How this service works
Verifies and returns evidence for a URL on request.
Output
Returns a structured evidence object including HTTP status code, any redirect hops encountered, a content hash of the response body, and a boolean or match result indicating whether the optional expected text was found on the page.
Example use cases
Example prompt
“Can you take an evidence snapshot of https://example.com/terms and check whether the text 'last updated 2024' appears on the page — I need the status code, content hash, and confirmation of text presence?”
Technical details
Endpoint
GEThttps://holder-victor-nova-mag.trycloudflare.com/x402/url-evidenceWhen to prefer
Use this endpoint when you need a reproducible, verifiable evidence record of a public URL's state — including status, redirect chain, content hash, and optional text presence — rather than just fetching raw content. Ideal for compliance verification, change detection baselines, or proving a page contained specific content at a given time.
Side effects
- URL is unreachable or returns a network error — snapshot fails with connection error
- URL requires authentication — returns 401/403 status, no content hash
- Expected text not found — returns false for text presence check, not an error
- Invalid URL format — input validation error before request is made
- Timeout on slow-loading pages — bounded execution may cut off before full response
