+Web3 has the following methods built in:

+- eth_blockNumber/0
+- eth_getBalance/2
+- eth_getBlockByHash/2
+- eth_getBlockByNumber/2
+- eth_getCode/2
+- net_version/0
+- eth_getTransactionByHash/1
+- eth_getUncleByBlockHashAndIndex/2
+- eth_getTransactionByBlockHashAndIndex/2
+- eth_getTransactionByBlockNumberAndIndex/2
+- eth_getBlockTransactionCountByHash/1
+- eth_getBlockTransactionCountByNumber/1
+- eth_getTransactionReceipt/1
+- eth_gasPrice/0
+- eth_getTransactionCount/2
+- eth_sendRawTransaction/1
+
+You can get details at [Infura.io](https://docs.infura.io/infura/networks/ethereum/json-rpc-methods/eth_gasprice)
+
+By the way, you can define the eth API.
+
+```elixir
+defmodule MyApp.MyApplication do
+  use Web3, rpc_endpoint: "https://bsc-dataseed4.ninicoin.io"
+
+  dispatch :eth_chainId, args: 0
+end
+```
+
+Macro dispatch receives 2 parameters.

+- Infura same method name, e.g.: :eth_chainId
+- Options:
+
+  Field       | Required|  Description          | Default
+  ----------- | --------| --------- | -------------
+  `name`      | `false`  | Alias name | (empty)
+  `args`      | `false`  | Number of parameters received by the method |  0
+  `return_fn` | `false`  | Return value types, you can use anonymous functions | :raw
