Today we will learn how to use coinlayer’s public API to get historical pricing data of any date. The data is real time and dynamic you can change dates or can get data of as much as coins as you want.

Getting Historical Pricing Data

As you can see above I got this data from coinlayer.com which is an amazing API provider for Price Indexing, conversion, Historical data. There can be a lot of functions that can be achieved using public API of coinlayer. Some advanced functionalities might require authenticated API keys and paid memberships.

Response Example:

{

"success":true,

"terms":"https:\/\/coinlayer.com\/terms",

"privacy":"https:\/\/coinlayer.com\/privacy"

,"timestamp":1553990360,

"target":"USD",

"Historical":true,

"Date":"2019-03-30",

"rates":{"ETH":142.746323,"KMD":1.101378}

}

http://api.coinlayer.com/api/2019-03-30?access_key=007866dcbd35cf6d14951e425a61c422&symbols=ETH,KMD

As you can see this API endpoint will return me the JSON file for historical data according to the date I entered 30th March 2019. The date and the coins are my parameters, which is dynamic and can be changed for different results.

Response Example:

{

"success":true,

"terms":"https:\/\/coinlayer.com\/terms",

"privacy":"https:\/\/coinlayer.com\/privacy"
