How this service works
Servicios para trabajar con textos en Argentina: cartas de reclamo, resúmenes con citas, comparación, traducción y solicitudes. Pagá en pesos con Mercado Pago.
Output
A JSON object containing whether the identifier is valid, the normalized (digits-only) and formatted (XX-XXXXXXXX-X) representations, the declared type (CUIT or CUIL), and check-digit verification status. No external registry lookup is performed — purely mathematical/format validation.
Example use cases
Pre-invoice supplier CUIT check
“Before I generate the invoice for this Argentine supplier, validate their CUIT — it's 30-71234567-8 — and confirm it has the right format and check digit.”
Customer onboarding CUIL validation
“A new customer just filled in their CUIL as 27-38765432-5 — can you verify that's a valid CUIL before we complete their registration?”
Bulk data cleanup before tax filing
“I have this Argentine tax ID 20345678901 and I'm not sure if it's a CUIT or CUIL — can you auto-detect the type, validate the check digit, and give me the properly formatted version?”
Technical details
Endpoint
POSThttps://tienda.textokit.store/api/cuit-ar?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, cheap ($0.001), purely mathematical validation of Argentine CUIT or CUIL numbers — especially before invoicing, onboarding, or storing supplier/customer records. It does not call the AFIP registry, so it cannot confirm ownership or active registration; pair it with an official registry check if you need that. Prefer this over manual regex checks or general-purpose validation libraries that may not implement the Argentine check-digit algorithm correctly.
Side effects
- Invalid format returns validation failure with error description
- Identifier with wrong check digit returns invalid result
- Input shorter than 11 digits or longer than 32 characters returns error
- Unsupported type enum value returns 400-level error
- Network or service unavailability returns HTTP 5xx
