    Checks one package version (npm, PyPI, Go, crates.io, Packagist, RubyGems, Maven, NuGet) against OSV.dev. Free preview tier: verdict and advisory count. The paid x402 endpoint /v1/package adds advisory ids, severity, CVSS and fixed-in versions.

    Description, as the server wrote it
    Checks a package.json, lockfile, requirements.txt, go.mod, Cargo.lock, poetry.lock or composer.lock (or a list of packages) against OSV.dev for known vulnerabilities and confirmed-malicious packages. Free preview tier: verdict and counts, up to 25 packages. The paid x402 endpoint /v1/scan adds per-package advisory ids, severity, CVSS and fixed-in versions (up to 500 packages).

    • idempotentHint: true

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
