## 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 packagist-php-package-health-check-a1096970
```

Example prompt: Can you check the health of the guzzlehttp/guzzle package on Packagist — I want to know if it's still actively maintained, what the latest stable version is, how many downloads it has, and whether it's abandoned?

## When to prefer this

Use this endpoint when you need a quick, structured health assessment of a specific PHP Composer package from Packagist, including abandonment signals, download velocity, license, and GitHub activity. Prefer this over manual Packagist browsing when you need machine-readable verdicts for dependency auditing, CI checks, or automated project health reports. Choose sibling endpoints for npm, RubyGems, NuGet, or other ecosystems.

## Known failure modes

- Package not found on Packagist — returns null or error for unknown vendor/package slugs
- Invalid package name format (must be vendor/package) — query param validation failure
- Packagist API unavailable — upstream timeout or error
- GitHub signals missing if repository is not hosted on GitHub
- Payment failure (x402) — 402 response if USDC payment not provided
