## 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-brazilian-cep-address-validator-ddf29395
```

Example prompt: Before we dispatch this order, can you validate the Brazilian postal code 01310-100 and confirm the full street address it maps to?

## When to prefer this

Use this endpoint when you need to validate or resolve a Brazilian CEP (postal code) in real time before fulfilling an e-commerce order, confirming a billing address, or auto-filling address forms. Prefer this over generic geocoding APIs when the specific Brazilian postal system format and cadastral data are required, and when operating within a payment-enabled agent workflow using the x402 protocol.

## Known failure modes

- CEP not found or does not exist — returns empty or error response
- CEP provided with formatting (dashes/spaces) instead of 8 bare digits — may cause validation failure
- Network or upstream data source unavailability — returns 5xx error
- Invalid non-numeric characters in CEP input — schema validation error

## How this service works

APIs brasileiras pagas por chamada via x402 (USDC, Base mainnet): dado público agregado, pronto pra um agente de IA consumir numa chamada só.

## Output

Returns the full address associated with the given 8-digit Brazilian CEP, including street name, neighborhood (bairro), city (município), state (UF), and confirmation that the code is valid. If invalid or not found, returns an error or empty result.
