SuperHeroes vs CheapShark: common questions

Which is more reliable, SuperHeroes or CheapShark?

Only CheapShark 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 SuperHeroes and CheapShark need an API key?

CheapShark needs no key, while SuperHeroes requires a free API key. If you want to start calling without signup, reach for CheapShark first.

Can I call SuperHeroes and CheapShark from the browser?

Yes — both SuperHeroes and CheapShark 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 SuperHeroes and CheapShark free for commercial use?

SuperHeroes has unclear commercial terms, and CheapShark 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.
