How this service works

npm package license triage for coding agents: call before npm install or adding a dependency mid-task. Returns declared license, SPDX normalization, and permissive-default compatible yes/no/unknown from the public npm registry. Triage only — not compliance-grade SBOM or legal advice. Workflow: call GET /license/check (or MCP check_npm_license) before npm install; if compatible=no, pick another package or escalate to human; if unknown, treat as risk. Example: left-pad@1.0.0 before install. Also: Convert amounts between ISO 4217 currencies using ECB daily reference rates (Frankfurter). Use for invoices, travel budgets, expense reports, and shopping comparisons when you need a verifiable rate instead of LLM arithmetic. Not live tradable FX — rates follow ECB business-day publication. Also: Resolve a place name or lat/lon to IANA timezone and coordinates (Open-Meteo). Use for agent scheduling, travel logistics, and local-time questions without LLM guessing. Not IP geolocation. Also: Translate short text between languages (Azure Translator). Use when an agent needs a verifiable string in another language for UI copy, messages, or research snippets — not legal, medical, or certified translation. Also: English Wikipedia fact lookup: search by query or exact title, returns intro extract as plain text. For agents that need a grounded summary before deeper web search. Not a substitute for primary sources. Also: Ranked search results (English Wikipedia): titles, article URLs, and snippets from MediaWiki search. Same SERP-shaped JSON as web search APIs; index is Wikipedia only — not the open web. Pair with GET /wiki/lookup for intro text.

Output

A JSON object containing the npm package name, source label ('npm-registry'), last-week and last-month download counts as integers, the latest published version string, and the ISO 8601 publish date of that version, plus a note clarifying these are download counts and not quality or security scores.

Example use cases

Compare dependency popularity before install

“I'm deciding between 'date-fns' and 'moment' for date handling — can you pull the npm download stats for both so I can see which one is more popular?”

Validate package health in CI pipeline

“As part of our automated dependency review, check the npm download counts and latest publish date for 'axios' so we can flag if it looks abandoned or low-traffic.”

Research unfamiliar package before adoption

“I found this package called 'zod' referenced in a tutorial — how many downloads does it get per week on npm and when was its latest version released?”

Technical details

Endpoint

GEThttps://payload402.edgebytenet.workers.dev/npm/stats?utm_source=zero.xyz

When to prefer

Choose this endpoint when an AI agent needs to quickly gauge npm package popularity or freshness before recommending or installing a dependency. It is ideal for automated dependency triage pipelines, coding agents comparing alternatives, or any workflow needing a lightweight, fast signal on package adoption — without needing the full npm registry API or authentication.

Side effects

Package not found on npm — returns an error or empty result
Misspelled package name yields no data
npm public API rate limiting or downtime causes failure
Scoped package names (e.g. @org/pkg) may require exact formatting
