query(view_state) - NEAR Protocol

Example code for the query(view_state) json-rpc method. Сomplete guide on how to use query(view_state) json-rpc in GetBlock.io Web3 documentation.

This method returns the key-value pairs stored in a smart contract’s on-chain state. It allows developers to read contract data, inspect stored variables, or analyse application states directly from the NEAR blockchain.

Supported Networks

• Mainnet

Parameters

Parameter	Type	Required	Description
request_type	string	Yes	Must be set to "view_state".
finality	string	Yes	Defines data consistency: "final", "near-final" or "optimistic". Default is "final".
account_id	string	Yes	The NEAR account ID that owns the contract.
prefix_base64	string	Optional	Base64-encoded key prefix filter. Returns only matching keys (use "" to fetch all).

Response Parameters Definition

Field	Type	Description
block_height	integer	Height of the block from which the state was retrieved.
block_hash	string	Hash of the block containing the contract state.
values	array	List of key-value pairs stored in the contract’s state.
values.key	string	Base64-encoded storage key.
values.value	string	Base64-encoded value associated with the key.

Use Cases

• Get contract-level configuration for analytics or dashboards.

• Debug smart contract storage during development or audits.

• Build indexers or off-chain data sync tools.

Code Example

Node(Axios)

import axios from 'axios';
let data = JSON.stringify({
  "jsonrpc": "2.0",
  "method": "query",
  "params": {
    "request_type": "view_state",
    "finality": "final",
    "account_id": "kiln.poolv1.nea",
    "prefix_base64": ""
  },
  "id": "getblock.io"
});

let config = {
  method: 'post',
  maxBodyLength: Infinity,
  url: 'https://go.getblock.io/<ACCESS_TOKEN>',
  headers: { 
    'Content-Type': 'application/json'
  },
  data : data
};

axios.request(config)
.then((response) => {
  console.log(JSON.stringify(response.data));
})
.catch((error) => {
  console.log(error);
});

Python(Requests)

import requests
import json

url = "https://go.getblock.io/<ACCESS_TOKEN>"

payload = json.dumps({
  "jsonrpc": "2.0",
  "method": "query",
  "params": {
    "request_type": "view_state",
    "finality": "final",
    "account_id": "kiln.poolv1.nea",
    "prefix_base64": ""
  },
  "id": "getblock.io"
})
headers = {
  'Content-Type': 'application/json'
}

response = requests.request("POST", url, headers=headers, data=payload)

print(response.text)

Error Handling

HTTP Code	Error Message	Description
400 Bad Request	UNKNOWN_ACCOUNT	The account ID format is incorrect.
500 Internal Server Error	Node processing error	The NEAR node encountered an issue retrieving state.
403 Forbidden	RBAC: access denied	The Getblock access token is missing or incorrect

Integration with Web3

By integrating query(view_state) into dApp, developers can:

• Read contract data directly without calling view functions.

• Build state inspection tools and dApp dashboards.

• Automate off-chain synchronization for analytics and monitoring.

• Create AI agents that interpret blockchain data dynamically.
