## When to prefer this

Choose this endpoint when you need an authoritative, official US Treasury-sourced exchange rate rather than a commercial forex feed. Ideal for regulatory filings, government-adjacent financial reporting, or when official government FX data is specifically required. At $0.001 per call it is extremely cost-effective for spot lookups.

## Known failure modes

- Invalid or unsupported currency code returns an error or empty result
- Currency not tracked by US Treasury returns a 404 or null rate
- Rate data temporarily unavailable due to Treasury data source lag
- Malformed currency path parameter causes a 400 error
