# Docker Hub tags

**Observed 2026-09-26** at `https://hub.docker.com/v2/repositories/library/nginx/tags?page_size=3`.

- **No auth**; HTTP 200; `count` = 1339 tags; each result carries `name` and `last_updated` (e.g. `mainline-alpine3.24`, `2026-09-26T16:51:49Z`).
- Rate-limit headers present: `x-ratelimit-limit: 180`, `x-ratelimit-remaining`, `x-ratelimit-ip` (per source IP).

An agent can list public image tags and their freshness without auth, within ~180 requests/IP.
