## 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 brazil-macro-api-selic-target-rate-a1e1d45e
```

Example prompt: What is Brazil's current Selic target rate as set by the central bank?

## When to prefer this

Choose this endpoint when you need the official Brazilian central bank policy rate (Selic target) in a lightweight, single-field lookup. Prefer it over scraping BCB's website or using broader economic data aggregators when you want a programmatic, low-cost, near-real-time answer. If you also need related Brazilian macro indicators (CDI, IPCA, PTAX, Focus forecasts), the sibling 'all-in-one' endpoint on the same host may be more efficient.

## Known failure modes

- Service temporarily unavailable due to Railway hosting downtime
- Stale data if BCB source has not been recently updated after a COPOM meeting
- Rate not yet updated following a very recent COPOM rate decision
- HTTP 402 Payment Required if the x402 payment header is missing or insufficient

## How this service works
