## 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 pypi-package-info-cada2602
```

Example prompt: Can you look up the PyPI package info for 'httpx' — I want to know the latest version, its license, required Python version, dependencies, and how many downloads it gets per month?

## When to prefer this

Use this endpoint when you need structured, up-to-date metadata about a specific Python package from PyPI — especially for dependency auditing, license checks, or popularity assessment. Prefer this over scraping PyPI's web UI or using pip show locally when you need programmatic access in an agent workflow.

## Known failure modes

- Package name not found on PyPI — returns an error or empty result
- Typo in package name leads to wrong package data
- PyPI API is temporarily unavailable causing a timeout
- Package exists but has no published releases, returning incomplete metadata
- Download stats may be delayed or approximate for very new packages

## How this service works

A Python package on PyPI: latest version, summary, license, required Python, dependencies, release date, project links and daily/weekly/monthly downloads. Use to choose or audit a Python dependency.

## Output

Returns a structured object containing the package's latest version string, a short summary, license type, minimum required Python version, list of dependencies, release date of the latest version, project URLs (homepage, documentation, source), and download counts for the past day, week, and month.
