## 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-tags-lookup-94fdfc0d
```

Example prompt: What tags are available for the official nginx image on Docker Hub? Show me all the versions I can pull.

## When to prefer this

Choose this endpoint when you need a lightweight, no-signup, pay-per-call way to query Docker Hub image tags without managing API keys. Ideal for AI agents operating autonomously that need to discover available Docker image versions programmatically in a DevOps or infrastructure workflow context.

## Known failure modes

- Invalid or non-existent Docker Hub repository name returns an error
- Missing or malformed schema parameter may yield empty or error response
- Payment failure via x402 protocol blocks access entirely
- Rate limits or Docker Hub API availability issues may cause timeouts
- Private or restricted repositories may not return tag data
