The coinlayer REST API was built to deliver on-demand real-time or historical cryptocurrency exchange rates in JSON format. Crypto data is sourced from more than 25 worldwide exchanges, features more than 385 coins and can be accessed using any programming language, framework and device. The API is free for a limited amount of monthly API requests and can be used at premium level to gain access to features like 60-second updates, conversion and time-series endpoints, and much more.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
