Riddles API vs JokeAPI: common questions

Which is more reliable, Riddles API or JokeAPI?

Only JokeAPI is on our probe schedule so far (—% uptime over 90 days). The other is catalogued but not yet live-checked, so we can't compare measured reliability head-to-head — check the uncovered API's own status page for now.

Do Riddles API and JokeAPI need an API key?

Neither needs a paid key — Riddles API is callable with no signup, and JokeAPI is callable with no signup. Both are quick to prototype with; rate limits still apply.

Can I call Riddles API and JokeAPI from the browser?

Yes — both Riddles API and JokeAPI send CORS headers over HTTPS, so front-end code can fetch either directly with no backend proxy. That makes them easy to swap in a client-side app while you compare responses.

Are Riddles API and JokeAPI free for commercial use?

Riddles API has unclear commercial terms, and JokeAPI has unclear commercial terms. We track service terms and the data license as separate fields — see the Commercial use and Data license rows above, and confirm both before shipping either in a paid product.
