REST API Documentation

Authentication

There are 2 ways to authenticate with the REST API:

You can send the "token" key with every request to our API but this may subject to some security problems:
Example: https://currencydatafeed.com/api/data.php?currency=EUR/USD&token=YOUR_ACCESS_TOKEN
You can send the token as a part of the request header. If token is sent via header, you don't need to send it again with every request so your API_KEY won't be exposed with the request. Header should be: 'Authorization: Bearer ACCESS_TOKEN'

Websocket Documentation (Open BETA)

Websocket Connection

Websocket provides live data for the specified currencies. Websockets are available only to ultimate plan or upper. The websocket URL is provided on your control panel's navigation if you are a subscribed user for ultimate plan or upper. Using this url, you can connect to our websocket. After the connection, you will recieve:

Welcome, you are connected to CDF websocket!. Please login in 10 seconds.

which means that you have successfuly connected to our websocket. After recieving this, you have to send login parameters in 10 seconds or you will be disconneceted:

login_YourMailAddress:YourAPIKey

After a successful login you will receive:

Login success. Please subscribe to quotes to start recieving data...

You have to subscribe to currencies you would like to get data as JSON as below:

subscribe_EUR/USD+USD/JPY+EUR/JPY+USD/SEK+EUR/USD

That’s all. You will recieve all pairs in the first push, after that, only the pairs that has an update on latest price will be pushed to you. If no pair has an update there won’t be any data delivered to you. The response will be the same as the REST API response provided to live data requests.

Details of Using REST API and Websocket

How API Requests Are Counted?

Nearly all the data feed companies count each quote request as 1 API request. For example, if you make a single request that asks for multiple currencies like EUR/USD, USD/JPY, EUR/SEK, USD/RUB and GBP/USD, this counts 5 API requests but with CurrencyDataFeed.Com, to give you more opportunities and space, we count this example request as 1 API request. We count 1 API request for each 5 quotes.

Some Examples:

You made a single request to get 5 currency pairs. This counts as 1 API request.
You made a single request to get 46 currency pairs. This counrs as 10 API requests.

For Source Currency requests , each 5 target currency counts as 1 API request.

Some Examples:

You set the source currency as NZD and set 5 target currencies. This counts as 1 API request.
You set the source currency as NZD and set 9 target currencies. This counts as 2 API request.

For historical and time range queries, every request for a single currency is counted as 1 API request. Only 1 currency pair may be requested for time range queries but you can ask for many currencies for a historical close price with a single call.

Some Examples:

You made a request to get the EUR/USD Close Value for 01/04/2017 , this counts as 1 API request.
You made a request to get the EUR/USD , USD/RUB and EUR/SEK Close Value for 01/04/2017 , this counts as 3 API requests.

For Currency Conversion queries, each request is counted as 1 API request.

For Crypto queries, every 5 requests are counted as 1 API request.

Which Values Are Provided?

The values provided vary according to subscribed plan. You can check all the plans by clicking pricing link on the navigation bar.

For historical values, we provide open,close,low and high values.
For time-range queries, we provide open,close,low and high values.
For classical currency requests, we provide last price,change number,change percent,ask,bid,daily low and daily high values.
