## 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-id-verify-d7b93234 -d '<json body>'
```

Example prompt: Run a full KYC check on this new user — verify their government ID image, confirm the selfie liveness, and match their face to the ID photo before we let them proceed.

## When to prefer this

Choose this endpoint when you need a single-call, all-in-one KYC solution combining government ID verification, liveness detection, and face matching — especially within an existing Relaystation workflow where you can pair it with /v1/esigndoc for verify-then-sign flows or /v1/screening for sanctions checks, all on one unified balance. Ideal for agents that need compliant identity verification without integrating multiple separate KYC vendors.

## Known failure modes

- Low-quality or blurry ID image causing document read failure
- Liveness check failure if the selfie is a photo of a photo
- Face mismatch if the person submitting differs from the ID
- Unsupported ID type or country not recognized
- Expired or tampered documents rejected
- Insufficient lighting in selfie causing liveness failure
- Missing required fields returns 400 validation error
- Payment failure if account balance is insufficient for $0.10 charge

## How this service works

$0.10/verification. Full KYC in one call — government-ID verification, liveness detection, and face-to-ID matching. Pair with /v1/esigndoc for verify-then-sign and /v1/screening for sanctions. One of 155 Relaystation tools on one balance — relaystation.ai

## Output

Returns a structured KYC result including: overall verification status (pass/fail), document authenticity assessment, liveness detection outcome, and a face-to-ID match confidence score. Likely includes extracted identity fields from the government ID (name, DOB, document number) and individual sub-check results.
