A Free API That Solves the Annoying Parts of Currency Data

Getting clean, accurate exchange rates into a project shouldn’t be a hassle, but it often is. A lot of APIs look great until you hit a rate limit, get blocked by a signup form, or realize that the crypto data you need is behind a paywall. Historical rates are often limited to just a few months, and even basic tax information like EU VAT rates is hard to find in one place.

This API makes things easier. It covers both forex and crypto, offers real-time and historical data, and even includes EU VAT rates for anyone building tools that need pricing or tax accuracy across borders. There’s no signup wall, no payment required, and no delay in testing it. You can just hit the endpoint and get usable data immediately.

It’s especially useful if you’re working on projects like currency converters, analytics dashboards, pricing automation, or invoicing tools that adapt by region. The historical data goes back to 1999 for fiat and to Bitcoin’s start for crypto, so you can dig into trends without needing another source.

Everything is returned in clean JSON with consistent formatting, so you don’t have to waste time cleaning or reformatting data before using it. That alone makes it easier to plug into prototypes or shipping tools without adding extra complexity.
