## How to Connect via cURL

Here's how you add your access credentials to a cURL request:

```curl
curl --location --request POST 'YOUR_ENDPOINT_URL' \ --header 'X-Auth-Token: YOUR_AUTH_TOKEN' \ --header 'Content-Type: application/json' \ --data-raw '{ "jsonrpc": "2.0", "method": "RPC_METHOD", "params": METHOD_PARAMS }' 
```

* Replace `YOUR_ENDPOINT_URL` with the Endpoint URL in the [Blockdaemon app](https://app.blockdaemon.com/signin/register).
* Replace `YOUR_AUTH_TOKEN` with the Auth Token in the [Blockdaemon app](https://app.blockdaemon.com/signin/register).
* Replace `RPC_METHOD` with your chosen [RPC method](https://docs.blockdaemon.com/reference/supported-optimism-methods).
* Replace `METHOD_PARAMS` with the params for your method.
