Search for similar images

Question

Google

Faced with the task of searching for similar images on the Internet in order to check how unique the original image is.
The best results are obtained by searching through images in Google, but when working through their API there are quite strict limits of 100 requests per day (then for a fee, which is not yet satisfactory) . I also found TinEye.com, which also provides api, but also for a fee and their performance is somewhat worse.
Prompt who faced similar:
— what else there are alternatives;
- are there any ready-made developments in terms of implementation in php;

Answer 1

> - are there any ready-made developments in terms of implementation in php;
What does "earnings" mean? A robot that indexes all the pictures on the Internet? Believe me, API access will cost less than traffic from this robot.

Answer 2

no one is going to write their own "robot". By developments, we mean implementations in the form of a class, a function that uses existing services, etc. And please write to the point, otherwise I’m looking here on Habré just to flood, but to show what all the identified people can do
