How this service works
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.
Output
A cryptographically signed (ed25519) attestation object containing the final resolved URL, UTC timestamp of capture, HTTP status code, content type, byte length, SHA-256 hash of the response body, and a reference to the archived bytes — usable as tamper-evident legal or settlement-grade evidence of what the URL returned at that moment.
Example use cases
Example prompt
“Take a notarized snapshot of https://example.com/terms-of-service right now — I need a signed, timestamped cryptographic attestation with the SHA-256 hash and archived bytes as settlement-grade evidence of exactly what that page says today.”
Technical details
Endpoint
GEThttps://jurat.dev/v1/snapshotWhen to prefer
Choose this endpoint when you need cryptographically verifiable, settlement-grade proof of what a public URL returned at a specific point in time — particularly for legal evidence, smart contract settlement, dispute resolution, compliance documentation, or any scenario where a human-readable screenshot is insufficient and tamper-evident integrity is required. Prefer this over simple web scraping or screenshot tools when the authenticity and integrity of the captured content must be provable to a third party.
Side effects
- URL is unreachable or returns a non-2xx status — attestation may still be issued but will reflect the error status
- URL redirects to a non-public or protected resource — final URL in attestation will reflect redirect destination
- Timeout fetching the target URL — request fails with an error response
- Invalid or missing 'url' query parameter — returns a validation error
- Payment not completed via x402 protocol — request is rejected before snapshot is taken
