I built a free, open-source dictionary API for developers who need quick word lookups without authentication or paywalls. Powered by Wiktionary, the API returns definitions, parts of speech, pronunciations (IPA), and examples in clean JSON. It’s intended for side projects, demos, learning apps, or anywhere you need dictionary data without extra friction. Feedback on API design and missing fields is very welcome.

Hey Product Hunt 👋 I built this because most dictionary APIs I came across required signups, API keys, or payment—even for small side projects. This API is free, open-source, and powered by Wiktionary. It returns definitions, parts of speech, pronunciations (IPA), and examples in clean JSON, with no authentication required. I’d really appreciate feedback on: - API response shape - Missing fields developers usually expect - Anything that would make this more useful Happy to answer questions and hear suggestions. Thanks for checking it out!
