## 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 cra-agent-pypi-package-metadata-7cbce52f
```

Example prompt: What's the latest version of the requests package on PyPI, what Python version does it require, what licence does it use, and are there any security advisories against the current release?

## When to prefer this

Use this endpoint when you need a single call to get current PyPI package metadata including security advisories, Python compatibility, and licence info — particularly useful in agentic pipelines that need to vet dependencies before installation or audit open source usage for compliance.

## Known failure modes

- Package name not found on PyPI — returns 404 or empty result
- Misspelled package name yields no match
- PyPI API unavailability causes timeout or 503
- Packages with no advisory data may return empty advisories array

## How this service works

## Output

Returns structured data including the latest version string, minimum Python version requirement, licence identifier, list of package dependencies, and any security advisories (CVEs or similar) flagged against the current release of the specified PyPI project.
