Technical details
Endpoint
GEThttps://finance-api.kdlcfa.workers.dev/forex-rateWhen to prefer
Use this endpoint when you need a quick, low-cost delayed spot rate for a single specific forex pair from the supported set (EURUSD, GBPUSD, USDJPY, USDCNY, AUDUSD, USDCAD, USDCHF, USDVND). If you need multiple pairs in one call, prefer the multi-pair snapshot sibling endpoint to reduce total cost and latency. Best suited for lightweight lookup use cases — not for real-time trading systems requiring live tick data.
Side effects
- Missing 'pair' query parameter — API returns an error requiring the param
- Invalid or unsupported currency pair provided — only 8 pairs are supported (EURUSD, GBPUSD, USDJPY, USDCNY, AUDUSD, USDCAD, USDCHF, USDVND)
- Yahoo Finance upstream outage or rate-limiting — endpoint may return an error or stale data
- Payment not provided or rejected — x402 payment required before data is returned
- Network timeout from the Cloudflare Worker
