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 ecosyste-ms-pypi-package-metadata-lookup-af66ded8 -d '<json body>'
```

Example prompt: Can you pull up the ecosyste.ms metadata for the PyPI package 'requests' — I want to see its repository info, ecosystem stats, and any dependency data available?

## When to prefer this

Use this endpoint when you need rich, aggregated ecosystem metadata (repo stats, dependencies, maintainer signals) for a Python/PyPI package beyond what the raw PyPI API provides. Prefer this over direct PyPI API calls when ecosyste.ms enrichment (stars, forks, ecosystem health signals) is needed.

## Known failure modes

- Package name not found on PyPI — returns empty or error JSON
- Misspelled package name yields no results
- ecosyste.ms data not yet indexed for a very new or obscure package
- Rate limiting or payment failure for the $0.02 USDC x402 charge

## How this service works

Aggregated ecosyste.ms metadata for PyPI package {q}. Query: ?q= Returns JSON.

## Output

A JSON object containing aggregated ecosyste.ms metadata for the queried PyPI package, typically including repository URL, stars, forks, dependency counts, version details, maintainer info, and other ecosystem signals.
