# Docker Hub vertical extractor

**Action:** `docker_hub`

**Matches:** `hub.docker.com/r/:namespace/:repo`, `hub.docker.com/_/:repo` (official images)

### Examples

```
# Official image (the `_` prefix maps to "library" namespace)
web_extract action=docker_hub url="https://hub.docker.com/_/nginx"

# Community image
web_extract action=docker_hub url="https://hub.docker.com/r/jupyter/datascience-notebook"

# Official Node image
web_extract action=docker_hub url="https://hub.docker.com/_/node"

# Organization image
web_extract action=docker_hub url="https://hub.docker.com/r/bitnami/postgresql"
```

**Returns:** namespace, name, type, description, stars, pulls, private, owner, createdAt, updatedAt

## Instead of

If you're tempted to reach for:
- `curl -s https://hub.docker.com/v2/repositories/:namespace/:repo | jq ...`
- `curl -s https://hub.docker.com/v2/repositories/library/:repo | jq ...` (official images)
- Scraping Docker Hub HTML

**Stop.** This vertical calls the Docker Hub API internally and returns structured namespace/name/stars/pulls/description in one call. No `curl | jq` needed.

## Browser fallback

Default to this vertical's API path; it is faster and more reliable than browser rendering. Use `mode=browser` only as an explicit fallback when the normal API path is blocked/rate-limited or when you need a logged-in CloakBrowser session (`sessionId` + `saveSession=true`).
