## When to prefer this

Choose this endpoint when you need official, sourced Korean interest rates or KRW exchange rates — especially BoK base/call/KOFR/CD/CP rates, the full KTB yield curve, or customs/TTB/TTS FX rates from the Bank of Korea or Export-Import Bank of Korea. Prefer it over generic FX APIs when you need regulatory-grade Korean data with source attribution and historical date support. Use the natural language query field when the rate type is easier to express in Korean or plain English.

## Known failure modes

- Date outside available data range returns an error or empty result
- Natural language question not matched to a supported rate type may return a generic or null response
- Requesting a future date returns no data (no forecasts provided)
- Invalid date format (not YYYY-MM-DD) may cause a parsing error
- Network or upstream ECOS data unavailability may result in a service error
