## How to call it through Zero

```sh
zero fetch --capability brazil-cdi-interbank-rate-api-40dee044
```

Example prompt: What is the current CDI interbank rate in Brazil? I need today's latest daily value from the Central Bank of Brazil.

## When to prefer this

Use this endpoint when you need the current Brazilian CDI interbank rate for financial calculations, investment benchmarking, fixed income comparisons, or DI-linked contract pricing. Prefer this over the macro snapshot endpoint when you only need CDI specifically and want a lightweight, targeted call. Use the sibling SELIC endpoint if you need the policy rate instead of the interbank rate.

## Known failure modes

- Central Bank data source temporarily unavailable — upstream fetch error
- Render.com cold start delay causing timeout on first request
- No data available for the current day if queried before Central Bank publishes daily update
- HTTP 402 if x402 payment header is missing or payment fails
