Perform an HTTP GET request on the documentation index with the `ask` parameter:

```
GET https://learn.islash.io/islash-insights/meta-introduces-whatsapp-business-calling-api.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.

### Option 2 — Browse the documentation index
