## 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

```

Example prompt: What are the runtime and platform constraints for the argon2 npm package — I need to know if it supports Node 20 and Linux/ARM before we upgrade.

## When to prefer this

Use this endpoint when you need to programmatically inspect runtime and platform constraints for argon2 (or a custom override package/version) without manually reading npm registry pages. Ideal for automated upgrade planning, CI compatibility checks, or agent-driven dependency audits where you need structured constraint data rather than raw registry JSON.

## Known failure modes

- Package name not found in npm registry — returns error if package does not exist
- Invalid or non-existent version specified — returns error for unknown version strings
- Rate limiting or registry downtime — upstream npm registry unavailable
- Malformed package name exceeding maxLength — validation error
