proof

proof_fetch_evidence

Fetch a public URL and return its cited, paragraph-addressable text with integrity hashes and a receipt. Uses one credit from a ProofFetch key, and only when extraction succeeds. Needs the key sent as the MCP request header Authorization: Bearer <key>: a free key holds 1,000 extractions (no card, POST /v1/keys/free or the ProofFetch home page); a paid key holds 500 for $5.00 (sold on the ProofFetch home page). Example: {"url":"https://example.com/"}.

proof_fetch_offer

Returns the offer and request schema without buying. Full cited text: 1,000 free extractions with a free key (no card), then $0.01 a page either way: a 500-page card pack for $5, or $0.50 per Stripe MPP call, which returns the page plus an API key holding 49 more. Cited text uses POST /v1/evidence with a caller-generated idempotency key. Example arguments: {}.

proof_fetch_preflight

Free: checks a public URL and returns fetchability, provenance, hashes, deterministic injection indicators and a free preview of the first 1,000 or so characters of text (short pages come back whole); not a safety guarantee. No payment or purchase. Example: {"url":"https://example.com/","maxChars":30000}.
