The English Wiktionary is served by the same MediaWiki action API that powers Wikipedia, so you can pull definitions, etymologies and translations as structured JSON. Ask for the extract, wikitext, or any prop you like via query parameters. No key, no signup — just the standard MediaWiki endpoint.

Can I call Wiktionary from the browser?
