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 Data format

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

JSON RPC standard 2.0

We use (by default) 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 calls

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
enc_pubkey : HEXASTRING - Encoded public key value (See decodepubkey )
balance : PASCURRENCY - Account balance
n_operation : Integer - Operations made by this account (Note: When an account receives a transaction, n_operation is not changed)
updated_b Integer - Last block that updated this account. If equal to blockchain blocks count it means that it has pending operations to be included to the blockchain

Block Object

A "Block object" is a JSON object with information about a Blockchain's block. Fields are:

block : Integer - Block number
enc_pubkey : HEXASTRING - Encoded public key value used to init 5 created accounts of this block (See decodepubkey )
reward : PASCURRENCY - Reward of first account's block
fee : PASCURRENCY - Fee obtained by operations
ver : Integer - Pascal Coin protocol used
ver_a : Integer - Pascal Coin protocol available by the miner
timestamp : Integer - Unix timestamp
target : Integer - Target used
nonce : Integer - Nonce used
payload : String - Miner's payload
sbh : HEXASTRING - SafeBox Hash
oph : HEXASTRING - Operations hash
pow : HEXASTRING - Proof of work
operations : Integer - Number of operations included in this block
hashratekhs : Integer - Estimated network hashrate calculated by previous 50 blocks average
maturation : Integer - Number of blocks in the blockchain higher than this

Operation Object

An "Operation object" is a JSON object with information about an operation. Fields are:

block : Integer - Block number
opblock : Integer - Operation index inside a block (0..operations-1). Note: If opblock=-1 means that is a blockchain reward
optype : Integer - Operation type. can be:
- 0 = Blockchain reward
- 1 = Transaction
- 2 = Change key
- 3 = Recover founds (lost keys)
time : Integer - Block timestamp
account : Integer - Account affected by this operation. Note: A transaction has 2 affected accounts.
optxt : String - Human readable operation type
amount : PASCURRENCY - Amount of coins transferred from sender_account to dest_account (Only apply when optype=1)
fee : PASCURRENCY - Fee of this operation
balance : PASCURRENCY - Balance of account after this block is introduced in the Blockchain
- Note: balance is a calculation based on current safebox account balance and previous operations, it's only returned on pending operations and account operations
sender_account : Integer - Sender account in a transaction (optype = 1)
dest_account : Integer - Destination account in a transaction (optype = 1)
enc_pubkey : HEXASTRING - Encoded public key in a change key operation (optype = 2). See decodepubkey
ophash : HEXASTRING - Operation hash used to find this operation in the blockchain

Connection Object

A "Connection object" is a JSON object with a connection to other node information

server : Boolean - True if this connection is to a server node. False if this connection is a client node
ip : String
port : Integer
secs : Integer - seconds of live of this connection
sent : Integer - Bytes sent
recv : Integer - Bytes received
appver : String - Other node App version
netvar : Integer - Net protocol of other node
netvar_a : Integer - Net protocol available of other node

Error codes

JSON-RPC Error codes will be in a JSON-Object in this format:

code : Integer - Error code
message : String - Human readable error description

List of usual error codes

100 - Internal error
1001 - Method not found
1002 - Invalid account
1003 - Invalid block
1004 - Invalid operation
1005 - Invalid public key
1010 - Not found
1015 - Wallet is password protected
