## Tools (as reported by the server, not verified)

- `freshproof\_info`: Describe FreshProof, its observation semantics, current MCP price and payment network. This tool is free.
- `verify\_proof`: Verify an existing FreshProof Proof Receipt without making a new network request. This free tool checks deterministic receipt integrity and optionally evaluates trust policy rules. Use it when you already have a proof\_id from observe\_url or verify\_url and want to re-check evidence without paying for
- `observe\_url`: Buy a timestamped FreshProof observation of a public HTTP/HTTPS URL. Returns final URL, observation timestamp, age, HTTP status, SHA-256 body hash, body size, ETag, Last-Modified, fetch duration, and whether the observation came from shared cache or a fresh public-network request. Set max\_age=0 when
- `verify\_url`: Verify what is observable at a public URL before an agent trusts, pays, or acts. This paid tool combines observe\_url and verify\_proof in one call: it buys an observation, creates or returns a Proof Receipt, and evaluates the supplied trust policy. Set max\_age=0 when current public-network evidence i
