Features
Everything you need to price the world
One request returns every currency. Paid plans add your own base, saved collections and a key for each app.
Fresh rates
Refreshed every 30 minutes. If our main data provider is down, a backup provider takes over automatically.
Any base currency
Rates are quoted against USD by default. Add ?base= to price everything against any supported currency.

Collections
Save the currencies you need with their own base currency and markup, then fetch them in one request.

Usage you can see
