Why 10,000+ developers love Abstract's APIs

Easy to implement and maintain

We built Abstract because most of the API's we've used in the past simply weren't great. Our APIs are built the way we think API's should be: with excellent documentation, multiple easy to use libraries, and tutorials to get you started.

Speed and scale built into everything we do

Something like IP geolocation is probably part of a critical business processes and flow, so we built it (as all of our APIs) for use at scale and at blazing speeds. These aren't just marketing phrases, but fundamental features of our APIs.

Reliable uptime and great support

Developers trust Abstract because of our reliable uptime and excellent technical support that will help get you live quickly, keep you running smoothly, and resolve any issues you have fast regardless of where you are or what you're building.

Frequently Asked Questions
about Exchange Rate and Currency Conversion API

How accurate is the currency data?

We source our data from multiple trusted providers to ensure the exchange rates and currency conversion data we provide to you is as close to market as possible. To do this, we collect exchange rate data from multiple central banks (such as the European Central Bank and the Bank of Japan) and process them to provide the latest rates.

How often is your exchange rate data updated?

Our core data is updated every 60 seconds for most currencies and currency pairs. However, you will have different levels of accuracy based on your plan. For example, the data accessible via our free plan is typically updated every 45-60 minutes, while our paid plans have access to currency data that's updated every 60 seconds.
