API

Tip

This page was generated by a plugin that directly references this file in the AvalancheGo GitHub repository.

This API allows clients to interact with the P-Chain, which maintains Avalanche's validator set and handles blockchain creation.

Endpoint

/ext/bc/P

Format

This API uses the json 2.0 RPC format.

Methods

`platform.exportKey`

Caution

Deprecated as of v1.9.12.

Warning

Not recommended for use on Mainnet. See warning notice in Keystore API.

Get the private key that controls a given address.

Signature:

platform.exportKey({
    username: string,
    password: string,
    address: string
}) -> {privateKey: string}

username is the user that controls address.
password is username‘s password.
privateKey is the string representation of the private key that controls address.

Example Call:

curl -X POST --data '{
    "jsonrpc":"2.0",
    "id"     :1,
    "method" :"platform.exportKey",
    "params" :{
        "username" :"myUsername",
        "password": "myPassword",
        "address": "P-avax18jma8ppw3nhx5r4ap8clazz0dps7rv5ukulre5"
    }
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/bc/P

Example Response:

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "privateKey": "PrivateKey-Lf49kAJw3CbaL783vmbeAJvhscJqC7vi5yBYLxw2XfbzNS5RS"
  }
}

`platform.getBalance`

Caution

Deprecated as of v1.9.12.

Get the balance of AVAX controlled by a given address.

Signature:

platform.getBalance({
    addresses: []string
}) -> {
    balances: string -> int,
    unlockeds: string -> int,
    lockedStakeables: string -> int,
    lockedNotStakeables: string -> int,
    utxoIDs: []{
        txID: string,
        outputIndex: int
    }
}

addresses are the addresses to get the balance of.
balances is a map from assetID to the total balance.
unlockeds is a map from assetID to the unlocked balance.
lockedStakeables is a map from assetID to the locked stakeable balance.
lockedNotStakeables is a map from assetID to the locked and not stakeable balance.
utxoIDs are the IDs of the UTXOs that reference address.

Example Call:

curl -X POST --data '{
  "jsonrpc":"2.0",
  "id"     : 1,
  "method" :"platform.getBalance",
  "params" :{
      "addresses":["P-custom18jma8ppw3nhx5r4ap8clazz0dps7rv5u9xde7p"]

`platform.getBlockchainStatus`

Get the status of a blockchain.

Signature:

platform.getBlockchainStatus(
    {
        blockchainID: string
    }
) -> {status: string}

status is one of:

Validating: The blockchain is being validated by this node.
Created: The blockchain exists but isn't being validated by this node.
Preferred: The blockchain was proposed to be created and is likely to be created but the transaction isn't yet accepted.
Syncing: This node is participating in this blockchain as a non-validating node.
Unknown: The blockchain either wasn't proposed or the proposal to create it isn't preferred. The proposal may be resubmitted.

Example Call:

curl -X POST --data '{

`platform.getSubnets`

Caution

Deprecated as of v1.9.12.

Get info about the Avalanche L1s.

Signature:

platform.getSubnets({
    ids: []string
}) ->
{
    subnets: []
        id: string,
        controlKeys: []string,
        threshold: string
    }
}

ids are the IDs of the Avalanche L1s to get information about. If omitted, gets information about all Avalanche L1s.
id is the Avalanche L1's ID.
threshold signatures from addresses in controlKeys are needed to add a validator to the Avalanche L1. If the Avalanche L1 is a PoS Avalanche L1, then threshold will be 0 and controlKeys will be empty.

See here for information on adding a validator to a Avalanche L1.

`platform.getTxStatus`

Gets a transaction's status by its ID. If the transaction was dropped, response will include a reason field with more information why the transaction was dropped.

Signature:

platform.getTxStatus({
    txID: string
}) -> {status: string}

status is one of:

Committed: The transaction is (or will be) accepted by every node
Processing: The transaction is being voted on by this node
Dropped: The transaction will never be accepted by any node in the network, check reason field for more information
Unknown: The transaction hasn't been seen by this node

Example Call:

curl -X POST --data '{
    "jsonrpc": "2.0",
    "method": "platform.getTxStatus",
    "params": {
        "txID":"TAG9Ns1sa723mZy1GSoGqWipK6Mvpaj7CAswVJGM6MkVJDF9Q"
   },
    "id": 1
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/bc/P

Example Response:

{
  "jsonrpc": "2.0",
  "result": {
    "status": "Committed"
  },
  "id": 1
}

`platform.getUTXOs`

Gets the UTXOs that reference a given set of addresses.

Signature:

platform.getUTXOs(
    {
        addresses: []string,
        limit: int, // optional
        startIndex: { // optional
            address: string,
            utxo: string
        },
        sourceChain: string, // optional
        encoding: string, // optional
    },
) ->
{
    numFetched: int,
    utxos: []string,
    endIndex: {
        address: string,
        utxo: string
    },
    encoding: string,
}

utxos is a list of UTXOs such that each UTXO references at least one address in addresses.
At most limit UTXOs are returned. If limit is omitted or greater than 1024, it is set to 1024.
This method supports pagination. endIndex denotes the last UTXO returned. To get the next set of UTXOs, use the value of endIndex as startIndex in the next call.
If startIndex is omitted, will fetch all UTXOs up to limit.
When using pagination (that is when startIndex is provided), UTXOs are not guaranteed to be unique across multiple calls. That is, a UTXO may appear in the result of the first call, and then again in the second call.
When using pagination, consistency is not guaranteed across multiple calls. That is, the UTXO set of the addresses may have changed between calls.
encoding specifies the format for the returned UTXOs. Can only be hex when a value is provided.

Example

Suppose we want all UTXOs that reference at least one of P-avax18jma8ppw3nhx5r4ap8clazz0dps7rv5ukulre5 and P-avax1d09qn852zcy03sfc9hay2llmn9hsgnw4tp3dv6.

        "encoding": "hex"
    }

Since numFetched is less than limit, we know that we are done fetching UTXOs and don't need to call this method again.

Suppose we want to fetch the UTXOs exported from the X Chain to the P Chain in order to build an ImportTx. Then we need to call GetUTXOs with the sourceChain argument in order to retrieve the atomic UTXOs:

curl -X POST --data '{

`platform.getValidatorsAt`

Get the validators and their weights of an Avalanche L1 or the Primary Network at a given P-Chain height.

Signature:

platform.getValidatorsAt(
    {
        height: int,
        subnetID: string, // optional

)

height is the P-Chain height to get the validator set at.
subnetID is the Avalanche L1 ID (SubnetID) to get the validator set of. If not given, gets validator set of the Primary Network.

Example Call:
