# Client ## CLI A user can query and interact with the `feemarket` module using the CLI. ### Queries The `query` commands allow users to query `feemarket` state. ```go ethermintd query feemarket --help ``` #### Base Fee The `base-fee` command allows users to query the block base fee by height. ``` ethermintd query feemarket base-fee [flags] ``` Example: ``` ethermintd query feemarket base-fee ... ``` Example Output: ``` base_fee: "512908936" ``` #### Block Gas The `block-gas` command allows users to query the block gas by height. ``` ethermintd query feemarket block-gas [flags] ``` Example: ``` ethermintd query feemarket block-gas ... ``` Example Output: ``` gas: "21000" ``` #### Params The `params` command allows users to query the module params. ``` ethermintd query params subspace [subspace] [key] [flags] ``` Example: ``` ethermintd query params subspace feemarket ElasticityMultiplier ... ``` Example Output: ``` key: ElasticityMultiplier subspace: feemarket value: "2" ``` ## gRPC ### Queries | Verb | Method | Description | | ------ | ---------------------------------------------------- | -------------------------------------------------------------------------- | | `gRPC` | `ethermint.feemarket.v1.Query/Params` | Get the module params | | `gRPC` | `ethermint.feemarket.v1.Query/BaseFee` | Get the block base fee | | `gRPC` | `ethermint.feemarket.v1.Query/BlockGas` | Get the block gas used | | `GET` | `/feemarket/evm/v1/params` | Get the module params | | `GET` | `/feemarket/evm/v1/base_fee` | Get the block base fee | | `GET` | `/feemarket/evm/v1/block_gas` | Get the block gas used |
