## 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 verifik-ai-face-recognition-compare-live-3ae99007 -d '<json body>'
```

Example prompt: Check if this live selfie image (probe) matches any of the three reference photos in my gallery — use 'SEARCH' mode, require a liveness score of at least 0.7, and tell me the similarity scores and whether the person is verified.

## When to prefer this

Choose this endpoint when you need liveness-aware 1:N face comparison, especially for KYC or identity verification workflows in Latin American markets, require pay-per-call pricing with no subscription lock-in, and need a signed/verifiable response for audit purposes.

## Known failure modes

- Liveness score below liveness_min_score threshold — probe rejected as non-live
- No match found in gallery — returns no-match result
- Invalid or unreadable image in probe or gallery — returns image processing error
- Unsupported OS parameter — returns validation error
- Payment not provided or insufficient — returns HTTP 402
- Malformed request body — returns 400 bad request

## How this service works

Verifik AI — x402 KYC &amp; KYB for autonomous agents, with deep LATAM coverage: national IDs, companies, vehicles, sanctions, and regional registries. Pay per validation, no subscription lock-in.

## Output

Returns a JSON object with a match result indicating whether the probe face matches any gallery image, similarity/confidence scores, liveness score for the probe image, and a signed response for integrity verification.
