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.

Example use cases

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?”

Technical details

Endpoint

GEThttps://api.strale.io/x402/package-security-audit?utm_source=zero.xyz

When to prefer

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.

Side effects

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
