## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability basebuilder-linkedin-face-detection-f74b5623 -d '<json body>'
```

Example prompt: Can you run face detection on this image and tell me how many faces are present and where they are located: https://example.com/profile-photo.jpg?

## When to prefer this

Use this endpoint when you need to detect and locate faces within images in the context of LinkedIn profile workflows or when using the BaseBuilder LinkedIn API hub ecosystem. Prefer this over general-purpose vision APIs when already integrated with other BaseBuilder LinkedIn endpoints.
