How this service works
Check a package before install: malware, known vulnerabilities (OSV), exploited CVEs (CISA KEV) and end-of-life, plus LLM prices; signed answers, pay per call in USDC, no account or API key.
Output
Returns per-package results including: vulnerability advisories with CVE aliases, severity labels, fixed versions, KEV flag, malicious flag, and ecosystem; plus a summary with counts of affected packages, KEV hits, malicious packages, and total advisories; plus signed dataset metadata (OSV snapshot ID, KEV catalog version, SHA256, signature) confirming data freshness and provenance.
Example use cases
Pre-install npm package safety check
“I'm about to add express@4.18.2 and lodash@4.17.20 to my project — can you check both npm packages for known vulnerabilities, exploited CVEs, and any malware flags before I install them?”
Lockfile audit for CI pipeline
“Here's my requirements.txt — can you scan all the packages in it for OSV vulnerabilities and tell me which ones are in the CISA Known Exploited Vulnerabilities catalog so I can prioritize patching?”
Verify dependency safety before deployment
“I need to audit my yarn.lock before deploying to production — run it through the vulnerability checker and give me a summary of anything affected, especially anything with HIGH or CRITICAL severity or that's actively being exploited in the wild.”
Technical details
Endpoint
POSThttps://g5joilnmeep4ntz3nwezxt5dmu.srv.us/v1/osv/check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographically signed, pay-per-call vulnerability data with no account setup — ideal for AI agents doing automated dependency audits in CI/CD pipelines, pre-install checks, or supply chain risk assessments. Prefer it over free OSV API wrappers when you need combined OSV + CISA KEV + malware signals in a single call, signed responses for auditability, and when operating without persistent API keys. Best for spot checks of up to 50 packages per call.
Side effects
- Invalid PURL format causes validation error — PURLs must start with 'pkg:'
- Lockfile format mismatch — submitted lockfile content does not match declared format enum
- Package version not found in OSV — returns no advisories but does not error
- Stale dataset flag set to true if OSV or KEV data is older than cadence window
- Payment failure or insufficient USDC balance returns HTTP 402
- Empty packages array or missing required fields returns 400 validation error
- Network timeout for large lockfiles with many packages
