Tools
| Tool | Description | Behaviour |
|---|---|---|
| proof_fetch_evidence | Paid: fetch a public URL and return its cited, paragraph-addressable text with integrity hashes and a receipt. Uses one prepaid credit, and only when extraction succeeds. Needs a ProofFetch key sent as the MCP request header Authorization: Bearer <key> (buy one at the ProofFetch home page). Run proof_fetch_preflight first. Example: {"url":"https://example.com/"}. | Changes data |
| proof_fetch_offer | Read the offer ($0.01 a page with a 500-page card pack, or $0.50 per call through Stripe MPP) and request schema without buying. Paid cited text uses POST /v1/evidence with Stripe MPP and a caller-generated idempotency key, only with buyer payment authority. Example arguments: {}. | Read-only |
| proof_fetch_preflight | Start here: check a public URL before buying cited extraction. 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}. | Read-only |
