How this service works
Query Open Source Vulnerabilities (OSV) database for known CVEs in an NPM package. Returns vulnerability list with severity, summary, affected version ranges, fix versions, references. Use ?package=react and version=18.2.0. Backed by Google-maintained OSV (industry standard). Accepts payment on Base or Solana — either network works.
Output
Returns a list of known vulnerabilities from the OSV database for the specified npm package and version, including CVE identifiers, severity levels, human-readable summaries, affected version ranges, recommended fix versions, and external references (e.g. GitHub advisories, NVD links).
Example use cases
Example prompt
“Check the OSV database for known CVEs and security vulnerabilities in the npm package react at version 18.2.0 — I need the severity, affected version ranges, and any available fix versions.”
Technical details
Endpoint
GEThttps://api.x402node.dev/npm/vulnWhen to prefer
Use this endpoint when you need fast, structured CVE/vulnerability data for a specific npm package version backed by Google's OSV database — ideal for automated dependency auditing, CI security checks, or agent-driven supply chain risk assessment. Prefer this over npm audit or Snyk API integrations when you need a lightweight, pay-per-call lookup without OAuth or API key setup.
Side effects
- Package not found in OSV database — returns empty vulnerability list (not an error)
- Invalid or malformed package name — may return 400 or empty result
- Version string not recognized — may return results for all versions or empty set
- Network/upstream OSV API timeout — returns 5xx error
- Missing required package parameter — returns 400 bad request
