How this service works
Check npm package metadata, maintenance signals, deprecation, license, dependencies, and OSV vulnerabilities.
Output
Returns structured metadata for the specified npm package including: package name and version details, deprecation status, maintenance signals (release recency, activity), license type, dependency list, and any OSV (Open Source Vulnerabilities) advisories matching the package.
Example use cases
Security audit before npm install
“Can you check the npm package 'colors' version 1.4.0 for any known vulnerabilities, deprecation warnings, and license issues before I install it?”
Open source license compliance check
“I need to verify that 'axios' on npm has a permissive license compatible with commercial use and isn't flagged for any supply chain issues — can you run a preflight on it?”
Unmaintained dependency review
“We're auditing our dependencies — can you check if 'request' on npm is still maintained, whether it's deprecated, and pull up any OSV advisories associated with it?”
Technical details
Endpoint
GEThttps://nohands-coinbase-bazaar.bytoken2023.workers.dev/v1/x402/software/npm-package-preflight?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to vet an npm package before installing or integrating it — especially for supply chain security, license compliance, or dependency health checks. Prefer it over general web search when you need structured, machine-readable vulnerability and maintenance data sourced directly from the npm registry and OSV database.
Side effects
- Package not found on npm registry — returns 404 or error indicating unknown package
- Invalid package name format — returns validation error
- Network or registry timeout when fetching npm or OSV data
- Rate limit or payment failure — x402 payment required at $0.015 USDC per call
- Version not found for specified package version
