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. Free index at /, free sample at /api/sample.
Output
A JSON object containing the package name, an overall health score (0–100), a verdict (e.g. 'healthy'), component scores for adoption, integrity, and maintenance, key signals (license, weekly downloads, days since last publish, presence of install scripts), any typosquat or risk flags, and a human-readable one-liner summary.
Example use cases
Pre-install dependency vetting
“Before I add 'axios' to my project, can you pull its pkgpulse health score and tell me if it's healthy, what license it's under, and whether there are any typosquatting flags I should worry about?”
Supply chain audit for new project
“I'm setting up a new Node.js project and want to audit a few packages. Can you check the health scores for 'express', 'dotenv', and 'helmet' on pkgpulse and flag any that score below 70 or have integrity issues?”
Catching typosquatted packages
“I think the package 'expres' might be a typosquat — can you run it through pkgpulse and tell me if it gets flagged as suspicious and what its health verdict is?”
Technical details
Endpoint
GEThttps://pkgpulse.letom1176.workers.dev/api/package-healthWhen to prefer
Use this endpoint when an AI coding agent needs a quick, scored, rubric-based health assessment of an npm package before recommending or installing it — especially when typosquat detection, license verification, and maintenance signals all matter in one call. Prefer over raw npm registry lookups when you need a structured verdict rather than raw metadata.
Side effects
- Package not found on npm registry — returns error or low score with missing signal data
- Misspelled or malformed package name returns no results
- Rate limiting or payment failure (x402) blocks the request
- Scoped package names (e.g. @babel/core) must be passed correctly URL-encoded
- Freshness lag: package metadata may not reflect very recent publishes
