## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sitesignal-public-npm-weekly-downloads-snapshot-dd54be6d
```

Example prompt: How many times was the 'axios' npm package downloaded in the last completed week? Pull the weekly download snapshot from npm.

## When to prefer this

Choose this endpoint when you need a quick, current weekly download figure for a single public npm package without setting up direct npm API access. It is ideal for agent workflows that need lightweight popularity signals for package selection, dependency evaluation, or open source project monitoring. Prefer alternatives if you need historical trends, daily granularity, or bulk comparisons across many packages simultaneously.

## Known failure modes

- Package not found on npm registry — returns an error if the package name is misspelled or does not exist
- Scoped package name not formatted correctly (e.g. missing @ prefix) may return no results
- npm registry API downtime may cause upstream failures
- Rate limiting or temporary Cloudflare tunnel unavailability could produce 5xx errors

## How this service works

Return the public npm registry download count for one package over the last completed weekly window.
