Fixer is a hosted JSON API providing current and historical foreign exchange rates and currency conversion for 170 world currencies, including Bitcoin, gold, and silver. The legacy open-source-era endpoint (api.fixer.io) was deprecated in 2018 in favor of a re-engineered API at data.fixer.io that requires a free or paid access key.

Use cases

  • get latest exchange rates for 170 currencies
  • convert an amount from one currency to another
  • fetch historical end-of-day forex rates
  • add currency conversion to an e-commerce checkout
  • display multi-currency prices in an app
  • track Bitcoin, gold, and silver rates

When to choose

  • you need reliable, frequently updated exchange rate data without hosting your own data pipeline
  • you want a simple JSON API that can be integrated in minutes
  • your volume fits the free tier (under 1,000 requests/month, EUR base) or a paid plan

When to avoid

  • you need more than 1,000 free requests per month or non-EUR base currencies without paying
  • you require a fully self-hosted or open-source solution with no API key or quota
  • you depend on the deprecated legacy api.fixer.io endpoint, which no longer works
