Payment is standard x402: sign an EIP-3009 TransferWithAuthorization for the price and send the base64 payload in X-PAYMENT; the service verifies it through the x402 facilitator, answers, and settles it on Base in the same request, returning the transaction hash in the response and at /v1/settlement/{nonce}. A transfer you broadcast yourself is accepted in the same header. POST /v1/page-read with {\"url\":\"https://...\"} to get one public page as cleaned text plus title, headings, JSON-LD and outbound links, fetched with no JavaScript execution. POST /v1/endpoint-verify with {\"url\":\"https://...\"} to get reproducible proof that an HTTP endpoint answered: status, elapsed milliseconds, content type, byte count and the first 400 characters. Both cost 0.02 USDC. POST /v1/licence-audit with {\"url\":\"https://...manifest\",\"distribution\":\"saas\"} to get every package in a public manifest resolved against npm or PyPI, its licence cited to the registry document it came from, obligation findings scored against your distribution model, and a CycloneDX 1.5 SBOM - 0.25 USDC.
