Node Status

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

“`json
{
“jsonrpc”: “2.0”,
“id”: “dontcare”,
“method”: “status”,
“params”: []
}
“`


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

“`bash
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		 Reason Solution
INTERNAL_ERROR INTERNAL_ERROR 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

Network Info

Returns the current state of node network connections (active peers, transmitted data, etc.)

  • method: network_info
  • params: none

Example:


“`json
{
“jsonrpc”: “2.0”,
“id”: “dontcare”,
“method”: “network_info”,
“params”: []
}
“`


“`bash
http post https://rpc.testnet.near.org jsonrpc=2.0 method=network_info params:='[]’ id=dontcare
“`


Example response:

“`json

“jsonrpc”: “2.0”,
“result”: {

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], or [null] for the latest block

Note: For ["block hash"] & [block number] you will need to query recent blocks as they become garbage collected after five epochs.

[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		 Reason Solution
HANDLER_ERROR UNKNOWN_EPOCH 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
REQUEST_VALIDATION_ERROR PARSE_ERROR 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 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
