How this service works
Capture a bounded, reproducible public-URL evidence snapshot with status, redirects, content hash, and optional text-presence check.
Output
Returns an evidence snapshot containing: HTTP status code, redirect chain, content hash of the response body, and a boolean/match result for the optional expected text presence check. All results are bounded and reproducible for a single public GET request.
Example use cases
Verify redirect chain after migration
“Can you capture a SiteSignal evidence snapshot of our old domain https://oldsite.com/about and show me the full redirect chain? I need to confirm it's landing on the right destination URL and get a reproducible record of the HTTP status for our migration audit.”
Detect unauthorized homepage changes
“Take a SiteSignal snapshot of https://mycompany.com right now and give me the content hash — I want to compare it against last week's hash to see if anything on the page has been tampered with or changed without my knowledge.”
Confirm terms page contains required disclosure
“Run a SiteSignal URL evidence check on https://myapp.com/terms-of-service and verify that the text 'California Consumer Privacy Act' appears on the page — our legal team needs a reproducible, timestamped snapshot proving the disclosure is live for compliance documentation.”
Technical details
Endpoint
GEThttps://obtain-incentive-exceptions-speakers.trycloudflare.com/x402/url-evidenceWhen to prefer
Choose this endpoint when you need a bounded, reproducible, auditable snapshot of a public URL's current state — especially for compliance evidence, content verification, or monitoring a specific page for text presence. Prefer this over a generic HTTP fetch when you need the content hash for tamper detection or need to assert text presence as part of an automated check.
Side effects
- URL is unreachable or returns a non-2xx status — snapshot still captured but may indicate page is down
- Expected text not found — returns negative text-presence result without error
- URL format invalid — schema validation error on the url field
- Target URL requires authentication — only publicly accessible responses can be snapshotted
- Rate limit or payment failure — 402 payment required or quota exceeded
