# jurat.dev Notarized URL Snapshot

> jurat.dev Notarized URL Snapshot is a paid API for AI agents from jurat.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-16).

Returns a signed, timestamped (ed25519) cryptographic attestation of exactly what a public URL returned, including final URL, UTC time, HTTP status, content type, byte length, and SHA-256 hash, with the bytes archived.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability jurat-dev-notarized-url-snapshot-9db371b8
```

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.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
