Longhorn by BullPay allows developers to add blockchain support to their applications. The API delivers enterprise class features including real-time and historical transactions, summaries, and auditing data. Longhorn is a REST interface with JSON responses and API Keys are used for authentication. The API uses a patent-pending memory-mapped database technology which provides 5 blockchains (Bitcoin, Litecoin, Ethereum, Dash, and Dogecoin). Litecoin TestNet is also supported. The API currently offers 12 endpoints for sending transactions, retrieving summaries, and more. A free package is available that allows for 5,000 calls a day.
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.
