## 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-background-check-c5e10549 -d '<json body>'
```

Example prompt: Run a background check on a Brazilian individual using document type CPF, document number 123.456.789-09, and date of birth 1985-06-15.

## When to prefer this

Use this endpoint when you need to perform KYC identity verification specifically for Brazilian individuals using national document numbers (CPF, RG, etc.) and pay only per validation with no subscription required. Prefer this over generic identity APIs when you need LATAM/Brazil-specific government registry coverage and want per-call USDC micropayments via x402.

## Known failure modes

- Invalid document number format returns validation error
- Document not found in Brazilian registries returns empty or not-found result
- Incorrect date of birth causes mismatch or rejection
- Unsupported documentType value returns 400 error
- Payment not processed via x402 returns 402 Payment Required
- Network or upstream registry unavailability returns 503 or timeout
