How this service works
npm package trust check / risk score / security audit: registry age, weekly downloads, GitHub org/stars, OSV.dev vulnerabilities, typosquat detection.
Output
Returns a trust score (numeric), a verdict string (e.g. trusted, risky, unknown), and the package name. Underlying data draws from npm registry age, weekly download counts, GitHub organization and star count, and known OSV.dev vulnerability records.
Example use cases
Vetting a new npm dependency
“Before I add 'axios' to my project, can you pull its trust and risk score — I want to see its download numbers, how old it is, any known vulnerabilities, and whether it's backed by a legit GitHub org?”
Auditing a suspicious package
“I found a package called 'colors2023' in our package.json that I don't recognize — can you run a trust check on it and tell me if it looks risky or legitimate?”
Comparing packages before adoption
“We're deciding between 'node-fetch' and 'got' for HTTP requests — can you get the trust scores for both so we can compare their security posture and community health?”
Technical details
Endpoint
GEThttps://x402-api-catalog.onrender.com/api/trust-checkWhen to prefer
Choose this endpoint when you need a quick, composite trust signal for an npm package before adding it as a dependency, auditing an existing dependency, or evaluating open-source supply chain risk. It aggregates multiple signals (registry longevity, community adoption, GitHub credibility, known CVEs) into a single score, saving you from querying npm, GitHub, and OSV.dev separately.
Side effects
- Package not found on npm registry — returns an error or low-confidence score
- No GitHub repo link in npm metadata and no repo override provided — GitHub signals may be missing
- OSV.dev API unavailable — vulnerability data may be incomplete
- Invalid or misspelled package name — returns error
- Rate limiting or upstream timeouts from GitHub or OSV.dev
