## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability docker-hub-image-info-67b3d8a4
```

Example prompt: Can you pull up the Docker Hub info for the nginx image — I want to see the pull count, star count, when it was last updated, and the 10 most recent tags with their sizes?

## When to prefer this

Choose this endpoint when you need quick, structured metadata about a public Docker Hub image without scraping or authenticating to Docker Hub yourself. Ideal for supply-chain research, dependency audits, CI/CD pre-flight checks, or comparing image freshness and popularity. At $0.01 per call it is cost-effective for single-image lookups or batch audits.

## Known failure modes

- Image not found on Docker Hub (invalid or misspelled image name)
- Docker Hub API rate limiting or downtime causing failed lookups
- Private or restricted images returning no data
- Missing tag metadata for images with non-standard publishing workflows
