## 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 ajv-npm-package-install-lifecycle-hooks-315299ac -d '<json body>'
```

Example prompt: Can you pull the install lifecycle hooks for the ajv npm package, version 8.12.0, so I can review what scripts run on install before I add it to our project?

## When to prefer this

Use this endpoint when you need to programmatically inspect the install lifecycle hooks of the ajv npm package (or an overridden package/version) for integration auditing, security review, or upgrade planning — particularly in agentic workflows that need npm registry metadata without manually querying the npm registry.

## Known failure modes

- Package name not found in npm registry — returns error or empty result
- Invalid version string — returns validation error
- Rate limiting or payment failure via x402 protocol — request rejected
- Registry metadata unavailable for specified version — incomplete result
