How this service works
Live + reference foreign-exchange (forex) rates, base USD. LIVE near-real-time mid quotes for the 12 most-traded currencies (EUR, GBP, JPY, CHF, CAD, AUD, NZD, CNY, HKD, SGD, SEK, KRW), refreshed every minute with an honest market-open/stale flag, PLUS the official ECB daily reference table for ~30 currencies. Derive any cross-rate or pair. For agents pricing cross-border ops, treasury, invoicing and FX conversion. Keyless, pay-per-call.
Output
Returns a JSON object with live USD-based exchange rates (AUD, CAD, CHF, CNY, EUR, GBP, HKD, JPY, KRW, NZD, SEK, SGD) timestamped to the second with stale/market-open flags and source attribution (Yahoo Finance), plus ECB reference rates for a recent date. Also includes meta fields indicating degraded status and data freshness.
Example use cases
Example prompt
“What are the current USD exchange rates for major currencies like EUR, GBP, JPY, and AUD — are they live or stale, and is the market open right now?”
