# Frankfurter
|

|
Frankfurter is a free and open source API for current and historical foreign exchange rates. It tracks data published by the European Central Bank. Rates update around 4PM CET every working day.
|
|
|
|
Use our public instance or self host with Heroku or Docker.
|
|
|
|
## Examples
|
|
|
|
Get the current foreign exchange rates.
|
|
|
|
```http
|
|
GET /latest HTTP/1.1
|
|
```
|
|
|
|
Get historical rates for any day since 1999.
|
|
|
|
```http
|
|
GET /2000-01-03 HTTP/1.1
|
|
```
|
|
|
|
Get historical rates for a time period.
|
|
|
|
```http
|
|
GET /2010-01-01..2010-01-31 HTTP/1.1
|
|
```
|
|
|
|
Get historical rates for a time period up to the present.
|
|
|
|
```http
|
|
GET /2010-01-01.. HTTP/1.1
|
|
```
|
|
|
|
Get a list of available currency symbols, along with their full names.
|
|
|
|
```http
|
|
GET /currencies HTTP/1.1
|
|
```
|
|
|
|
Rates quote against the Euro by default. Quote against a different currency.
|
|
|
|
```http
|
|
GET /latest?from=USD HTTP/1.1
|
|
```
|
|
|
|
Request specific exchange rates.
|
|
|
|
```http
|
|
GET /latest?to=USD,GBP HTTP/1.1
|
|
```
|
|
|
|
Convert a specific amount.
|
|
|
|
```http
|
|
GET /latest?amount=1000&from=GBP&to=USD HTTP/1.1
|
|
```
|
|
|
|
With a full list of currencies, time series grow large in size. For better performance, use the to parameter to reduce the response weight.
|
|
|
|
```http
|
|
GET /2016-01-01..2016-12-31?from=GBP&to=USD HTTP/1.1
|
|
```
|
|
|
|
Here we return the current GBP/USD currency pair with JavaScript.
|
|
|
|
```js
|
|
// Fetch and display GBP/USD
|
|
fetch('/latest?from=GBP&to=USD')
|
|
.then(resp => resp.json())
|
|
.then((data) => { alert(`GBPUSD = ${data.rates.USD}`); });
|
|
```
|
|
|
|
Cache data whenever possible.
