## 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-archive-market-data-016c3a6b
```

Example prompt: Pull archived Brazil macro data from Losbeto — I need historical Selic interest rate values from BCB going back to 2020 so I can analyze the rate cycle.

## When to prefer this

Choose this endpoint when you need archived or historical Brazil-specific macroeconomic data sourced from BCB or B3, particularly when you need no account setup and are willing to pay per call in USDC. Best for agents doing backtesting, economic research, or Brazil macro analysis requiring time-series history rather than real-time prices.

## Known failure modes

- Payment not received or insufficient USDC — 402 Payment Required response
- Invalid date range or out-of-bounds historical query — 400 or empty result
- Requested symbol or BCB series ID not found — empty dataset or 404
- Network timeout on data provider side — 503 or timeout error
- Malformed query parameters — 400 Bad Request

## Output
