Imagga

Verified Jul 2026

Imagga offers image-recognition building blocks — auto-tagging, categorization, visual search, smart cropping, and NSFW moderation — through a REST API authenticated with HTTP Basic Auth (an API key/secret pair) and wildcard CORS support. Its free tier has shrunk to 100 requests/month, down from the 1,000/month it once offered, with paid plans starting at $79/month for 70,000 requests.

Auth quickstart

  1. Sign up with the provider to get an API key.
  2. Send it on every request as a headerAuthorization: <key>
  3. The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Stored keyNo key stored

Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
