## 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 agentum-lat-cnpj-verification-a310057b
```

Example prompt: Can you check if the Brazilian company with CNPJ 11222333000181 is active and registered correctly — I need to confirm their Simples Nacional status and registered address before we close this deal.

## When to prefer this

Use this endpoint when you need real-time, authoritative verification of a Brazilian company's tax registration status directly from the Receita Federal. It is the right choice for due diligence before financial transactions, supplier onboarding, or any workflow requiring confirmation that a Brazilian CNPJ is valid, active, and correctly registered.

## Known failure modes

- Invalid or malformed CNPJ (non-14-digit input) returns a validation error
- CNPJ not found in the Receita Federal database returns a not-found response
- Receita Federal API downtime or rate limiting may cause lookup failures
- Formatting CNPJ with punctuation instead of digits-only may cause rejection

## Output
