## 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-official-rates-3361dbc3
```

Example prompt: What are the current official Brazilian rates right now — Selic, CDI, and the commercial dollar exchange rate — so I can calculate the BRL return on an investment?

## When to prefer this

Choose this endpoint when you need all three core Brazilian official financial rates (Selic, CDI, and commercial dollar) in a single call, avoiding the complexity of querying Banco Central do Brasil and B3 separately. Ideal for AI agents performing BRL-denominated financial calculations, FX conversions, or monitoring Brazilian monetary policy without managing multiple data sources. Prefer this over scraping official government sites or assembling rates from multiple APIs.

## Known failure modes

- Upstream Brazilian government data source temporarily unavailable — may return 503 or stale data
- Rate data not yet updated for the current business day (e.g., early morning before market open)
- Network timeout if official source APIs are slow to respond
- Payment failure via x402 if USDC balance is insufficient
