## 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 relaystation-celebrity-detection-fe314ca4 -d '<json body>'
```

Example prompt: Can you tell me which celebrities appear in this photo? Here's the image URL: https://example.com/red-carpet-photo.jpg — I need their names and how confident you are about each one.

## When to prefer this

Choose this endpoint when you need to identify specific named celebrities (public figures) in an image with confidence scores, as opposed to generic object or face detection. It is backed by AWS Rekognition's celebrity database, making it well-suited for media, entertainment, journalism, and content moderation workflows where knowing who appears in an image matters — not just that a person is present.

## Known failure modes

- Image URL is inaccessible or returns a non-image response — endpoint cannot fetch the content
- No celebrities detected — returns an empty list rather than an error
- Low-confidence matches may include false positives for look-alike individuals
- Image too small or face too obscured for recognition — returns empty or low-confidence results
- Unsupported image format — may return an error if the format is not JPEG/PNG/GIF/WebP
- Payment failure via x402 — call is rejected if USDC balance is insufficient
