Docker Hub API
FreemiumLiveLast verified 24 Sept 2026
Looks up public Docker image metadata—tags, digests, architectures—for any Docker Hub repository.
Example request
curl -s 'https://hub.docker.com/v2/repositories/library/nginx/tags?page_size=3'
Free tier, in plain English
Public repository and tag metadata can be read without any credentials; Docker documents a per-minute rate limit but doesn't publish the exact number.
