JSON RPC documentation

JSON RPC API Specification & Guideline

This page provides full documentation for the PascalCoin JSON-RPC API.

NOTE: There is a full C# wrapper for this API called NPascalCoin suitable for mobile and enterprise integrations.

Contents

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.

Introduction

In order to work properly with Pascal Coin, you must follow these instructions:

JSON RPC Standard 2.0

PascalCoin uses (by default) the pure JSON RPC 2.0 standard

This means that:

  • Every call MUST include 3 params: {"jsonrpc": "2.0", "method": "XXX", "id": YYY}
    • jsonrpc : String value = "2.0"
    • method : String value, name of the method to call
    • id : Integer value
  • Optionally can contain another param called "params" holding an object. Inside we will include params to send to the method
    • {"jsonrpc": "2.0", "method": "XXX", "id": YYY, "params":{"p1":" ","p2":" "}}
  • If JSON is not JSON RPC Standard 2.0 compliant, it will be rejected without a response.
  • If JSON does not have a valid "id" value it will not be processed and rejected without a response.

HTTP POST Details

All calls will be using HTTP protocol (HTTP 1.1) and passing JSON calls by POST at port 4003

  • Protocol: HTTP v1.1
  • Port: 4003
  • Http method: POST

Example

// Request to server at localhost. Method "getblockcount" (Returns block count of the PascalCoin network)
curl -X POST --data '{"jsonrpc":"2.0","method":"getblockcount","id":123}' http://localhost:4003

// Result
{
  "jsonrpc":"2.0",
  "id":123,
  "result": 26724
}

Data Types

RPC Calls could include/return these data types:

  • Integers, strings, boolean (true or false) or null
  • HEXASTRING: String that contains an hexadecimal value (ex. "4423A39C"). An hexadecimal string is always an even character length.
  • PASCURRENCY: Pascal Coin currency is a maximum 4 decimal number (ex. 12.1234). Decimal separator is a "." (dot)
  • JSON "specific" Objects: List of some objects returned by RPC calls and used for many methods: (See each method to know which object returns)

Account Object

An "Account object" is a JSON object with information about an account. Fields are:

  • account : Integer - Account number
