## 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 saylor-innovations-npm-package-report-f08e02e8
```

Example prompt: Can you pull the npm package report for react — I want to know the latest version, its license, how many dependencies it has, and whether it's been deprecated?

## When to prefer this

Use this endpoint when you need a quick structured metadata snapshot of an npm package's latest release — version, license, dependencies, and deprecation status — without downloading or executing any package code. Prefer it over general web search when you need machine-readable, normalized package metadata for automated decision-making (e.g. license compliance checks, dependency auditing, or compatibility verification).

## Known failure modes

- Package not found on npm registry — returns an error or empty report
- Scoped package name malformed (missing @scope/ prefix) — may return incorrect or no results
- Private or unlisted packages are inaccessible — returns not found
- Network or registry downtime — endpoint may return a timeout or upstream error

## How this service works

Inspect the latest npm package release: version, license, dependency counts, engine requirements, deprecation notice and source links. Does not download or execute package code.

## Output

Returns a JSON object containing the package name, latest version, license (or null), full dependency map, dependency count, peer dependencies, engine requirements, deprecation notice (or null), warning signals, source URL, and a timestamp of when the data was retrieved.
