README

Integrate the powerful Exchange Rates API from Abstract in your PHP project in a few lines of code.

The Exchange Rate API is an REST API that allows you to:

• look up the latest exchange rates for 80+ currencies via the live endpoint
• get historical exchange rates using the historical endpoint
• convert an arbitrary amount from one currency to another using the convert endpoint

It's very simple to use: you only need to submit your API key and a currency symbol (such as "USD"), and the API will respond with current exchange rate, historical data, or convertion rates.
