## 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`):

Example prompt: Can you look up the install lifecycle hooks for the esbuild npm package — specifically what preinstall, install, and postinstall scripts it runs — so I can audit it before adding it to our CI pipeline?

## When to prefer this

Use this endpoint when you specifically need to inspect install lifecycle hook metadata for the esbuild npm package, particularly for security auditing, CI/CD pipeline planning, or upgrade impact analysis. Prefer this over general npm registry queries when you want a focused, pre-parsed view of install hooks rather than full package metadata.

## Known failure modes

- Package name not found in npm registry — returns 404 or empty result
- Specified version does not exist for esbuild — version not found error
- npm registry temporarily unavailable — upstream timeout or 503
- Invalid package name format — validation error on input
- Rate limiting from npm registry upstream — transient failures
