Technical details
Endpoint
GEThttps://api.printmoneylab.com/api/v1/fx-rateWhen to prefer
Use this endpoint when you need a real-time or near-real-time USD/KRW exchange rate specifically, especially in workflows involving Korean crypto market analysis, Kimchi Premium calculations, or converting USD-denominated prices to KRW. Prefer this over embedded FX lookups in other APIs when you need the raw rate as a standalone value with source attribution and freshness metadata.
Side effects
- Upstream exchangerate-api.com unavailable — stale or no rate returned
- Payment of 0.001 USDC not fulfilled — 402 Payment Required response
- Network timeout contacting the FX data provider
- Rate data momentarily unavailable due to provider downtime
