## How to call it through Zero

```sh
zero fetch --capability glianaai-face-compare-facd0b42
```

Example prompt: Can you compare these two face photos and tell me if they're the same person? Here's the first image: https://example.com/photo1.jpg and the second: https://example.com/photo2.jpg

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call face comparison with no signup friction, accepting both image URLs and base64 inputs. Ideal for AI agents performing quick identity checks, de-duplication of user photos, or verification workflows using USDC micropayments via x402.

## Known failure modes

- No face detected in one or both images — returns error indicating face not found
- Invalid or unreachable image URL — returns fetch or URL error
- Base64 image too large or malformed — returns payload error
- Images contain multiple faces — ambiguous match result or error
- Low-quality or obscured face image — low confidence score or failure
- Missing required body fields (a or b) — returns validation error

## How this service works

tools/face-compare: utility API on GlianaAI - pay-per-call, no signup, USDC. Input: { a:{image_url|image_base64}, b:{image_url|image_base64} }. Upload each image to /v1/media first for URLs; base64 only for small images. https://ai.glianalabs.com

## Output

Returns a similarity score (likely 0–1 or percentage) indicating how closely the two faces match, along with a boolean or categorical match result and confidence level
