# What Is MTGJSON?

MTGJSON is an open-source project that catalogs all Magic: The Gathering cards in a portable format. A dedicated group of fans maintains and supplies data for a variety of projects and sites in the community. Using an aggregation process we fetch data between multiple resources and approved partners, and combine all this data in to various JSON files that you can learn about and download from this website.

Version 5.0.0 Announcement As of MTGJSON5, and going forward, web-served files will be available via a version specific "Web API" path: /api/v5/* . If your project depends on the web-served files please update your project to the new API as soon as possible. During the transition to v5, all v4 API routes are still available at: /files/* . For more information, see the Changelog. We now offer file verification with SHA-256. Every file has a SHA-256 file available at the same API location with an appended .sha256 format. For example: https://mtgjson.com/api/v5/AllPrintings.json.sha256 . Vanishing 3 (This message enters the website with 3 time counters on it.
