# JSON-RPC API Methods

!!! danger "Breaking Change in v0.8.3"
    From v0.8.3, incoming HTTP requests are only accepted from hostnames specified using the [`--host-whitelist`](Using-JSON-RPC-API.md) option. 

The following lists the Pantheon JSON-RPC API commands:

## Admin Methods

!!! note
    The `ADMIN` API is not enabled by default. Use the [`--rpc-api` option](Pantheon-CLI-Syntax.md#rpc-api) to enable the `ADMIN` API.

### admin_peers

Returns networking information about connected remote nodes. 

**Parameters**

None

**Returns**

`result` : *array* of *objects* - Object returned for each remote node. 

Properties of the remote node object are:

* `version` - P2P protocol version
* `name` - Client name
* `caps` - List of Ethereum sub-protocol capabilities 
* `network` - Addresses of local node and remote node
* `port` - Port on the remote node on which P2P peer discovery is listening
* `id` - Node public key. Excluding the `0x` prefix, the node public key is the ID in the enode URL `enode://<id ex 0x>@<host>:<port>`.

## Eth Methods

### eth_syncing

Returns an object with data about the synchronization status, or `false` if not synchronizing.

**Parameters**

None

**Returns**

`result` : *Object|Boolean* - Object with synchronization status data or `false`, when not synchronizing:

* `startingBlock` : *quantity* - Index of the highest block on the blockchain when the network synchronization starts.

    If you start with an empty blockchain, the starting block is the beginning of the blockchain (`startingBlock` = 0).

    If you import a block file using `pantheon import <block-file>`, the synchronization starts at the head of the blockchain, and the starting block is the next block synchronized. For example, if you imported 1000 blocks, the import would include blocks 0 to 999, so in that case `startingBlock` = 1000.

* `currentBlock` : *quantity* - Index of the latest block (also known as the best block) for the current node. This is the same index that [eth_blockNumber](#eth_blocknumber) returns.

* `highestBlock`: *quantity* - Index of the highest known block in the peer network (that is, the highest block so far discovered among peer nodes). This is the same value as `currentBlock` if the current node has no peers.

!!! example
    ```bash tab="curl HTTP request"
    $ curl -X POST --data '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":51}' <JSON-RPC-http-endpoint:port>
    ```
    
    ```bash tab="wscat WS request"
    {"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":51}

### eth_sendRawTransaction

Sends a [signed transaction](../Using-Pantheon/Transactions.md). A transaction can send ether, deploy a contract, or interact with a contract.  

You can interact with contracts using [eth_sendRawTransaction or eth_call](../Using-Pantheon/Transactions.md#eth_call-or-eth_sendrawtransaction).

To avoid exposing your private key, create signed transactions offline and send the signed transaction data using `eth_sendRawTransaction`. 

!!!important
    Pantheon does not implement [eth_sendTransaction](Using-JSON-RPC-API.md#account-management).

**Parameters**

`data` -  Signed transaction serialized to hexadecimal format. For example:

`params: ["0xf869018203e882520894f17f52151ebef6c7334fad080c5704d77216b732881bc16d674ec80000801ba02da1c48b670996dcb1f447ef9ef00b33033c48a4fe938f420bec3e56bfd24071a062e0aa78a81bf0290afbc3a9d8e9a068e6d74caa66c5e0fa8a46deaae96b0833"]`

!!! note
    [Creating and Sending Transactions](../Using-Pantheon/Transactions.md) includes examples of creating signed transactions using the [web3.js](https://github.com/ethereum/web3.js/) library.

**Returns**

`result` : `data` - 32-byte transaction hash

!!! example
    ```bash tab="curl HTTP request"
    $ curl -X POST --data '{"jsonrpc":"2.0","method":"eth_sendRawTransaction","params":["0xf869018203e882520894f17f52151ebef6c7334fad080c5704d77216b732881bc16d674ec80000801ba02da1c48b670996dcb1f447ef9ef00b33033c48a4fe938f420bec3e56bfd24071a062e0aa78a81bf0290afbc3a9d8e9a068e6d74caa66c5e0fa8a46deaae96b0833"],"id":1}' <JSON-RPC-http-endpoint:port>

    }
    ```

### eth_call

Invokes a contract function locally and does not change the state of the blockchain. 

You can interact with contracts using [eth_sendRawTransaction or eth_call](../Using-Pantheon/Transactions.md#eth_call-or-eth_sendrawtransaction).

**Parameters**

*OBJECT* - [Transaction call object](JSON-RPC-API-Objects.md#transaction-call-object).

*QUANTITY|TAG* - Integer representing a block number or one of the string tags `latest`, `earliest`, or `pending`, as described in [Block Parameter](Using-JSON-RPC-API.md#block-parameter).

**Returns**

`result` (*DATA*) - Return value of the executed contract.

!!! example
    ```bash tab="curl HTTP request"
    $ curl -X POST --data '{"jsonrpc":"2.0","method":"eth_call","params":[{"to":"0x69498dd54bd25aa0c886cf1f8b8ae0856d55ff13","value":"0x1"}, "latest"],"id":53}' <JSON-RPC-http-endpoint:port>
    ```
    
    ```bash tab="wscat WS request"
    {"jsonrpc":"2.0","method":"eth_call","params":[{"to":"0x69498dd54bd25aa0c886cf1f8b8ae0856d55ff13","value":"0x1"}, "latest"],"id":53}
    ```
    
    ```json tab="JSON result"
    {
        "jsonrpc": "2.0",
        "id": 53,
        "result": "0x"
    }
    ```

### eth_estimateGas

Returns an estimate of how much gas is needed for a transaction to complete. The estimation process does not use
gas and the transaction is not added to the blockchain. The resulting estimate can be greater than the amount of
gas that the transaction actually uses, for various reasons including EVM mechanics and node performance.

The `eth_estimateGas` call does not send a transaction. You must make a subsequent call to
[eth_sendRawTransaction](#eth_sendrawtransaction) to execute the transaction.

**Parameters**

The transaction call object parameters are the same as those for [eth_call](#eth_call), except that in `eth_estimateGas`,
all fields are optional. Setting a gas limit is irrelevant to the estimation process (unlike transactions, in which gas
limits apply).

*OBJECT* - [Transaction call object](JSON-RPC-API-Objects.md#transaction-call-object).

**Returns**

`result` : `quantity` -  Amount of gas used.

The following example returns an estimate of 21000 wei (0x5208) for the transaction.

!!! example
    ```bash tab="curl HTTP request"
    $ curl -X POST --data '{"jsonrpc":"2.0","method":"eth_estimateGas","params":[{"from":"0xFE3B557E8Fb62b89F4916B721be55cEb828dBd73","to":"0x44Aa93095D6749A706051658B970b941c72c1D53","value":"0x1"}],"id":53}' <JSON-RPC-endpoint:port>
    ```
    
    ```bash tab="wscat WS request"
    {"jsonrpc":"2.0","method":"eth_estimateGas","params":[{"from":"0xFE3B557E8Fb62b89F4916B721be55cEb828dBd73","to":"0x44Aa93095D6749A706051658B970b941c72c1D53","value":"0x1"}],"id":53}

      "jsonrpc" : "2.0",
      "id" : 53,
      "result" : "0x5208"
    }
    ```

The following example request estimates the cost of deploying a simple storage smart contract to the network. The data field
contains the hash of the compiled contract to be deployed. (You can obtain the compiled contract hash from your IDE;
for example, **Remix > Compile tab > details > WEB3DEPLOY**.) The result is 113355 wei.

**Returns**

### debug_traceTransaction

[Remix](https://remix.ethereum.org/) uses `debug_traceTransaction` to implement debugging. Use the _Debugger_ tab in Remix rather than calling `debug_traceTransaction` directly.  

Reruns the transaction with the same state as when the transaction was executed. 

**Parameters**

`transactionHash` : `data` - Transaction hash.

`Object` - request options (all optional and default to `false`):
* `disableStorage` : `boolean` - `true` disables storage capture. 
* `disableMemory` : `boolean` - `true` disables memory capture. 
* `disableStack` : `boolean` - `true` disables stack capture. 

**Returns**

`result`:`object` - [Trace object](JSON-RPC-API-Objects.md#trace-object).
