PAID, not part of the free quota and not a free tool: does not fetch or return the dossier. Validates a persona moral RFC locally, then returns the x402 payment pointer so an x402 client can pay and GET it. Price: $0.03 USDC on Base (eip155:8453) per successful HTTP 200; no account or API key; 4xx is not charged. GET https://mx.redtapeapi.com/v1/mx/supplier/dossier?rfc= — Supplier dossier for a persona moral. It aggregates SAT Art. 69 lists, CSD sin efectos, full 69-B history, 69-B Bis and the Padrón de Importadores, with an explainable risk score. This tool does not fetch or include that data. Personas morales only (12-character RFC). A 13-character persona física RFC is rejected here and by the route with HTTP 400. Manifests: https://mx.redtapeapi.com/openapi.json and https://mx.redtapeapi.com/.well-known/x402. Not an official SAT service.
