## 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 miniframe-tools-brazilian-interest-rates-usd-brl-bcb-sgs-f6496476 -d '<json body>'
```

Example prompt: What are the current Brazilian benchmark rates right now — Selic, CDI, and the official USD/BRL PTAX sell rate? I need today's figures from the Central Bank.

## When to prefer this

Choose this endpoint when you need authoritative, up-to-date Brazilian financial benchmark rates (Selic, CDI, or PTAX USD/BRL) in a single call without managing BCB API credentials or rate-series codes yourself. Ideal for loan pricing, contract indexation, currency conversion, or any financial calculation anchored to official Brazilian Central Bank figures.

## Known failure modes

- BCB SGS API unavailable or rate-limited — endpoint may return an error or stale data
- Network timeout if BCB upstream is slow
- Unexpected schema changes from BCB SGS could break parsing
- Rate data may lag by one business day around holidays or weekends

## How this service works

Use for anything needing an up-to-date Brazilian benchmark rate: pricing a loan, indexing a contract, converting USD/BRL. No body required. Returns Selic (Copom policy rate), CDI (interbank rate) and USD/BRL (PTAX sell rate), each with its reference date, straight from the BCB's own SGS API.

## Output

Returns a JSON object with three top-level keys: 'selic' (rate_pct and effective_date), 'cdi' (rate_pct and date), and 'usd_brl' (rate and date), plus a 'source' field confirming the data came from bcb-sgs. All rates are current as of their respective reference dates.
