Network

The RPC API enables you to query status information for nodes and validators.

---

Node Status

Returns general status of a given node (sync status, nearcore node version, protocol version, etc), and the current set of validators.

• method: status
• params: []

Example:

JSON

{
  "jsonrpc": "2.0",
  "id": "dontcare",
  "method": "status",
  "params": []
}

JavaScript

const response = await near.connection.provider.status();

HTTPie

http post https://rpc.testnet.near.org jsonrpc=2.0 method=status params:='[]' id=dontcare

What could go wrong?

When API request fails, RPC server returns a structured error response with a limited number of well-defined error variants, so client code can exhaustively handle all the possible error cases. Our JSON-RPC errors follow verror convention for structuring the error response:

{
    "error": {
        "name": <ERROR_TYPE>,
        "cause": {
            "info": {..},
            "name": <ERROR_CAUSE>
        },
        "code": -32000,
        "data": String,
        "message": "Server error",
    },
    "id": "dontcare",
    "jsonrpc": "2.0"
}

Heads up

The fields code, data, and message in the structure above are considered legacy ones and might be deprecated in the future. Please, don't rely on them.

Here is the exhaustive list of the error variants that can be returned by status method:

ERROR_TYPE error.name	ERROR_CAUSE error.cause.name	Status Code	Reason	Solution
INTERNAL_ERROR	INTERNAL_ERROR	500	Something went wrong with the node itself or overloaded	Try again later Send a request to a different node Check error.cause.info for more details

Validation Status

Queries active validators on the network returning details and the state of validation on the blockchain.

• method: validators
• params: ["block hash"], [block number], {"epoch_id": "epoch id"}, {"block_id": block number}, {"block_id": "block hash"}, or [null] for the latest block

Note: If you want the latest block hash, block number and epoch id, you will need to query from the last block in an epoch. You can also query validators endpoint for past epochs if you input block hash, block number or epoch id of the past epoch that you want.

Example:

input: [block number]

What could go wrong?

When API request fails, RPC server returns a structured error response with a limited number of well-defined error variants, so client code can exhaustively handle all the possible error cases. Our JSON-RPC errors follow verror convention for structuring the error response:

{
    "error": {
        "name": <ERROR_TYPE>,
        "cause": {
            "info": {..},
            "name": <ERROR_CAUSE>
        },
        "code": -32000,
        "data": String,
        "message": "Server error",
    },
    "id": "dontcare",
    "jsonrpc": "2.0"
}

Heads up

The fields code, data, and message in the structure above are considered legacy ones and might be deprecated in the future. Please, don't rely on them.

Here is the exhaustive list of the error variants that can be returned by validators method:

ERROR_TYPE error.name	ERROR_CAUSE error.cause.name	Status Code	Reason	Solution
HANDLER_ERROR	UNKNOWN_EPOCH	200	An epoch for the provided block can't be found in a database	Check that the requested block is legit If the block had been produced more than 5 epochs ago, try to send your request to an archival node Check that the requested block is the last block of some epoch
REQUEST_VALIDATION_ERROR	PARSE_ERROR	400	Passed arguments can't be parsed by JSON RPC server (missing arguments, wrong format, etc.)	Check the arguments passed and pass the correct ones Check error.cause.info for more details
INTERNAL_ERROR	INTERNAL_ERROR	500	Something went wrong with the node itself or overloaded	Try again later Send a request to a different node Check error.cause.info for more details
