## 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 verifik-ai-brazil-cpf-identity-validation-0dafbe2b -d '<json body>'
```

Example prompt: Can you verify the Brazilian CPF identity document for document type 'CPF', document number '123.456.789-09', and date of birth '1985-03-22'?

## When to prefer this

Use this endpoint when you need to validate a specific Brazilian national ID (CPF) document for KYC/AML compliance purposes, particularly for LATAM-facing workflows. Prefer this over generic identity APIs when you need deep Brazilian registry coverage and pay-per-call pricing without a subscription.

## Known failure modes

- Invalid or non-existent document number returns a validation error or empty data payload
- Incorrect date of birth causes a mismatch or rejection response
- Unsupported document type returns a parameter error
- Payment of 0.3 USDC not processed results in HTTP 402 and no data returned
- Brazilian registry service temporarily unavailable causes a timeout or upstream error
