The Syscoin API is a full REST API which allows developers to create blockchain-enabled applications quickly and easily using the tools they are familiar with. Developers can create Bitcoin, Syscoin and ZCash enabled applications without learning new languages as in the case of Ethereum and Hyperledger. The Syscoin API has been developed to make blockchain development quick and easy. Blockchain Foundry are continuing development on the API to enable custom smart contracts for nearly any use-case. Blockmarket Web will be fully build upon the functions the API is caple of.
