If you are developing a service on Obyte and your programming language is node.js, your best option is to just require() the ocore modules that you need.
For exchanges and other custody wallets, there is a specialized JSON RPC service. However it is limited and exposes only those functions that the exchanges need.
If you are developing a service on Obyte and your programming language is node.js, your best option is to just require() the ocore modules that you need (most likely you need headless-obyte and various modules inside ocore). This way, you'll also be running a Obyte node in-process.
If you are programming in another language, or you'd like to run your Obyte node in a separate process, you can still access many of the functions of headless-obyte and ocoreby creating a thin RPC wrapper around the required functions and then calling them via JSON-RPC.
To get started, we can add RPCify to existing project or directly to headless-obyte with this command:
See the documentation about RPCify for more details.
Exposing functions and events
To expose the required functions via JSON-RPC, create a project that has headless-obyte, ocore (and any other ocore modules) and RPCify as dependencies:
var rpcify =require('rpcify');
var eventBus =require('ocore/event_bus.js');
// this is a module whose methods you want to expose via RPC
var headlessWallet =require('headless-obyte');// when headless-obyte is dependency of your project
//var headlessWallet = require('../start.js'); // when this script is in headless-obyte tools folder
var balances =require('ocore/balances.js');// another such module
// most of these functions become available only after the passphrase is entered
