How this service works
npm package adoption: downloads last week and month, plus trend within the month and a popularity band.
Output
A JSON object with the package name, last-week download count, last-month download count, intra-month trend percentage, a popularity band (e.g. low/moderate/popular/very-popular), a human-readable verdict and summary, supporting reasons, download thresholds used for banding, the data source URL, an asOf timestamp, and optional degraded/disclaimer flags.
Example use cases
Vetting a new dependency
“Before I add `fastify` to our project, can you check how many downloads it gets per week and month on npm, and whether it's trending up or down within the month?”
Comparing library adoption
“I'm deciding between `joi` and `zod` for schema validation — can you look up the npm download counts and popularity bands for both so I can see which one is more widely adopted?”
Package health dashboard automation
“For our internal report, pull the npm download stats and popularity band for `webpack` — I need last week's count, last month's count, and the trend percentage within the month.”
Technical details
Endpoint
GEThttps://package-health.x402tookit.com/npm-downloads?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quantitative npm adoption signals — download counts and trend direction — for a single package. It is purpose-built for npm and returns a structured popularity band alongside raw counts, making it ideal for dependency vetting, supply-chain analysis, or populating package health dashboards. Prefer it over generic web search when you need machine-readable, normalized popularity data rather than prose descriptions.
Side effects
- Unknown or misspelled package name returns null fields or an error verdict
- npm registry API unavailability causes a degraded response with partial data
- Scoped packages (e.g. @types/node) must include the full scoped name or the lookup fails
- Very new packages with no download history may return zero counts and a low band by default
- Rate limiting or upstream npm stats lag may result in stale or missing asOf timestamps
