# Saylor Innovations — Python Package Report

> Saylor Innovations — Python Package Report is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-03).

Retrieves a Python package's latest version, Python compatibility, dependencies, license, and PyPI security advisories without executing any code.

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 saylor-innovations-python-package-report-b97c9093
```

Example prompt: Can you pull up the PyPI report for the 'cryptography' package — I want to know its latest version, what Python versions it supports, its dependencies, license, and whether there are any known vulnerabilities?

## When to prefer this

Use this endpoint when you need a quick, read-only snapshot of a Python package's metadata and security posture from PyPI without running any code locally. It is ideal for automated dependency audits, license compliance checks, and pre-integration security vetting in CI/CD pipelines or agentic workflows where code execution is not permitted.

## Known failure modes

- Package name not found on PyPI — returns an error or empty report
- Package exists but has no published releases — may return incomplete data
- PyPI API unavailable — upstream timeout or error
- Misspelled package name returns no results
- Package has no vulnerability data — vulnerabilities array returns empty

## How this service works

Inspect a Python package’s latest release, Python compatibility, declared dependencies, license metadata and PyPI-reported advisories. No code execution.

## Output

Returns a JSON object containing the package name, latest version string, required Python version range, list of declared dependencies, license string, a short summary, and an array of PyPI-reported vulnerability objects (each with an ID, link, and aliases), plus metadata about the data source and retrieval timestamp.
