Authentication

None — keyless (a User-Agent identifying your app is good practice).

Rate Limits & Notes

• Free; the Wikimedia API asks for a descriptive User-Agent and no heavy bursts.
• Standard MediaWiki API — action=query, action=parse, etc.
• Each language edition has its own host (en.wiktionary.org, fr.wiktionary.org…).
• Content is wikitext — parse it or use the REST HTML endpoints.

FAQ
