TinyEye offers a series of AI-powered image recognition services: reverse image search, color search, mobile image recognition (for augmented reality applications), etc. I plan to use their color search API to enrich some of my image-based directories.
Cheapest premium plan: $200 per month
The basic package corresponds to $0.01 per search.
TinEye is best for
brand owners who want to track their visual online presence (via reverse image search) content and applications creators who want to enrich the data attached to their visual assets
