## 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 koa-npm-package-install-lifecycle-hooks-9fc9bbe2 -d '<json body>'
```

Example prompt: Can you fetch the install lifecycle hooks from the npm registry for the koa package, version 2.14.2, so I can review what scripts run during installation before I add it to the project?

## When to prefer this

Use this endpoint when you need to inspect the specific install lifecycle hooks (preinstall/postinstall scripts) defined in a koa npm package version before integrating or upgrading, particularly for security auditing or CI/CD pipeline planning. Prefer this over general npm search tools when you specifically need lifecycle hook data rather than general package info.

## Known failure modes

- Unknown package version returns 404 or empty result
- Invalid package name format returns validation error
- npm registry unavailable causes timeout or 503
- Non-existent version string yields no metadata
