How this service works
Landing page para tu negocio en 24 horas: textos, diseño para celular y botón de WhatsApp. Boceto gratis: ves la primera versión antes de pagar. USD 39 de lanzamiento.
Output
Returns a JSON object with: whether the CUIT/CUIL is valid, the formatted version with dashes, the normalized version without dashes, the prefix (e.g. '20', '27', '30'), the entity type ('person' or 'company'), and the expected check digit. Validation is structural and offline — no AFIP/ARCA registry lookup is performed.
Example use cases
E-commerce checkout CUIT verification
“Before we process this Argentine customer's invoice, can you validate their CUIT 27-30456789-3 and confirm it's formatted correctly?”
Onboarding form data cleansing
“I have a list of CUIT numbers entered by users, starting with 30-71234567-4 — can you validate that one and tell me the expected check digit and entity type?”
Freelancer identity pre-screening
“A contractor sent me their CUIL as 20304567896 with no dashes — can you validate it, format it properly, and tell me what kind of entity it is?”
Technical details
Endpoint
POSThttps://landingen24h.com/api/x402/ar/cuit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, offline structural validation of Argentine CUIT or CUIL numbers — e.g. during form submission, data cleansing, or pre-processing steps where a live AFIP registry lookup is not required or available. It is ideal for high-throughput validation at $0.01 per call without depending on Argentine government APIs.
Side effects
- Invalid or malformed CUIT format returns valid: false with no further breakdown
- CUIT with wrong checksum digit returns valid: false and shows expected_check_digit
- Missing or empty cuit field may return an error or invalid response
- No live AFIP lookup — a structurally valid CUIT for a non-existent entity will still return valid: true
