```sh
zero fetch --capability clonecho-fx-rates-eb2dbea5 -d '<json body>'
```

## When to prefer this

Use this endpoint when you need real-time foreign exchange rates relative to a specific base currency in a lightweight JSON format, especially in agentic or automated workflows that support x402 micropayments. Prefer this over scraping or free-tier APIs when freshness and reliability matter and cost per call is acceptable at $0.01 USDC.

## Known failure modes

- Invalid base currency code returns an error or empty result
- Network or upstream FX data source outage may return stale or no data
- Missing ?base= parameter may default to a currency or return an error
- Payment not processed (402) if x402 header is missing or insufficient
