# Package Security Audit (npm/PyPI)

> Package Security Audit (npm/PyPI) is a paid API for AI agents from api.strale.io, paid per call via x402, $0.054001/call, status unknown (last checked 2026-10-10).

Runs a composite security audit on an npm or PyPI package, combining CVE checks, OpenSSF Scorecard, license analysis, freshness, and supply chain anomaly detection into a 0-100 risk score.

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 api-strale-io-cdeee8d5
```

Example prompt: Can you run a full security audit on the npm package 'lodash' version 4.17.21 — I want to know its CVE exposure, OpenSSF scorecard, license, freshness, and whether there are any supply chain red flags like publisher changes or install scripts?

## When to prefer this

Choose this endpoint when you need a holistic, multi-dimensional security assessment of a single npm or PyPI package — especially when supply chain risk (publisher changes, install scripts, provenance) matters as much as CVE exposure. Prefer this over a plain CVE checker when you want a single normalized risk score that combines vulnerability data, project health (OpenSSF), license risk, and freshness in one call.

## Known failure modes

- Package not found in the specified ecosystem — returns 404 or empty result
- Unsupported ecosystem value (anything other than 'npm' or 'pypi') — returns validation error
- Missing required 'name' query parameter — returns 400 bad request
- Version string not found for the given package — may return audit for latest or an error
- OSV.dev or OpenSSF upstream services unavailable — may return partial results or timeout

## How this service works

Composite security audit for npm and PyPI packages with supply chain anomaly detection

## Output

Returns a 0-100 composite risk score along with detailed sub-findings: known CVEs from OSV.dev, OpenSSF Scorecard rating, license type and any compliance concerns, package freshness/staleness, and supply chain anomaly flags such as publisher change, provenance regression, and presence of install scripts.
