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:

{
"jsonrpc": "2.0",
"id": "dontcare",
"method": "query",
"params": {
"request_type": "view_access_key",
"finality": "final",
"account_id": "client.chainlink.testnet",
"public_key": "ed25519:H9k5eiU4xXS3M4z8HzKJSLaZdqGdGwBG49o7orNC4eZW"
}
}
Example response:

{
"jsonrpc": "2.0",
"result": {
"nonce": 85,
"permission": {
"FunctionCall": {
"allowance": "18501534631167209000000000",
"receiver_id": "client.chainlink.testnet",
"method_names": ["get_token_price"]
}
},
"block_height": 19884918,
"block_hash": "GGJQ8yjmo7aEoj8ZpAhGehnq9BSWFx4xswHYzDwwAP2n"
},
"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 view_access_key request type:

ERROR_TYPE
error.name
ERROR_CAUSE
error.cause.name
ReasonSolution
HANDLER_ERRORUNKNOWN_BLOCKThe 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_ACCOUNTThe requested account_id is invalid
  • Provide a valid account_id
UNKNOWN_ACCOUNTThe 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_KEYThe 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_SHARDThe 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_BLOCKSThe 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_ERRORPARSE_ERRORPassed 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_ERRORINTERNAL_ERRORSomething 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

View access key list

Returns all access keys for a given account.
