## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability latam-datos-api-argentina-cuit-validator-a381789c
```

Example prompt: Can you validate this Argentine CUIT number for me — 20-12345678-9 — and tell me if it's valid and whether it belongs to a person or a company?

## When to prefer this

Choose this endpoint when you need a fast, low-cost programmatic check of an Argentine CUIT number's validity and entity classification — ideal for onboarding flows, invoice generation, KYC pipelines, or any workflow where confirming an Argentine fiscal ID is required before proceeding. It is purpose-built for Argentina and handles the CUIT checksum algorithm natively, unlike generic format validators.

## Known failure modes

- Invalid or malformed CUIT format returns valido: false
- Missing 'valor' query parameter results in a 400/422 error
- Non-Argentine tax IDs (e.g. CPF, RUT) are not supported and will return invalid
- Service unavailability on Render free tier may cause cold-start latency or 503 errors
- Payment failure via x402 prevents the request from being processed
