# Troubleshooting

## Example Request

You can use the following CURL request to verify your connection to any of our RPC services. Just replace the \<URL> portion with [your RPC URL](/introduction/connection-information.md) and API key.

```
curl <URL> -s -X POST -H "Content-Type: application/json" -d '
  {"jsonrpc":"2.0","id":1, "method":"getHealth"}
'
```

Assuming everything is correct and working right, you should see something like the following image.
