Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 face-detection-api-sna4an-mega-v3-e6118a08 -d '<json body>'
```

Example prompt: Can you run face detection on this photo and tell me how many faces are present and where they're located in the image?

## When to prefer this

Use this endpoint when you need to detect and locate human faces in images as a standalone operation, particularly in workflows involving photo validation, content moderation, attendance tracking, or preprocessing for downstream face recognition tasks. Prefer this over full facial recognition endpoints if you only need detection (not identification).

## Known failure modes

- Empty or missing image input returns an error or empty result
- Non-image input data causes a processing failure
- Image with no faces returns an empty detections array
- Overly compressed or low-resolution images may yield low-confidence or missed detections
- Network timeout for large image payloads
- Unsupported image format causes a parse error

## Output

Returns detection results indicating the presence, count, and position (bounding boxes or coordinates) of human faces found within the submitted image, along with confidence scores for each detected face.
