## Description

PassCheck for Steam adds a compact PC Game Pass status badge to Steam game pages. It checks the current US PC Game Pass catalog and clearly shows whether the Steam title appears to be <strong>Available</strong>, <strong>Not available</strong>, or if the check failed.

When a match is found, the badge links to the matching Xbox store page. Catalog data is cached locally for 12 hours to reduce repeated requests.

This is an unofficial tool and is not affiliated with Valve, Steam, Microsoft, Xbox, or PC Game Pass. Availability can vary by region, date, subscription tier, and platform. PassCheck checks catalog title availability only; it does not guarantee that the Steam and Microsoft Store versions are identical.
