# `ETH` methods

The `ETH` API methods allow you to interact with the blockchain.

:::note

Methods with an equivalent [GraphQL](../../../how-to/use-besu-api/graphql.md) 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].

:::

The `ETH` methods are grouped into the following pages.
