## When to prefer this

Use this endpoint when you need real-time or live foreign exchange rates for one or many currency pairs simultaneously, especially when integrating with a pay-per-call x402 workflow on Base. Prefer this over cached or daily-updated FX sources when currency freshness matters for pricing, conversion, or portfolio decisions.

## Known failure modes

- Invalid currency code returns error or empty rate
- Unsupported source currency may return error
- Network timeout from upstream exchangerate.host service
- Malformed currencies parameter (e.g. incorrect comma-separation) returns error
- Rate limiting or payment failure results in HTTP 402

## How this service works

## Output
