Getting Started with coinlayer API

API Access Key

Your API access key is the only token for accessing the coinlayer API. By signing in to the dashboard, you must search your API access key.

Upon completion of your registration, a forever free API key will be issued. This is more than enough for training and should be sufficient enough for essential use.

Further, you get a window to validate the API after logging in. The database query will be running, and the data can be expanded through the endpoints for all available JSON cryptocurrencies. For convenience, the required query parameters are highlighted with orange and optional parameters with blue.

To authenticate the API, append the access_key parameter to the API’s base URL and set it to your API access key value.

Base URL:

Append your API Access Key:
? access_key = YOUR_ACCESS_KEY

The main configuration is the base URL (, the endpoint (live, list, convert, etc.), and the API’s permission key. The response returns the question performance status, links to terms and privacy sites, unique endpoint features, destination currencies, and specific endpoint datasets. The coinlayer supports JSON callbacks so that the GET callback optional parameter will wrap the result within a function.

API Response

As you can see above, we have used the Live endpoint while appending the API access key. So, the basic API response for all available cryptocurrencies is shown below in JSON format with the exchange rate data:
