Foreign-exchange rate
Current exchange rate between two fiat currencies. Sources differ: an ECB reference rate is not a tradeable rate and is published once per working day.
price-ascending: candidates are ordered by the listed price of the operation, with no managed-first preference applied. Unlike /v1/apis, this surface does not rank Apiosk-settled listings above federated ones — a comparison that reorders on commercial grounds is not a comparison. Pass sort=managed_first for the catalog's ordering.
| Provider | Operation | Price | Settlement | Notes |
|---|---|---|---|---|
| exchangerate.host | GET /live | $0.05 | via Apiosk | |
| Frankfurter | GET /latest | $0.05 | via Apiosk | ECB reference rates: published once per working day, not a tradeable rate. |
| Twelve Data | GET /exchange_rate | $0.05 | via Apiosk | Takes the pair as a single symbol (USD/JPY); the capability's separate base/quote inputs do not map onto it directly. Does not accept: base. |
| Alpha Vantage | GET /query | $0.06 | via Apiosk | Multiplexed endpoint: the function parameter selects the operation. |
Compared: listed price, settlement rail and input compatibility. Not measured yet: latency, reliability, result quality, and provider terms such as rate limits, jurisdiction and licensing.
