What it does
FX Rates gives you foreign exchange rate data for a chosen base currency. Send the base query parameter as a three-letter currency code, or omit it to use the default USD, and get a response envelope with success and code plus the rate data blocks returned by the service.
Use FX Rates when you need live or latest currency reference data for pricing, checkout display, reporting, or financial dashboards. It is a fit for applications that convert amounts across currencies, reconcile multi-currency transactions, or show users values in their local currency while keeping a single source of truth for the base currency.
The response is intentionally lightweight at the top level: success tells you whether the request completed, and code gives you the numeric status. Any additional module blocks are returned in the body as defined by the service, so you can parse the currency data your integration needs without guessing at extra fields.
If you work with invoices, subscription billing, or exchange-rate lookup flows, FX Rates keeps the contract simple: request a base currency, read the result envelope, and use the returned rate payload in your own calculations.
