Price

This is a completely free cryptocurrency API.

Special Capabilities

There are only three available API endpoints, but they offer a lot of power:

  1. The first endpoint allows you to get a list of cryptocurrencies sorted by market cap, from highest to lowest. You’re able to configure the starting point as well as the number of results returned.
  2. The second endpoint allows you to get the information on a single crypto token.
  3. The final endpoint allows you to get global cryptocurrency data.
