Riddles API vs Agify: common questions

Which is more reliable, Riddles API or Agify?

Only Agify 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 Agify need an API key?

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

Can I call Riddles API and Agify from the browser?

Yes — both Riddles API and Agify 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 Agify free for commercial use?

Riddles API has unclear commercial terms, and Agify allows commercial use on its free tier. 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.
