## 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 maven-central-artifact-info-by-group-id-118e5347
```

Example prompt: What's the latest version of junit on Maven Central, and can you give me the ready-to-paste Maven dependency snippet for groupId junit?

## When to prefer this

Use this endpoint when you need quick, structured Maven Central artifact metadata — especially a formatted dependency snippet — without having to scrape the Maven Central website or parse raw search API responses. Ideal for agents that help developers manage Java project dependencies or audit open-source licenses.

## Known failure modes

- groupId not found on Maven Central — returns 404 or empty result
- groupId typo leads to incorrect or no artifact match
- Maven Central upstream unavailable — returns timeout or 503
- artifact exists but has no license metadata — license field may be null or missing

## How this service works

Maven Central artifact info - latest release version, recent versions, licenses, description and ready-to-paste dependency snippet

## Output

Returns the latest release version, a list of recent versions, the artifact's license(s), a short description, and a ready-to-paste dependency snippet (e.g. Maven XML or Gradle format) for the specified Maven Central groupId.
