Example response

{
  "jsonrpc": "2.0",
  "result": {
    "nonce": 187310139000001,
    "permission": "FullAccess",
    "block_hash": "56xEo2LorUFVNbkFhCncFSWNiobdp1kzm14nZ47b5JVW",
    "block_height": 187440904
  },
  "id": "dontcare"
}

For a function-call key, permission is an object instead of the "FullAccess" string:

"permission": {
  "FunctionCall": {
    "allowance": "250000000000000000000000",
    "receiver_id": "contract.rpc-examples.testnet",
    "method_names": ["get_greeting"]
  }
}

For a gas key, permission also carries the key’s prepaid balance and number of nonce lanes (num_nonces). A full-access gas key uses GasKeyFullAccess:

"permission": {
  "GasKeyFullAccess": {
    "balance": "5000000000000000000000000",
    "num_nonces": 8
  }
}

A function-call gas key uses GasKeyFunctionCall, which is a flat object carrying the same function-call restrictions (allowance, receiver_id, method_names) as FunctionCall, alongside the gas-key balance and num_nonces:

"permission": {
  "GasKeyFunctionCall": {
    "balance": "5000000000000000000000000",
    "num_nonces": 8,
    "allowance": "250000000000000000000000",
    "receiver_id": "contract.rpc-examples.testnet",
    "method_names": ["get_greeting"]
  }
}

The nonces of the individual lanes are not included — query them with view_gas_key_nonces.

For a post-quantum ml-dsa-65 key, pass the full ml-dsa-65: public key in public_key. The network hashes it to locate the on-chain entry, so you query it exactly like an ed25519 or secp256k1 key.

View Access Key List

Returns the access keys of an account, each with its nonce and permissions.

method: query
params: request_type: view_access_key_list, finality OR block_id, account_id, optional limit, optional after_key

From nearcore 2.14.0, a request without limit or after_key fails with TOO_MANY_ACCESS_KEYS if the account has more than 100 keys (the default limit). Use pagination for such accounts. See Paginate the key list.

  },
  "id": "dontcare"
}

Post-quantum ml-dsa-65 keys are stored on-chain by hash, so they appear here with an ml-dsa-65-hash: prefix (a base58-encoded 32-byte SHA3-256 digest) rather than the full ml-dsa-65: key. To match an entry to one of your own keys, derive its handle — the SHA3-256 of the domain-separation tag near:ml-dsa-65-pubkey-hash:v1 followed by the raw public key — and compare it against the returned value (hashing the key without that prefix will not match).

Paginate the key list

Pagination example

Request the first page with limit:

{
  "jsonrpc": "2.0",
  "id": "dontcare",
  "method": "query",
  "params": {
    "request_type": "view_access_key_list",
    "finality": "final",
    "account_id": "account.rpc-examples.testnet",
    "limit": 1
  }
}

The response has last_key when more keys remain:

{
  "jsonrpc": "2.0",
  "result": {
    "keys": [
      {
        "public_key": "ed25519:DCkbTMS8s4kqV4nGvz5kRBdNbY9YwjjvNGNXKpAg2eFa",
        "access_key": {
          "nonce": 187310139000001,
          "permission": "FullAccess"
        }
      }
    ],
    "last_key": "ed25519:DCkbTMS8s4kqV4nGvz5kRBdNbY9YwjjvNGNXKpAg2eFa",
    "block_hash": "56xEo2LorUFVNbkFhCncFSWNiobdp1kzm14nZ47b5JVW",
    "block_height": 187440904
  },
  "id": "dontcare"
}

Request the next page with after_key set to that last_key. To read every page from the same state, also replace finality with block_id set to the block_hash of the first response:

{
  "jsonrpc": "2.0",
  "id": "dontcare",
  "method": "query",
  "params": {
    "request_type": "view_access_key_list",
    "block_id": "56xEo2LorUFVNbkFhCncFSWNiobdp1kzm14nZ47b5JVW",
    "account_id": "account.rpc-examples.testnet",
    "after_key": "ed25519:DCkbTMS8s4kqV4nGvz5kRBdNbY9YwjjvNGNXKpAg2eFa",
    "limit": 1
  }
}

A response without last_key is the last page.

Rule	Details
Keys per response	At most `view_access_keys_limit`, which is 100 by default. Node operators can change it. A larger `limit` is lowered to this value.
Request without `limit` or `after_key`	Fails with `TOO_MANY_ACCESS_KEYS` if the account has more keys than `view_access_keys_limit`.
Version	From nearcore 2.14.0. Nodes on nearcore 2.13 return all keys in one response and ignore `limit` and `after_key`.

View Gas Key Nonces

Returns the current nonce of every parallel nonce lane of a gas key, given the account and the key’s public key. The array is indexed by nonce_index: the first element is lane 0, the second is lane 1, and so on. Use view_access_key to see the gas key’s balance and permission.

  "id": "dontcare"
}

Each lane starts at block_height * 10^6 from when the key was added and advances independently as transactions use it.

Querying a key that exists but is not a gas key (or does not exist at all) returns an UnknownGasKey error.

View Contract State

Returns the state (key-value pairs) of a contract based on a key prefix (base64 encoded). Pass an empty string for prefix_base64 to return the entire state.

method: query
params: request_type: view_state, finality OR block_id, account_id, prefix_base64, optional limit, optional after_key_base64, optional include_proof

By default, a node rejects a view_state request with TOO_LARGE_CONTRACT_STATE if the account’s state is above 50,000 bytes. A narrower prefix_base64 does not avoid the error. To read a large state, use pagination. See Paginate the state.

Pagination example

Request the first page with limit:

  "jsonrpc": "2.0",
  "id": "dontcare",
  "method": "query",
  "params": {
    "request_type": "view_state",
    "finality": "final",
    "account_id": "contract.rpc-examples.testnet",
    "prefix_base64": "",
    "limit": 2
  }
}

The response has last_key when more entries remain. Keys and values are base64:

{
  "jsonrpc": "2.0",
  "result": {
    "values": [
      { "key": "YQ==", "value": "MQ==" },
      { "key": "Yg==", "value": "Mg==" }

    "last_key": "Yg==",
    "block_hash": "56xEo2LorUFVNbkFhCncFSWNiobdp1kzm14nZ47b5JVW",
    "block_height": 187440904
  },
  "id": "dontcare"
}

Request the next page with after_key_base64 set to that last_key. To read every page from the same state, also replace finality with block_id set to the block_hash of the first response:

{
  "jsonrpc": "2.0",
  "id": "dontcare",
  "method": "query",
  "params": {
    "request_type": "view_state",
    "block_id": "56xEo2LorUFVNbkFhCncFSWNiobdp1kzm14nZ47b5JVW",

    "prefix_base64": "",
    "after_key_base64": "Yg==",
    "limit": 2
  }
}

A response without last_key is the last page.

A request without limit or after_key_base64 is checked against the size of the whole account. This size is the account’s storage usage without the contract code, so a narrower prefix_base64 does not avoid the error. Paginated requests skip this check.

Rule	Details
Request without `limit` or `after_key_base64`	Fails with `TOO_LARGE_CONTRACT_STATE` if the account’s state is above `trie_viewer_state_size_limit`. The default is 50,000 bytes, and the node operator can change it.
Items per page	At most 10,000. A larger `limit` is lowered to 10,000.
Bytes per page	The node stops adding items once the keys and values of the page reach 50,000 bytes. The last item can make a page larger than that.
`after_key_base64`	After decoding, the key must start with the decoded `prefix_base64`. The base64 strings themselves do not have to match. Otherwise the node returns `INTERNAL_ERROR`.
`include_proof`	Cannot be combined with `limit` or `after_key_base64`. If it is, the node returns `INTERNAL_ERROR`.
Version	`limit` and `after_key_base64` are available from nearcore 2.13.0.

http POST https://rpc.testnet.near.org \

  params:='{"request_type":"call_function","finality":"final","account_id":"contract.rpc-examples.testnet","method_name":"get_greeting","args_base64":""}'

Decode the result

A call_function query returns the contract’s serialized return value as an array of bytes. Decode those bytes as UTF-8 and parse as JSON. For example, [34, 104, 101, 108, 108, 111, 34] decodes to the JSON string "hello".

// Decoding a call_function result
JSON.parse(Buffer.from(response.result.result).toString("utf8"));

Transaction return values

Transaction and receipt outcomes encode successful return values in the base64 string status.SuccessValue. Decode that string, then parse it if the method returns JSON. An empty SuccessValue indicates no return value. Inspect Failure as an execution error. With a full transaction RPC response saved as response.json:

node -e '
const response = JSON.parse(require("node:fs").readFileSync("response.json", "utf8"));
const status = response.result.status;
if ("SuccessValue" in status) {
  console.log(status.SuccessValue === "" ? undefined :
    JSON.parse(Buffer.from(status.SuccessValue, "base64").toString("utf8")));
} else {
  console.log(status);
}
'

Error Handling

Query errors come back in four ways. Check for an error object first, and then for result.error.

Request errors

If the node cannot parse the request parameters, it returns an error with error.name set to REQUEST_VALIDATION_ERROR and error.cause.name set to PARSE_ERROR. This happens, for example, when args_base64 is not valid base64.

Internal errors

If the node fails internally, it returns an error with error.name set to INTERNAL_ERROR. The message is in error.cause.info.error_message. view_state also answers this way when include_proof is combined with pagination, or when after_key_base64 is outside the prefix.

Handler errors

For the errors below, the response has error.name set to HANDLER_ERROR and error.cause.name set to the listed value. For example:

{
  "jsonrpc": "2.0",
  "error": {
    "name": "HANDLER_ERROR",
    "cause": {
      "name": "TOO_LARGE_CONTRACT_STATE",
      "info": {
        "contract_account_id": "contract.rpc-examples.testnet",
        "block_height": 187440904,
        "block_hash": "56xEo2LorUFVNbkFhCncFSWNiobdp1kzm14nZ47b5JVW"
      }
    },
    "code": -32000,
    "message": "Server error",
    "data": "State of contract contract.rpc-examples.testnet is too large to be viewed"
  },
  "id": "dontcare"
}

`error.cause.name`	Description	Solution
`UNKNOWN_ACCOUNT`	Account does not exist	Check account ID spelling
`INVALID_ACCOUNT`	Invalid account format	Use valid account ID (e.g., `account.near`)
`UNKNOWN_BLOCK`	Block not found	Use a valid block hash or height
`UNKNOWN_GAS_KEY`	Key is not a gas key or does not exist	Check the public key and that it was added as a gas key
`GARBAGE_COLLECTED_BLOCK`	Block too old	Use archival node or more recent block
`NO_CONTRACT_CODE`	No contract deployed (returned by `view_code`)	Verify the account has a deployed contract
`NO_GLOBAL_CONTRACT_CODE`	No global contract for this code hash or account	Check the code hash or the publishing account ID
`TOO_LARGE_CONTRACT_STATE`	Account state is above the node’s `view_state` limit	Paginate with `limit` and `after_key_base64`
`TOO_MANY_ACCESS_KEYS`	Account has more keys than one response can hold	Paginate with `limit` and `after_key`

Errors in the result

A view function call that fails while the contract runs does not return an error object. The node answers with HTTP status 200, and result.error holds a text message:

{
  "jsonrpc": "2.0",
  "result": {
    "block_hash": "56xEo2LorUFVNbkFhCncFSWNiobdp1kzm14nZ47b5JVW",
    "block_height": 187440904,
    "error": "wasm execution failed with error: MethodResolveError(MethodNotFound)",
    "logs": []
  },
  "id": "dontcare"
}

Check result.error before you decode result.result. view_access_key for a key that does not exist answers the same way. Common messages:

The method does not exist: wasm execution failed with error: MethodResolveError(MethodNotFound).
The account has no contract: the message starts with wasm execution failed with error: CompilationError(CodeDoesNotExist.
