## 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-search-b3f3464b -d '<json body>'
```

Example prompt: Search my Verifik face collection (collection ID 'kyc-latam-001') for any matches to these 2 face images with a minimum similarity score of 0.85 using 'accurate' search mode, returning up to 5 results.

## When to prefer this

Use this endpoint when you need to search a pre-built face collection to identify or verify individuals by biometric match, especially in LATAM identity verification workflows. Prefer this over simple 1:1 face comparison endpoints when you have a collection of enrolled faces and need to find the best match(es) for an unknown face. Ideal for KYC/KYB agent pipelines that require pay-per-use biometric search without subscription lock-in.

## Known failure modes

- No faces detected in provided images — returns error indicating unrecognizable or low-quality image
- Collection ID not found or inaccessible — returns 404 or unauthorized error
- min_score out of valid range — returns validation error
- Images array empty or malformed — returns schema validation error
- Payment not fulfilled via x402 — returns 402 Payment Required
- Search mode value not recognized — returns invalid parameter error

## 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

A JSON object containing matched face records from the searched collection, each with a similarity score, match metadata, and a cryptographic signature for result authenticity verification.
