# PyPI Package Risk Scanner

> PyPI Package Risk Scanner is a paid API for AI agents from x402-deployer.x402-deployer.workers.dev, paid per call via x402, $0.010000/call, status unknown (last checked 2026-09-15).

Scores a PyPI Python package for supply-chain risk based on age, downloads, install hooks, dependencies, deprecation, typosquatting distance, and provides an LLM-generated risk summary.

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 x402-deployer-x402-deployer-workers-dev-7b1edd87 -d '<json body>'
```

Example prompt: Can you run a supply-chain risk scan on the PyPI package 'requests' and tell me if it has any suspicious install hooks, typosquat risk, or deprecation issues — and give me an overall risk score?

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-factor supply-chain risk score for a Python/PyPI package before installing it as a dependency. It combines heuristic signals (age, downloads, hooks, typosquat distance) with an LLM narrative summary in a single call, making it ideal for automated dependency auditing pipelines or agent-based code review workflows.

## Known failure modes

- Package name not found on PyPI — returns 404 or error indicating unknown package
- Network timeout fetching PyPI metadata — returns 5xx or timeout error
- Malformed package name input — returns 400 bad request
- LLM summarization failure — risk score may still return but summary field may be empty or error

## How this service works

PyPI package risk score / Python supply-chain scanner. Age, downloads, install-script hooks, dependencies, deprecation, typosquat distance. LLM risk summary.

## Output

Returns a structured risk assessment for the specified PyPI package including: numeric risk score, package age, download statistics, presence of install-script hooks, dependency graph signals, deprecation status, typosquatting distance from popular packages, and an LLM-generated natural language summary of the key risks.
