# Audio and video calls

Only a model can start a call and only with users who are online now and have an open dialog with you. To call a subscriber, click on the phone icon <img src="/files/NuUnyWEmi4wIEGdmLqDr" alt="" data-size="line"> in the upper right corner inside the dialog and select "Call". At the moment audio and video calls do not have a separate payment — you can charge for this service with a tip.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```

```

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.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
