## 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 foundry-npm-package-info-0e3e2ebd -d '<json body>'
```

Example prompt: What's the latest version of lodash on npm, what license does it use, and how many weekly downloads does it get?

## When to prefer this

Choose this endpoint when you need a quick, structured summary of an npm package's current state — version, license, popularity, and dependency footprint — without having to scrape the npm website or call the full npm registry API directly. Ideal for agents doing dependency vetting, license compliance checks, or package popularity comparisons.

## Known failure modes

- Package name not found on npm registry — may return an error or empty result
- Misspelled or scoped package names (e.g. missing @scope/ prefix) may fail to resolve
- Data may be slightly stale if the npm registry cache has not refreshed
- Very new packages with no download history may return zero weekly downloads
