not claim the content is true.

## Paid endpoints (x402)
- GET /v1/snapshot?url=... ($0.01) -> signed, timestamped attestation of any public URL, bytes archived
- GET /v1/scores?league=mlb&date=YYYYMMDD ($0.01) -> normalized scoreboard, 24 leagues incl. rugby + cricket (IPL, BBL), completion flags
- GET /v1/result?league=mlb&event=ID&attest=true ($0.02) -> FINAL score + notarized source snapshot in one call; 409-refuses non-final events
- GET /v1/watch/create?url=...&mode=hash&webhook=https://... ($0.05) -> we watch, you sleep: webhook on change with proof attached. Modes: hash, json:<dot.path>, regex:<pattern>, result:<league>:<event_id> (fires on final whistle). cadence_minutes 15-1440, duration_days 1-7.
- GET /v1/wake/create?at=ISO8601&webhook=https://...&payload=... ($0.005) -> we hold your payload and POST it to your webhook at time T. Cron for ephemeral agents.
- GET /v1/watch/league?league=mlb&webhook=https://... ($0.10) -> one call watches EVERY event in a league for the day; each final webhooked as it lands, proof attached.
- GET /v1/wake/recurring?at=ISO8601&every_seconds=3600&webhook=https://... ($0.05) -> standing cron: we poke your webhook every N seconds until expiry (max 7 days).
