Fiscal

RFC Status and LCO Validation

Credits: 1 per call.

Validates the structure and current status of a Mexican RFC (Registro Federal de Contribuyentes) against the SAT registry. Returns the taxpayer type (individual or legal entity), registration status, and the official SAT message.

Use this endpoint to confirm that the RFC your customer provided is real, well-formed, and currently active with SAT before extending credit, issuing invoices, or signing contracts.

Risk Level Matrix (riskLevel):

NONE (envelope type: SUCCESS): RFC exists in the SAT padrón and is authorized to issue / receive invoices (isBillable: true). Safe for automated approval.
LOW (envelope type: RFC_NOT_INVOICEABLE): RFC exists in the SAT padrón but is restricted for invoicing — typically a legal entity that has not completed its fiscal-status onboarding or has been suspended. The taxpayer is real, just not currently invoiceable.
CRITICAL (envelope type: RFC_NOT_FOUND): RFC is not registered in the SAT padrón. Either it was never issued, or the value provided is a typo or fabricated. Do not extend credit, issue invoices, or accept as a counterparty without further verification.

MEDIUM and HIGH are not produced by this endpoint — the SAT padrón only distinguishes the three outcomes above.

CSF Data Extraction & Validation (Multi-input)**Credits:** 1 per call. Extracts structured data from a Constancia de Situación Fiscal (CSF) — the official PDF document issued by SAT that proves a taxpayer's fiscal situation. You can submit the CSF as a base64-encoded file (PDF/PNG/JPG) and get back the full content as JSON, or alternatively pass RFC + CIF (the tax-certificate code) to retrieve the same data directly from SAT's public QR validator. Returns the legal name, address, fiscal regime, economic activities, registration date, and tax obligations. Use this endpoint to automate vendor onboarding and to keep your records of partners' fiscal data continuously up to date.
