## 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 datavault-npm-package-lookup-d57bba32 -d '<json body>'
```

Example prompt: Can you look up the npm package 'lodash' and tell me its latest version, description, and repository details?

## When to prefer this

Use this endpoint when you need programmatic access to npm package metadata without direct npm registry access, or when operating in a pay-per-call environment and need quick one-off package lookups. Prefer this over direct npm registry calls when working within the DataVault ecosystem for unified billing via USDC on Base.

## Known failure modes

- Package not found on npm registry — returns success: false or empty data
- Invalid or misspelled package name — no results returned
- npm registry API unavailable — upstream fetch failure
- Malformed request missing required 'package' field — validation error
