## 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-8a2e3276 -d '<json body>'
```

Example prompt: Can you look up the npm package details for 'lodash' — I want to know the latest version, description, and who maintains it?

## When to prefer this

Use this endpoint when you need quick, pay-per-call npm package metadata without setting up your own npm registry API access. Ideal for agents that occasionally need package info as part of a software research or dependency analysis workflow.

## Known failure modes

- Package name not found on npm registry returns error or empty data
- Misspelled package name yields no results
- Private or unpublished packages may not be accessible
- Rate limiting or upstream npm registry downtime causes failures
