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.
