JSON RPC API

JSON is a lightweight data-interchange format. It can represent numbers, strings, ordered sequences of values, and collections of name/value pairs.

JSON-RPC is a stateless, light-weight remote procedure call (RPC) protocol. Primarily this specification defines several data structures and the rules around their processing. It is transport agnostic in that the concepts can be used within the same process, over sockets, over HTTP, or in many various message passing environments. It uses JSON (RFC 4627) as data format.

JSON-RPC Endpoint

Default JSON-RPC endpoints:

Client URL
Node http://localhost:{port}

Port must be defined explicitly by passing the number through the environment variable JSON_RPC_SERVER_PORT

Node

JSON_RPC_SERVER_PORT=3334 npm run commands

Environment Variables

Variable Mandatory Default Value Description
JSON_RPC_SERVER_HOST No 127.0.0.1 The IP address on which the server will listen
JSON_RPC_SERVER_PORT Yes {no-value} The Port on which the server will listen (if not defined, the server will not start)
JSON_RPC_BASIC_AUTH_ENABLE No False Whether the basic authentication is enabled or not
JSON_RPC_BASIC_AUTH_USER No {no-value} The basic authentication username
JSON_RPC_BASIC_AUTH_PASS No {no-value} The basic authentication password
JSON_RPC_RATE_LIMIT_WINDOW No 60000 The Rate limiter window (1 minute, 60 * 1000ms)
JSON_RPC_RATE_LIMIT_MAX_REQUESTS No 60 The Rate limiter maximum requests in the specified window
JSON_RPC_RATE_LIMIT_ENABLE No True Whether the Rate limiter is enabled or not

Curl Examples Explained

The curl options below might return a response where the node complains about the content type, this is because the --data option sets the content type to application/x-www-form-urlencoded . If your node does complain, manually set the header by placing -H "Content-Type: application/json" at the start of the call.

The examples also do not include the URL/IP & port combination which must be the last argument given to curl e.x. 127.0.0.1:3334
