Output
Returns the current USD to KRW exchange rate as a numeric value, sourced from ECB reference data (Frankfurter API) with a fallback to open.er-api.com if the primary source is unavailable. Typically includes the rate value and may include a timestamp or source indicator.
Example use cases

Endpoint
GEThttps://k-data-x402-production.theblack1022.workers.dev/api/fx/usdkrw?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need the USD/KRW currency pair rate sourced from ECB reference data (a reputable, stable source). Ideal for applications targeting the South Korean market, Korea-focused financial tools, or when ECB reference rates are preferred over commercial spot rates. The dual-source fallback improves reliability over single-provider alternatives.

- Payment of $0.005 USDC not completed — 402 Payment Required response
- Rate data may be slightly delayed relative to live spot market prices
- Network timeout from upstream ECB/Frankfurter data source
