Wikidata

Wikidata is a knowledge base that is open to all of humanity to explore, edit and to improve. It is a product of Wikimedia, a foundation that also manages platforms like Wikipedia, Wikionary, etc.

Its API is open for testing and has a through documentation that can be found here.

There is an online sandbox to test the requests online that can be found here.

I've tried to send the requests below (which also are the examples given in the sandbox) through Postman to test it:

• https://www.wikidata.org/w/api.php?action=checktoken&format=json&type=csrf&token=123ABC
• https://www.mediawiki.org/w/api.php?action=edit&format=json&title=Test&text=article%20content&summary=test%20summary&baserevid=1234567&token=%2B%5C

The data in wikidata could also be queried using the sparql endpoint.
