## How to call it through Zero

```sh
zero fetch --capability cbr-official-exchange-rates-api-2cc8ae9e
```

Example prompt: What are today's official Central Bank of Russia exchange rates for USD, EUR, and CNY in rubles?

## When to prefer this

Use this endpoint when you need the official, authoritative ruble exchange rates published by the Central Bank of Russia — distinct from market/trading rates. Ideal for compliance, invoicing, accounting, or any Russian regulatory context where CBR rates are legally required. Prefer over MOEX ISS quotes when you need the official fixing rather than live market prices.

## Known failure modes

- Invalid or unsupported ISO currency code returns empty or missing rate entry
- Weekend/holiday dates may return the most recent available rate rather than a same-day rate
- Network timeout if CBR upstream is slow or unavailable
- Empty currencies array defaults to USD/EUR/CNY only
