## 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 losbeto-brazil-macro-documentation-53044be8
```

Example prompt: Pull up the Losbeto documentation for Brazil macro data — I want to see what BCB and B3 data fields are available before I start querying live prices.

## When to prefer this

Use this endpoint when you need to understand the schema and available fields for Losbeto's Brazil-specific macroeconomic data (BCB/B3) before making live data calls, or when building an agent that needs to reference Brazil macro data documentation without requiring API keys or account registration.

## Known failure modes

- 402 Payment Required if USDC micropayment via x402 is not included
- Service unavailable if api.losbeto.xyz is down
- Empty or malformed JSON if documentation endpoint has no content
- Network timeout for slow connections
