Convert amounts between ECB-supported currencies using the European Central Bank's official daily euro reference rates. Returns the two source observations, publication date, explicit cross-rate math, converted amount, attribution, freshness, and a non-market-quote disclaimer. The underlying ECB data is free; this fee covers validation and machine-ready delivery.
