npm download stats API: daily, weekly and monthly counts

$0.01 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

Download counts of an npm package for the last day, week and month, from the official npm registry API. Use to judge how widely a dependency is used.

When to use it

Run it free (25 free calls) Buy credits by card (from $1) Example result (JSON)

Try it with your own inputs

Package name, e.g. react or @scope/name

Uses one of your 25 free calls. Nothing is charged, and a call that fails is not counted.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://tools.funwords.eu/npm/downloads?package=hono"

Or one of your 25 free calls, no key:

curl "https://tools.funwords.eu/npm/downloads?package=hono&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.

Example result

{
  "package": "hono",
  "lastDay": 450000,
  "lastWeek": 3100000,
  "lastMonth": 13000000
}

From an AI agent (MCP)

Add the MCP server to Claude, Cursor or any MCP client. This tool is npm_downloads, and the first 25 successful calls are free:

Questions

Where do the counts come from?

The official npm registry API.

How do I pay?

Each successful call costs $0.01; failed calls are not charged. The first 25 calls are free. Then pay with card credits (from $1; the key goes in an Authorization header or, for clients that can only fetch a URL, as api_key= in the URL) or per call in USDC over x402 or MPP. No account is needed.
