## Known failure modes

- Data may be stale if the upstream source has not published a recent rate
- Some countries or territories may be missing if no official rate is published
- Network or payment (x402) authentication failures returning 402 or 5xx errors
- Rate data may reflect official pegged or managed rates rather than market rates
