# VisionFaceVerify `vision.face-verify@1`

Generated at 2026-11-13 06:25:48 UTC from [`openvibe-contracts v0.419.0`](https://github.com/OpenVibers/OpenVibe.Contracts/tree/v0.419.0) and [`openvibe-sdk v0.161.0`](https://github.com/OpenVibers/OpenVibe.SDK/tree/v0.161.0).

- Version: 1.0.0
- Owner: vision
- Visibility: first-party
- Status: active
- Compatibility: backward
- Schema: [`https://openvibe.network/contracts/vision/face-verify.v1.json`](/docs/contracts/vision.face-verify.json)

vision.face-verify@1: POST /api/v1/faces/verify compares this person's own verification attempt with their enrolled template. It always requires that person's verify consent; without it the answer is faces.consent\_required whether or not a template exists. A match alone never unlocks anything: liveness and a second factor are separate.

## Fields

| Field | Type | Required | Description | Constraints |
| --- | --- | --- | --- | --- |
| `score` | number | yes |  | - `minimum 0`<br>- `maximum 1` |
| `match` | boolean | yes |  |  |
| `threshold` | number | yes |  | - `minimum 0`<br>- `maximum 1` |
| `liveness` | enum | yes |  | - `one of "not_checked", "checked"` |
