## 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 saylor-innovations-pub-dev-package-info-5577466b
```

Example prompt: Can you look up the pub.dev info for the 'dio' package — I want to know the latest version, its license, how many likes it has, pub points, and which platforms it supports?

## When to prefer this

Use this endpoint when you need structured, up-to-date pub.dev package metadata (version, license, popularity signals, platform support) without scraping pub.dev yourself. Prefer it over manual browsing or GitHub README parsing when you need machine-readable stats for Dart or Flutter packages specifically.

## Known failure modes

- Package name not found on pub.dev — returns 404 or empty result
- Misspelled package name yields no results
- pub.dev upstream unavailable — may return timeout or 5xx error
- Package exists but has been discontinued or unpublished — may return stale or missing data
