Additional notes

Look up exchange rate history for a currency pair

Set queryParams.from to the source currency code and queryParams.to to the target currency code. To narrow the period, add the optional queryParams.start_date and/or queryParams.end_date string fields.

Strale describes this capability as returning daily historical rates and summary statistics: average, minimum, maximum, and percentage change. Use the response’s own currency pair, dates, and values when interpreting a result. The request has no amount field, so it does not calculate a specific conversion total or transaction fee.

The current Strale capability catalog names Frankfurter.app and ECB historical exchange rates as the data source. See the Strale capability listing, Frankfurter documentation, and the Tool input definition.
