Fixer - Important Announcement

We are happy to announce the complete relaunch of fixer.io into a more stable, more secure, and much more advanced currency & exchange rate conversion API platform. While the core structure of our API remains unchanged, all users of the legacy Fixer API will be required to sign up for a free API access key and perform a few simple changes to their integration. To learn more about the changes that are required, please jump to the „Required Changes“ section below.

Required Changes to Legacy Integrations (api.fixer.io)

As of March 6th 2018, the legacy Fixer API (api.fixer.io) is deprecated and a completely re-engineered API is now accessible at https://data.fixer.io/api/ The core structure of the old API has remained unchanged, and you will only need to perform a few simple changes to your integration.

1. Get a Free Fixer Access Token

Go to fixer.io and create an account. After signup, you will receive an access token immediately. If you plan on using less than 1000 requests per month, your account will be completely free. If you need more or want to use some of our new features, you’ll need to choose one of the paid options.

2. Replace API URL and add Access Key

The new API comes with a new endpoint and now requires an access key in the GET URL. Please change your API URL from api.fixer.io to https://data.fixer.io/api and attach your newly generated access key to the URL as a GET parameter named „access_key“.

Example

If your old API Call was https://api.fixer.io/latest then your new integration should point to: https://data.fixer.io/api/latest?access_key=YOUR_ACCESS_KEY

New Features

Although the core structure of the fixer API remains unchanged, we added a whole lot of improvements, 100+ more currencies, and many more features to the new Fixer API. You can read more about all new features on the new fixer.io website. Here’s a list of the most important ones:

  • Fixer is still free!
    Although we now offer a set of premium plans for more advanced users, the basic API features (e.g. getting the latest and historical exchange rates) remain completely free of charge. Minor limitations include our new 1000 requests/month limit and EUR being the only available base currency for customers using a free account. If you need more than 1000 requests per month or want to use all 170 available base currencies, you’ll need to choose one of the paid plans starting at only $10 per month.

  • Over 100 Additional Currencies
    The new Fixer API now supports over 100 additional currencies, bumping the total available currencies for conversion to 170.

  • More Reliable Data Sources & Updates every minute
    The old Fixer API was limited to currency data from the European Central Bank, which updates only once every day. The new API comes with 16+ connected data sources and data updates every hour, 10-minutes, or even every minute - depending on which subscription plan you choose.

  • More Endpoints
    The new fixer API has over 3 new endpoints, including a Direct Conversion endpoint, Time-Series conversion endpoint, and allows you to see the fluctuation of a specfic currency using our new Fluctuation endpoint. To learn more about all the new features, please head over to the API documentation at fixer.io/documentation

Next Steps

- Discontinuation of the old API

The old, deprecated Fixer API will be discontinued on June 1st, 2018. Please make sure to adjust your existing implementation to point to the new API endpoint (see above) as soon as possible in order to prevent service disruption on the planned shutdown date. In case you have any questions, please feel free to contact us using the email address below.

- Need help? Please get in touch

It’s very important for us to ensure a smooth transition to the new API Endpoint for all of our users. If you are a developer who has published a third-party plugin with Fixer, we recommend you to get in touch and share this announcement with your user base. If you need any help or have questions about the transition, please reach out at [email protected]

Travis

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

A public instance of the API lives at https://api.fixer.io. Alternatively, you can run privately with the provided Docker image.

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 are quoted against the Euro by default. Quote against a different currency by setting the base parameter in your request.

GET /latest?base=USD

Request specific exchange rates by setting the symbols parameter.

GET /latest?symbols=USD,GBP

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://api.fixer.io/latest')
  .then((resp) => resp.json())
  .then((data) => fx.rates = data.rates)
  .then(demo)

Installation

I have included a sample Docker Compose configuration in the repo.

To build locally, type

docker-compose up -d

Now you can access the API at

http://localhost:8080

In production, create a .env file in the project root and run with

docker-compose -f docker-compose.yml -f docker-compose.prod.yml up -d
