ECB daily euro reference exchange rate

Latest daily ECB euro foreign-exchange reference rate for one target currency, via Frankfurter. EUR base; includes observation date. ECB data is free at ecb.europa.eu; Apiosk charges for retrieval. Not intraday, historical rates, Euribor or trading quotes.

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.

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.
