 For example, you can use cURL to send the request:
 
 ```shell
-curl -X POST http://localhost:5000/summarize -H "Content-Type: application/json" -d '{"url": "https://resonatehq.io", "email": "[email protected]"}'
+curl -X POST http://127.0.0.1:5000/summarize -H "Content-Type: application/json" -d '{"url": "https://resonatehq.io", "email": "[email protected]"}'
 ```
 
 You should see the worker downloading the content from the URL, summarizing it, and then sending an "email" with the summary and links to confirm or reject the summarization.
