Technical details
Endpoint
POSThttps://x402.forgemesh.io/npm-package-healthWhen to prefer
Use this endpoint when an AI coding agent needs to quickly assess npm package health before recommending or installing a dependency — especially useful for checking deprecation status, license compatibility, dependency bloat, or maintainer activity without scraping the npm website directly.
Side effects
- Package name not found on npm registry — returns 404 or error indicating unknown package
- Misspelled or scoped package name causes lookup failure
- npm registry temporarily unavailable — cached data may be stale or endpoint returns 503
- Payment of 0.003 USDC not completed via x402 protocol — request rejected
