Google Cloud Vision API
First 1,000 units per feature every month free, forever, for OCR and image labels
Google Cloud Vision detects text (printed and handwritten OCR), labels, faces, landmarks, logos, objects and explicit content in images. Each feature applied to an image is one billable unit. The free quota is per-feature and recurs monthly rather than being a one-time trial.
Free tier
First 1,000 units/feature/month free forever; then ~$1.50/1,000 for most features. New accounts also get $300 trial creditRate limits
Default ~1,800 requests/minute per project; image size up to 20 MB / 75M pixelsAuth
