Api Endpoint

api-staging.eckari.com

European Central Bank euro foreign exchange reference rate for a pair - the official daily fix used for accounting, invoicing and reporting - latest or any date in the last 90 days. The ECB publishes EUR/XXX only, so inverse and cross rates are computed from the same fix and named in rate_derivation. One fix per TARGET working day, not a tradable market rate. Use when: Convert or report an amount at an official daily rate both sides of a contract can verify against the ECB.
