proof

proof_fetch_offer

Read the $0.50-per-successful-extraction offer 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: {}.

proof_fetch_preflight

Start here: check a public URL before buying cited extraction. Returns fetchability, provenance, hashes and deterministic injection indicators, not page text or a safety guarantee. No payment or purchase. Example: {"url":"https://example.com/","maxChars":30000}.
