About this API

Every price endpoint on this API accepts a ?currency= parameter and converts on the fly. But sometimes you need the raw rates: that's what this endpoint is for. List every supported currency, or convert a specific amount between two currencies.

Rates refresh daily from upstream ECB data. Use the same API key as every other endpoint.

Currency API — FAQ

Which currencies are supported?

Over 100, including USD, EUR, GBP, CNY, RUB, BRL, PLN, JPY. GET /currency/api/list for the full list.

How often do rates refresh?

Daily from ECB upstream data. Cached server-side for performance.

Can I convert prices inline on other endpoints?

Yes — every price endpoint takes ?currency=EUR (or whatever). The conversion is applied server-side using the same rate table.
