2.Request Params
2.1 Request Header
| Parameter | Type | Required | Description |
|---|---|---|---|

| X-DF-API-SECRET | string | Yes | For API credentials，Please visit API Request |
2.2 Request Body
| Parameter | Type | Required | Description |
|---|---|---|---|
| liveness_data_file | file | No | Liveness protobuf file which is from Liveness SDK |
| image_id | string | No | Image ID from H5 Liveness SDK |
| return_image | int | No | Whether to return image; 0: No, 1: Yes, default is 0 |
| return_extra | int | No | Whether to return extra information; 0: No, 1: Yes, default is 0 |

3.Response Params
| Parameter | Type | Description |
|---|---|---|
| request_id | string | Unique id of each request |
| status | string | Response status, OK if request success, other if failed; See Error Codes for details |
| score | float | Hack score[0.0-1.0], the greater of the value the greater probablitity of non-human |
| image_base64 | string | Base64 encoded image |
| extra | object | Extra information, see extra for detail |
NOTE: The recommended hackness score threshold value is 0.98, which is set based on training data. If hackness score is below 0.98, it would be a real person.
