# JSON-RPC API Methods
|
|
|
|
|
|
!!! attention
|
|
|
All JSON-RPC HTTP examples use the default host and port endpoint `http://127.0.0.1:8545`.
|
|
|
|
|
|
If using the [--rpc-http-host](../Reference/Pantheon-CLI-Syntax.md#rpc-http-host) or [--rpc-http-port](../Reference/Pantheon-CLI-Syntax.md#rpc-http-port)
|
|
|
options, update the endpoint.
|
|
|
|
|
|
## Admin Methods
|
|
|
|
|
|
!!! note
|
|
|
The `ADMIN` API methods are not enabled by default. Use the [`--rpc-http-api`](Pantheon-CLI-Syntax.md#rpc-http-api)
|
|
|
or [`--rpc-ws-api`](Pantheon-CLI-Syntax.md#rpc-ws-api) options to enable the `ADMIN` API methods.
|
|
|
|
|
|
### admin_addPeer
|
|
|
|
|
|
Adds a [static node](../Configuring-Pantheon/Networking/Managing-Peers.md#static-nodes).
|
|
|
|
|
|
!!! caution
|
|
|
If connections are timing out, ensure the node ID in the [enode URL](../Configuring-Pantheon/Node-Keys.md#enode-url) is correct.
|
|
|
|
|
|
**Parameters**
|
|
|
|
|
|
`string` : [Enode URL](../Configuring-Pantheon/Node-Keys.md#enode-url) of peer to add
|
|
|
|
|
|
**Returns**
|
|
|
|
|
|
`result` : `boolean` - `true` if peer added or `false` if peer already a [static node](../Configuring-Pantheon/Networking/Managing-Peers.md#static-nodes).

## 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.
|
|
|
|
|
|

### eth_sendRawTransaction
|
|
|
|
|
|
Sends a [signed transaction](../Using-Pantheon/Transactions/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/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](../JSON-RPC-API/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/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

```
|
|
|
|
|
|
### 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/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](../JSON-RPC-API/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}' http://127.0.0.1:8545

|
|
|
|
|
|
```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.
|
|
|
|
|
|

|
|
|
```bash tab="curl HTTP request"

|
|
|
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.

## EEA Methods
|
|
|
|
|
|
!!! note
|
|
|
The `EEA` API methods are not enabled by default. Use the [`--rpc-http-api`](Pantheon-CLI-Syntax.md#rpc-http-api)

|
|
or [`--rpc-ws-api`](Pantheon-CLI-Syntax.md#rpc-ws-api) options to enable the `EEA` API methods.
|
|
|
|
|
|
### eea_sendRawTransaction
|
|
|
|
|
|
Creates a private transaction from a signed transaction, generates the transaction hash and submits it
|
|
|
to the transaction pool, and returns the transaction hash of the Privacy Marker Transaction.
|
|
|
|
|
|
The signed transaction passed as an input parameter includes the `privateFrom`, `privateFor`, and `restriction` fields.
|
|
|
|
|
|
To avoid exposing your private key, create signed transactions offline and send the signed transaction
|
|
|
data using `eea_sendRawTransaction`.
|
|
|
|
|
|
!!! important
|
|
|
For production systems requiring private transactions, we recommend using a network
|
|
|
with a consensus mechanism supporting transaction finality. For example, [IBFT 2.0](../Consensus-Protocols/IBFT.md).
|
|
|
|
|
|
**Parameters**
|
|
|
|
|
|
`data` - Signed RLP-encoded private transaction. For example:
|
|
|
|
|
|
`params: ["0xf869018203e882520894f17f52151ebef6c7334fad080c5704d77216b732881bc16d674ec80000801ba02da1c48b670996dcb1f447ef9ef00b33033c48a4fe938f420bec3e56bfd24071a062e0aa78a81bf0290afbc3a9d8e9a068e6d74caa66c5e0fa8a46deaae96b0833"]`
|
|
|
|
|
|
**Returns**
|
|
|
|
|
|
`result` : `data` - 32-byte transaction hash
|
|
|
|
|
|
!!! tip
|
|
|
If creating a contract, use [eea_getTransactionReceipt](#eea_gettransactionreceipt) to retrieve the contract
|
|
|
address after the transaction is finalized.
|
|
|
|
|
|
!!! example
|
|
|
```bash tab="curl HTTP request"
|
|
|
curl -X POST --data '{"jsonrpc":"2.0","method":"eea_sendRawTransaction","params": ["0xf869018203e882520894f17f52151ebef6c7334fad080c5704d77216b732881bc16d674ec80000801ba02da1c48b670996dcb1f447ef9ef00b33033c48a4fe938f420bec3e56bfd24071a062e0aa78a81bf0290afbc3a9d8e9a068e6d74caa66c5e0fa8a46deaae96b0833"], "id":1}' http://127.0.0.1:8545
