Sources and licenses
Where the data comes from, and what you may do with it.
The database and API
Our own work is released under CC0 1.0: the database as a compilation, the API, and the facts contributed here. That means public domain: use it in your own apps, commercial or not, with no attribution required and no warranty of any kind.
CC0 covers only what we hold the rights to. Facts, descriptions, and photos taken from other sources keep those sources' licenses, listed below and returned with the data. If you show our data, carrying the source and license along is the right thing to do, and for some sources it is required.
The facts
Facts come from four kinds of source, each listed by GET /v1/sources with its license:
| Kind | Examples | Terms |
|---|---|---|
open_data | Wikidata, Wikimedia Commons | CC0 and Creative Commons; carry the license and attribution along |
manufacturer | Publishers' shops and product pages | Factual data; descriptions and photos are the publisher's and shown with permission |
community | People submitting through this site | Contributed to be shared under the same terms as the rest |
other | Card databases such as Scryfall | Each has its own terms, linked from the source |
Each field's source is in the item's provenance, so you can tell where a number came from and decide whether to use it.
Photos
Each photo has its own license and attribution in the API. Carry both along wherever you show it. A null license means all rights reserved: show it only as part of using this API.
