TinEye API
Signing up for the TinEye API has two parts:
1 Creating an account which allows you to validate your email address and get a login.
2 Purchasing a search bundle in order to start searching against the TinEye index.
Once you create an account and validate your email address, you will receive a unique API key which provides access to the API. We have a TinEye API sandbox you can access for testing your integration at no cost.
Complete documentation for the TinEye API is available.
