Access Keys

View access key

Returns information about a single access key for given account.

If permission of the key is FunctionCall, it will return more details such as the allowance, receiver_id, and method_names.

  • method: query
  • params:
    • request_type: view_access_key
    • finality OR block_id
    • account_id: "example.testnet"
    • public_key: "example.testnet's public key"

Example:


“`json
{
“jsonrpc”: “2.0”,
“id”: “dontcare”,
“method”: “query”,
“params”: {
“request_type”: “view_access_key”,
“finality”: “final”,

“public_key”: “ed25519:H9k5eiU4xXS3M4z8HzKJSLaZdqGdGwBG49o7orNC4eZW”
}
}
“`


“`js
const response = await near.connection.provider.query({

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 view_access_key request type:

ERROR_TYPE
error.name 		ERROR_CAUSE
error.cause.name		 Reason Solution
HANDLER_ERROR UNKNOWN_BLOCK The requested block has not been produced yet or it has been garbage-collected (cleaned up to save space on the RPC node)
  • 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
INVALID_ACCOUNT The requested account_id is invalid
  • Provide a valid account_id
UNKNOWN_ACCOUNT The requested account_id has not been found while viewing since the account has not been created or has been already deleted
  • Check the account_id
  • Specify a different block or retry if you request the latest state
UNKNOWN_ACCESS_KEY The requested public_key has not been found while viewing since the public key has not been created or has been already deleted
  • Check the public_key
  • Specify a different block or retry if you request the latest state
UNAVAILABLE_SHARD The node was unable to found the requested data because it does not track the shard where data is present
  • Send a request to a different node which might track the shard
NO_SYNCED_BLOCKS The node is still syncing and the requested block is not in the database yet
  • Wait until the node finish syncing
  • Send a request to a different node which is synced
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
