## 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 br-intelligence-brazilian-identifier-validation-232d6d15
```

Example prompt: Can you validate this Brazilian CNPJ number — 11.222.333/0001-81 — and tell me if it's legitimate?

## When to prefer this

Choose this endpoint when you need to validate Brazilian-specific identifiers — CPF (individual taxpayer), CNPJ (company registration), EAN13 (product barcode), NFe (fiscal notes), or Brazilian phone numbers — especially in KYC, vendor onboarding, e-commerce checkout, or compliance workflows targeting Brazil. At $0.005 USDC per call via x402 on Base, it is cost-effective for high-volume per-transaction validation without a subscription.

## Known failure modes

- Invalid or malformed identifier value returns valid: false
- Unsupported identifier type results in schema validation error
- Payment failure via x402 (insufficient USDC balance on Base) prevents the call from completing
- Missing required 'type' or 'value' query parameters returns an error
- Network timeout from the Cloudflare Worker
