A clean, family-friendly jokes API. Fetch a random joke — or several at once — as a single-line one-liner or a two-part setup-and-delivery, filtered by category (Programming, Misc, Pun, Spooky, Christmas); search for jokes containing a specific word; and list the available categories. Safe-mode is always enforced and the offensive "Dark" category is excluded, so every joke is workplace- and family-safe. Ideal for chat and Discord bots, websites and apps that want a touch of humour, loading screens, and developer tools. Built on JokeAPI.
