Developing with Kairos

API Changelog

 
12/15/18
  • We’ve been working hard on an upgrade to make Kairos’ API faster and more stable for you —dramatically improving overall performance. This upgrade fixes issues with slow response times and increased error rates when making API calls.
10/15/18
  • We shipped a huge update to Kairos’ algorithms; we’re now 100% Deep Learning, improving accuracy and performance for all customers of the API.
  • We launched an On-Premises version of our popular Face Recognition Cloud API; customers can now self-host a version of Kairos in their own datacenter.

  • We have a big enhancement being released today. We have rewritten our entire facial recognition backend in Go!
  • What does this mean for you? Not much other than expect to see much more consistent results, and vastly improved response times across all API calls!
  • We also added two new parameters, "show_uploaded_image" which when set to "true" will include a 1 hour temporary URL where you can retrieve the image that was just sent in for the /enroll call.
  • The other parameter that was added is called "show_candidate_images" which when set to "true" will send you a temporary URL for each candidate that appears in a /recognize call. This was a hotly requested feature that we are glad to be able to deliver for you.
  • Note: We did correct an issue with the /enroll call where the "face_id" parameter was returning an integer and not the correct face_id corresponding to what appears in the /recognize call. This has been corrected and a string is now returned.
6/27/17
  • Based on your feedback, we have added the uploaded_image_url to the /verify, /enroll, and /recognize methods!
  • Note that this URL is only good for one hour after it has been created.
  • Look for more new features in this area coming very soon!
6/16/17

  • You can now pass in a face_id to the Remove subject method to remove just one face from a subject
  • The face_id is now passed back to you when you issues an Enroll request
