# Platform Chain API

This API allows clients to interact with the
[P-Chain](/learn/avalanche/avalanche-platform.md#p-chain), which
maintains Avalanche’s [validator](/nodes/validate/how-to-stake#validators) set and handles
blockchain creation.

## Endpoint

```sh
/ext/bc/P
```

## Format

This API uses the `json 2.0` RPC format.

## Methods

### `platform.exportKey`

:::caution

Deprecated as of [**v1.9.12**](https://github.com/ava-labs/avalanchego/releases/tag/v1.9.12).

:::

:::warning

Not recommended for use on Mainnet. See warning notice in [Keystore API](/reference/avalanchego/keystore-api.md).

:::

Get the private key that controls a given address.

**Signature:**

```sh
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:**

```sh
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:**

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

### `platform.getBalance`

:::caution

Deprecated as of [**v1.9.12**](https://github.com/ava-labs/avalanchego/releases/tag/v1.9.12).

:::

Get the balance of AVAX controlled by a given address.

**Signature:**

```sh
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:**

```sh
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:**

```sh
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:**

```sh
curl -X POST --data '{
    "jsonrpc": "2.0",
    "method": "platform.getBlockchainStatus",
    "params":{
        "blockchainID":"2NbS4dwGaf2p1MaXb65PrkZdXRwmSX4ZzGnUu7jm3aykgThuZE"

### `platform.getStakingAssetID`

Retrieve an assetID for a Subnet’s staking asset.

**Signature:**

```sh
platform.getStakingAssetID({
    subnetID: string // optional
}) -> {
    assetID: string
}
```

- `subnetID` is the Subnet whose assetID is requested.
- `assetID` is the assetID for a Subnet’s staking asset.

**Example Call:**

```sh
curl -X POST --data '{
    "jsonrpc": "2.0",
    "method": "platform.getStakingAssetID",
    "params": {
        "subnetID": "11111111111111111111111111111111LpoYY"

### `platform.getSubnets`

:::caution

Deprecated as of [**v1.9.12**](https://github.com/ava-labs/avalanchego/releases/tag/v1.9.12).

:::

Get info about the Subnets.

**Signature:**

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

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

### `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:**

```sh
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:**

```sh
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:**

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

### `platform.getUTXOs`

Gets the UTXOs that reference a given set of addresses.

**Signature:**

```sh
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`.

```sh
curl -X POST --data '{
    "jsonrpc":"2.0",
    "id"     :1,
    "method" :"platform.getUTXOs",
    "params" :{
        "addresses":["P-avax18jma8ppw3nhx5r4ap8clazz0dps7rv5ukulre5", "P-avax1d09qn852zcy03sfc9hay2llmn9hsgnw4tp3dv6"],
        "limit":5,
        "encoding": "hex"
    }
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/bc/P
```

This gives response:

  },

}
```

Since `numFetched` is the same as `limit`, we can tell that there may be more UTXOs that were not
fetched. We call the method again, this time with `startIndex`:

```sh
curl -X POST --data '{
    "jsonrpc":"2.0",
    "id"     :1,
    "method" :"platform.getUTXOs",
    "params" :{

        "startIndex": {
            "address": "P-avax18jma8ppw3nhx5r4ap8clazz0dps7rv5ukulre5",

        },
        "encoding": "hex"
    }
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/bc/P

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:

```sh
curl -X POST --data '{
    "jsonrpc":"2.0",
    "id"     :1,
    "method" :"platform.getUTXOs",
    "params" :{
        "addresses":["P-avax18jma8ppw3nhx5r4ap8clazz0dps7rv5ukulre5"],
        "sourceChain": "X",
        "encoding": "hex"
    }
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/bc/P
```

This gives response:

```json
{
  "jsonrpc": "2.0",
  "result": {
    "numFetched": "1",
    "utxos": [
      "0x00001f989ffaf18a18a59bdfbf209342aa61c6a62a67e8639d02bb3c8ddab315c6fa0000000139c33a499ce4c33a3b09cdd2cfa01ae70dbf2d18b2d7d168524440e55d55008800000007000000746a528800000000000000000000000001000000013cb7d3842e8cee6a0ebd09f1fe884f6861e1b29cd704fe76"
