# docker-image-tags

> docker-image-tags is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns up to 50 newest Docker Hub image tags with last-updated dates, compressed sizes, and supported architectures, with optional substring filtering.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-image-tags-d1e8db5f
```

Example prompt: Can you pull the latest tags for the library/node Docker Hub image, filtered to only show alpine variants, and tell me which ones were updated most recently along with their compressed sizes and supported architectures?

## When to prefer this

Use this endpoint when you need a quick, structured lookup of recent Docker Hub image tags including sizes and architectures without authenticating directly with Docker Hub. Ideal for agents that need to pick base images, check for updates, or verify multi-arch support. Prefer this over manual Docker Hub browsing or the Docker Hub API when cost per call ($0.01) is acceptable and you want a clean, filtered result set ready for decision-making.

## Known failure modes

- Image not found on Docker Hub — returns error or empty result
- Invalid image name format — request rejected
- No tags matching the filter substring — empty tags list returned
- Docker Hub API unavailable — upstream timeout or error
- Rate limiting or payment failure — 402 or quota error

## How this service works

Recent tags of a Docker Hub image: up to 50 newest tags with last-updated date, compressed size and architectures, optional substring filter after a pipe (e.g. 'library/node | alpine'), plus counts. Pick base images and track updates. $0.01 per image.

## Output

A list of up to 50 most recent tags for the specified Docker Hub image, each including the tag name, last-updated timestamp, compressed size, and supported architectures, along with total tag counts. Supports optional substring filtering (e.g. 'alpine') to narrow results.
