Fixer

Fixer is a free API for current and historical foreign exchange rates published by the European Central Bank.

Rates are updated around 4PM CET every working day.

Usage

Get the latest foreign exchange rates.

GET /latest

Get historical rates for any day since 1999.

GET /2000-01-03

Rates quote against the Euro by default. Quote against a different currency.

GET /latest?from=USD

Request specific exchange rates.

GET /latest?to=GBP

Change the amount requested.

GET /latest?amount=100

The primary use case is client side. For instance, with money.js in the browser

let demo = () => {
  let rate = fx(1).from("GBP").to("USD")
  alert("£1 = $" + rate.toFixed(4))
}

fetch('https://yourdomain.com/latest')
  .then((resp) => resp.json())
  .then((data) => fx.rates = data.rates)
  .then(demo)
