Endpoint
GEThttps://agent402.tools/api/fx-rateWhen to prefer
Use this endpoint when you need authoritative, ECB-sourced reference exchange rates for mainstream currency pairs. Prefer this over general quote endpoints when you specifically need ECB rates with the associated date, or when performing financial calculations that require a trusted central bank reference rate rather than a market/bid-ask rate.
Side effects
- Invalid or unsupported 3-letter currency code returns an error (e.g. unknown currency)
- Missing required 'from' or 'to' query parameters results in a 400 bad request
- ECB may not have rates for exotic or non-standard currencies
- Network/upstream failure if Frankfurter API is unavailable
