#### `admin_generateLogBloomCache`[](https://docs.bit-rock.io/developer/broken-reference)
Generates cached log bloom indexes for blocks. APIs such as `eth_getLogs` and `eth_getFilterLogs` use the cache for improved performance.
Note
Each index file contains 100000 blocks. The last fragment of blocks less than 100000 are not indexed.
**Parameters**[****](https://docs.bit-rock.io/developer/broken-reference)
* `startBlock`: *string* - block to start generating indexes
* `endBlock`: *string* - block to stop generating indexes
**Returns**[****](https://docs.bit-rock.io/developer/broken-reference)

* `toBlock`: *string* - integer representing a block number or one of the string tags `latest`, `earliest`, or `pending`, as described in block parameter
You can skip a parameter by using an empty string, `""`. If you specify:
* No parameters, the call removes cache files for all blocks.
* Only `fromBlock`, the call removes cache files for the specified block.
* Only `toBlock`, the call removes cache files from the genesis block to the specified block.
**Returns**[****](https://docs.bit-rock.io/developer/broken-reference)
`result`: *object* - `Cache Removed` status or `error`.

```
### `DEBUG` methods[](https://docs.bit-rock.io/developer/broken-reference)
The `DEBUG` API methods allow you to inspect and debug the network. The `DEBUG` API is a more verbose alternative to the `TRACE` API, and its main purpose is compatibility with tools such as Remix. Where these APIs overlap, we recommend using the `TRACE` API for production use over the `DEBUG` API. Specifically, we recommend `trace_block` over `debug_traceBlock`, and `trace_transaction` over `debug_traceTransaction`.
Note
The `DEBUG` API methods are not enabled by default for JSON-RPC. To enable the `DEBUG` API methods, use the `--rpc-http-api` or `--rpc-ws-api` options.

### `ETH` methods[](https://docs.bit-rock.io/developer/broken-reference)
The `ETH` API methods allow you to interact with the blockchain.
Note
Methods with an equivalent GraphQL query include a GraphQL request and result in the method example. The parameter and result descriptions apply to the JSON-RPC requests. The GraphQL specification is defined in the schema.
#### `eth_accounts`[](https://docs.bit-rock.io/developer/broken-reference)
Returns a list of account addresses a client owns.

```
#### `eth_call`[](https://docs.bit-rock.io/developer/broken-reference)
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`.
If revert reason is enabled with `--revert-reason-enabled`, the `eth_call` error response includes the revert reason.
**Parameters**[****](https://docs.bit-rock.io/developer/broken-reference)
`call`: *object* - transaction call object
`blockNumber` or `blockHash`: *string* - integer representing a block number, block hash, or one of the string tags `latest`, `earliest`, or `pending`, as described in block parameter
Note
By default, `eth_call` does not fail if the sender account has an insufficient balance. This is done by setting the balance of the account to a large amount of ether. To enforce balance rules, set the `strict` parameter in the transaction call object to `true`.
**Returns**[****](https://docs.bit-rock.io/developer/broken-reference)
`result`: *string* - return value of the executed contract

**Parameters**[****](https://docs.bit-rock.io/developer/broken-reference)
`transaction`: *object* - transaction call object
`blockNumber` or `blockHash`: *string* - integer representing a block number, block hash, or one of the string tags `latest`, `earliest`, or `pending`, as described in block parameter.
**Returns**[****](https://docs.bit-rock.io/developer/broken-reference)

```
#### `eth_estimateGas`[](https://docs.bit-rock.io/developer/broken-reference)
Returns an estimate of the gas required 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 the transaction ends up using, for reasons including EVM mechanics and node performance.
The `eth_estimateGas` call does not send a transaction. You must call `eth_sendRawTransaction` to execute the transaction.
If revert reason is enabled with `--revert-reason-enabled`, the `eth_estimateGas` error response includes the revert reason.
**Parameters**[****](https://docs.bit-rock.io/developer/broken-reference)
For `eth_estimateGas`, all fields are optional because setting a gas limit is irrelevant to the estimation process (unlike transactions, in which gas limits apply).
`call`: *object* - transaction call object
**Returns**[****](https://docs.bit-rock.io/developer/broken-reference)
`result`: *string* - amount of gas used
The following example returns an estimate of 21000 wei (`0x5208`) for the transaction.

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 you want to deploy.

caution
Using `eth_getLogs` to get logs from a large range of blocks, especially an entire chain from its genesis block, might cause Besu to hang for an indeterminable amount of time while generating the response.

note
The `TXPOOL` API methods are not enabled by default for JSON-RPC. To enable the `TXPOOL` API methods, use the `--rpc-http-api` or `--rpc-ws-api` options.
#### `txpool_besuPendingTransactions`[](https://docs.bit-rock.io/developer/broken-reference)
Lists pending transactions that match the supplied filter conditions.
**Parameters**[****](https://docs.bit-rock.io/developer/broken-reference)
* `numResults`: *number* - integer representing the maximum number of results to return
* `fields`: *object* - object of fields used to create the filter condition
Each field in the object corresponds to a field name containing an operator, and a value for the operator. A field name can only be specified once, and can only contain one operator. For example, you cannot query transactions with a gas price between 8 and 9 Gwei by using both the `gt` and `lt` operator in the same field name instance.
All filters must be satisfied for a transaction to be returned.
| Field name | Value | Value type | Supported operators |
| ---------- | -------------------------------------------------- | ---------------- | ------------------- |
| `from` | Address of the sender. | *Data*, 20 bytes | `eq` |
| `to` | Address of the receiver, or `"contract_creation"`. | *Data*, 20 bytes | `eq`, `action` |
| `gas` | Gas provided by the sender. | *Quantity* | `eq`, `gt`, `lt` |
| `gasPrice` | Gas price, in wei, provided by the sender. | *Quantity* | `eq`, `gt`, `lt` |
| `value` | Value transferred, in wei. | *Quantity* | `eq`, `gt`, `lt` |
| `nonce` | Number of transactions made by the sender. | *Quantity* | `eq`, `gt`, `lt` |
Supported operators:
* `eq` (equal to)
* `lt` (less than)
* `gt` (greater than)
* `action`
note
The only supported `action` is `"contract_creation"`.
