Notarize Any Public Web Page Or API Response API
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.
