## Check your exact address

Connect Commerce for Agents to ChatGPT or Claude once (free, no API key; the connector URL is `https://mcp.commerceforagents.com/mcp`, see [how to connect](https://commerceforagents.com/connect)), then ask:

```
Which home internet providers serve my address? [your street address, Seattle, WA ZIP]
```

The assistant calls the `compare-broadband` tool and returns the providers, technologies and top speeds for the census block of your address. The address is used only to look up the census block and is not stored.
