x402
Stormap Package Safety Check is a paid API for AI agents from stormap.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).
Checks whether an npm or PyPI package is safe to install by analyzing its existence, malicious reports, vulnerabilities, deprecation status, age, install scripts, download counts, and typosquat risks — returning a verdict with reasons.

How this service works
Use when an npm or PyPI package is about to be installed, especially a name an LLM suggested. Returns ok_to_install, caution, dont_install or does_not_exist with reasons: malicious-package reports, known vulnerabilities for the version with the fixed version, deprecated or yanked, age, install scripts, downloads and typosquat look-alikes. From OSV.dev, deps.dev, npm and PyPI. ecosystem=pypi for Python. Errors: 400 bad_input, 502 registry unreachable. Failed calls are not charged.
Output
A structured safety verdict (e.g. safe / caution / unsafe) with supporting reasons including: whether the package exists on the registry, any malicious-package reports, known CVEs for the requested version with recommended fix versions, deprecation or yanked status, package age, presence of suspicious install scripts, download volume, and a list of typosquat look-alike package names.
Example use cases
Pre-install security check for a dependency
“Before I add requests==2.31.0 to my Python project, can you check if it's safe — any known vulnerabilities, malicious reports, or signs it's a typosquat?”
Suspicious package name investigation
“I found a package called 'coIors' on npm — is that a real package or could it be a typosquat of the popular 'colors' library? Check if it's safe.”
CI pipeline dependency audit
“We're about to ship and I need to know if express@4.18.2 has any unpatched vulnerabilities or has been flagged as malicious — give me a safety verdict with reasons.”
Technical details
Endpoint
GEThttps://stormap.ai/x402/v1/package_check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent or developer needs a comprehensive, single-call safety assessment of a specific package before installation — combining vulnerability data, malicious-package intelligence, typosquat detection, and registry metadata in one verdict. Prefer over raw npm audit or PyPI APIs when you need an opinionated, human-readable verdict rather than raw data, or when you need cross-signal analysis (e.g. combining CVEs with install script analysis and typosquat checks).
Side effects
- Package name not found on registry — returns not-found verdict
- Invalid version specifier format — may return error or fall back to latest
- Ambiguous ecosystem — defaults to npm if ecosystem not specified for Python-style names
- Rate limiting or payment failure — 402 response requiring x402 payment
- Upstream registry API unavailability — may return partial or cached data
