## APIs

{% hint style="warning" %}
The differences between Monad and the standard Geth client are described here: <https://docs.monad.xyz/reference/rpc-differences>
{% endhint %}

### JSON-RPC

Monad supports most of the JSON-RPC methods available in Geth. You can find the official documentation [here](https://docs.monad.xyz/reference/json-rpc/)

The linked documentation also includes cURL examples where you just need to replace the RPC URL, e.g:

```bash
curl --request POST \
     --url <TRITON_URL> \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data '
{
  "id": 0,
  "jsonrpc": "2.0",
  "method": "eth_blockNumber",
  "params": []
}
'
```

Expected result:

```bash
{
    "jsonrpc": "2.0",
    "result": "0x23feb61",
    "id": 0
}
```

### Websocket

The websocket API is also available in Monad. You can find the official documentation [here](https://docs.monad.xyz/reference/websockets)

See an example below how to test websocket using the `wscat` utility:

**Install node-ws in Linux**:

```bash
sudo apt update
sudo apt install node-ws
```

**Subscribe to websockets**:

```bash
wscat -c wss://<TRITON_URL>
Connected (press CTRL+C to quit)
> { "id": 1, "jsonrpc": "2.0", "method": "eth_subscribe", "params": ["newHeads"] }
```

Expected result:

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.triton.one/chains/monad.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
