asynccompare

Overview

  • API URL: /api/v1/zoloz/facecompare/asynccompare
  • API Description: The ZOLOZ Face Compare asynccompare API initializes an asynchronous face comparison request. When you need to frequently call the compare API, it is recommended to use the asynccompare API to avoid response timeouts due to network fluctuations. After the API call completes, you can asynchronously obtain the face comparison results using the asynccheckresult API.

The face images are encoded in Base64 and support JPG, JPEG, PNG, and BMP formats.

Note: For the specific valid docType, please refer to Document types supported and OCR results returned.

Specify whether face2.content is a selfie image or a face image from a document.

  • SELFIE: a selfie image
  • valid docType: a face image from a document which matches docType
  • 00000001007: a face image from a document not supported by ZOLOZ now

Note: If the type of face2.content does not match the value of this field, the matching result will be inaccurate.

"SELFIE"

Note：Currently, the total size of the two images, face1.content and face2.content, must not surpass 5MB. Should it exceed this limit, please compress the images prior to uploading them in order to prevent system errors.
