How this service works
Dependency intelligence for AI coding agents, paid per-call via x402 (USDC on Base): npm package health scores with a disclosed rubric, typosquat checks, dependency audits, OSV known-vulnerability scans (npm, PyPI, Go, crates.io, Maven and more) and PyPI preflight checks. Free index at /, free sample at /api/sample.
Output
A JSON object with a summary (total packages scanned, counts of malicious/not-found/vulnerable, advisories broken down by severity: low/medium/high/critical), a human-readable verdict string (e.g. 'fix now: critical or high severity vulnerabilities present'), the detected input format, and a worst_offenders array listing each vulnerable package with its recommended upgrade version, vulnerability count, and maximum severity.
Example use cases
Pre-deploy security gate for Node app
“Before I deploy, scan these npm packages for known vulnerabilities: express@4.18.1, axios@0.21.1, jsonwebtoken@8.5.1 — flag anything critical or high and tell me what to upgrade to.”
Python data pipeline dependency audit
“Check these PyPI packages for security issues: pypi:numpy@1.23.0, pypi:pandas@1.4.2, pypi:requests@2.27.0 — I need to know the worst offenders and severity levels before I push to production.”
Multi-ecosystem monorepo vulnerability check
“Audit my mixed dependencies for OSV vulnerabilities: lodash@4.17.20, go:golang.org/x/net@0.0.0-20220425223048-2871e0cb64e4, crates:serde@1.0.130 — give me a severity breakdown and tell me if anything is critical.”
Technical details
Endpoint
GEThttps://pkgpulse.letom1176.workers.dev/api/vuln-audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, per-call vulnerability scan across one or more packages from multiple ecosystems in a single query, especially when you want OSV-backed severity rankings and concrete upgrade advice. Prefer it over the POST batch audit endpoint when you have a short list of specific packages rather than a full package-lock.json or requirements file. It is the right choice for pre-deploy checks, CI pipeline spot-checks, or when an agent needs to verify a handful of dependencies on demand without uploading a full manifest.
Side effects
- Missing or malformed 'packages' query parameter returns a 400 error
- Unknown package names return a not_found count in summary but do not fail the request
- Payment not included or insufficient USDC returns HTTP 402 requiring x402 payment
- Ecosystem prefix typo (e.g. 'pip:' instead of 'pypi:') may cause package not found
- Rate limiting or upstream OSV database unavailability may cause 5xx errors
