# NULS API-JSONRPC

NULS customized the NULS2.0 wallet version required for docking. The docking wallet embeds the NULS-API module. The module encapsulates the NULS-SDK function, uses the HTTP protocol to access the interface, and supports JSON-RPC and RESTful two formats.

mainnet and test wallet download address

NULS-API offline operation tool download address

# Settings

The default port number for the NULS-API module is 18004, which can be modified in the nuls.ncf configuration file (for the entire wallet chainbox) or the module.ncf configuration file (for the individual module), as follows:

[nuls-API]
#httpServerStart port
serverPort=18004

# Description

In order to better understand the related business of NULS2.0, and the meaning of the return value of the interface, do some explanation here in advance.

# Online & Offline

The nuls-api module provides several online and offline interfaces.

Online interface: The wallet must operate normally and be able to connect to other nodes in the network to properly synchronize blocks and broadcast data. Before calling the online interface, it is best to sync to the latest block. The data generated by the interface is saved in the wallet. For example, create an account, change a password, transfer money, get a block header, and so on.

Offline interface: NULS 2.0 provides a NULS-API tool for offline operation .No need to install a wallet, you can run independently on a server that is not connected to the network.The user receives the relevant parameters by calling the offline interface, and obtains the return value, and the corresponding data is not stored in the wallet.For example, creating an account offline, offline assembly transfer transactions, offline signatures, and the like.

# interface method -- JSON call details

json-rpc access method Example json data request:

{
  "jsonrpc":"2.0",
  "method": "methodCMD", //interface name
  "params":[], //All interface parameters are passed as arrays, and the order of the parameters cannot be changed. If the parameters are not required, they must also be filled in null placeholders.
  "id":1234
}

Usage example using linux command curl, issued to a chainbox instance.:


\> curl -s -X POST -H 'Content-Type: application/json' --data '{"jsonrpc":"2.0","method":"getChainInfo","params”:[], “id":1234}' http://127.0.0.1:18003

{"jsonrpc":"2.0","id":"null","result":{"chainId":2,"chainName":"nuls2","defaultAsset":{"key":"2-1","chainId":2,"assetId":1,"symbol":"NULS","decimals":8,"initCoins":0,"address":null,"status":1},"assets":[{"key":"2-1","chainId":2,"assetId":1,"symbol":"NULS","decimals":8,"initCoins":0,"address":null,"status":1}],"seeds":["tNULSeBaMkrt4z9FYEkkR9D6choPVvQr94oYZp"],"status":1,"new":false}}

When using Postman:

Type the URL of the API (http://127.0.0.1:18003)
Change method to POST.
In the parameter section click on "raw" and select format as "JSON" and add the json request in the testarea provided.
In the headers section add "Content-Type" as header and "application/json;charset=UTF-8" as the value.
Test by comparing the output to the curl output.

# RESTful access method

Add request header Content-Type: application/json;charset=UTF-8

For the REST access method, please refer to the RESTFUL interface documentation.

# Interface debugging

# Field Description

chain's chainId:

NULS2.0 supports multi-chain parallel and cross-chain transfer. Each chain is distinguished by chain id. The chain id of the nuls main network is 1, and the chain id of the nuls test network is 2.

Chain assets:

NULS2.0 supports each chain in addition to the default assets, dynamically add assets according to business needs. Each asset of each chain is distinguished by a composite primary key of the chain ID and the asset ID. For example, NULS of the NULS main network, chainId=1, assetId=1

Type value of the transaction:

NULS2.0 has multiple transactions by default. Each transaction has different functions. When calling the interface to query the transaction details, the type field can be used to distinguish different transaction types. The following are the enumeration values of the transaction type:

int COIN_BASE = 1;						// coinBase block reward
int TRANSFER = 2;						// transfer
int ACCOUNT_ALIAS = 3;					/ / Set the account alias
int REGISTER_AGENT = 4;					// New consensus node
int DEPOSIT = 5;						// Entrusted to participate in the consensus
int CANCEL_DEPOSIT = 6;					// cancel the delegate consensus
int YELLOW_PUNISH = 7;					// yellow card
int RED_PUNISH = 8;						// red card
int STOP_AGENT = 9;						// Unregister the consensus node
int CROSS_CHAIN = 10;					// Cross-chain transfer
int REGISTER_CHAIN_AND_ASSET = 11;		// registration chain
int DESTROY_CHAIN_AND_ASSET = 12;		// Logout chain
int ADD_ASSET_TO_CHAIN = 13;			// Add an asset to the chain
int REMOVE_ASSET_FROM_CHAIN = 14;		// Delete the assets on the chain
int CREATE_CONTRACT = 15;				// Create a smart contract
int CALL_CONTRACT = 16;					/ / Call smart contract
int DELETE_CONTRACT = 17;				// delete the smart contract
int CONTRACT_TRANSFER = 18;				// Internal transfer of the contract
int CONTRACT_RETURN_GAS = 19;			// Contract execution fee refund
int CONTRACT_CREATE_AGENT = 20;			// contract new consensus node
int CONTRACT_DEPOSIT = 21;				// Contract commissioned to participate in the consensus
int CONTRACT_CANCEL_DEPOSIT = 22;		// Contract cancellation commission consensus
int CONTRACT_STOP_AGENT = 23;			// Contract cancellation consensus node
int VERIFIER_CHANGE = 24;				// certifier change

From and to: of the transaction

Take a transfer transaction as an example: tx.type = 2

From is the transferor of the transfer transaction, each from a certain amount of assets transferred as a transferor, wherein the nonce value will change after each transfer, you can get the current latest nonce value by calling the query account balance interface.

To is the recipient of the transfer transaction, each to is regarded as the recipient receives the amount of an asset, where lockTime is the lock time. When the lock time is greater than 0, it means that the real time exceeds this value, the asset can be used normally; when lockTime = -1, it means permanent lock, special transaction is needed to unlock, such as participation in the consensus and cancellation of the consensus . Transaction fee = the sum of the main assets of the chain - the sum of the main assets of the chain
