# Docker Hub Image Health Check

> Docker Hub Image Health Check is a paid API for AI agents from package-registries.x402tookit.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-30).

Returns health metadata for a Docker Hub image including official status, pull/star counts, last push age, recent tags, and supported architectures.

## Facts

- Endpoint: GET https://package-registries.x402tookit.com/docker-image-health?utm_source=zero.xyz
- Price: $0.03/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-30
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/docker-hub-image-health-check-6916e34f
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_UQ9g46yHCRS9jBDplu74w

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-hub-image-health-check-6916e34f
```

Example prompt: Can you check the health of the nginx Docker image — is it official, how many pulls does it have, when was it last updated, and what architectures does it support?

## When to prefer this

Use this endpoint when you need a comprehensive health snapshot of a Docker Hub image in a single call — including official status, popularity metrics, recency, multi-architecture support, and a pre-computed health verdict. Prefer this over manually scraping Docker Hub when you want structured, agent-consumable data with an opinionated health assessment rather than raw registry metadata.

## Known failure modes

- Image not found on Docker Hub — returns null or error status
- Invalid image name format causes 400-level error
- Docker Hub rate limiting causes temporary failures
- Very new or private images may return incomplete data
- Network timeout if Docker Hub API is slow

## How this service works

Health of a Docker Hub image: official or not, pulls, stars, last push age, recent tags and supported architectures.

## Output

Returns a structured object with: image name, official flag, pull count, star count, days since last update, last updated timestamp, created timestamp, list of recent tags (with name, size, and last updated), supported platforms/architectures, a health verdict and summary, reasons for any degraded status, a source URL to the Docker Hub page, and a disclaimer.
