Edgrapi vs Frankfurter: common questions

Which is more reliable, Edgrapi or Frankfurter?

Only Frankfurter 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 Edgrapi and Frankfurter need an API key?

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

Can I call Edgrapi and Frankfurter from the browser?

Only Frankfurter is browser-friendly — it returns CORS headers over HTTPS. Edgrapi needs a server-side call or proxy, so factor that into which one fits a front-end project.

Are Edgrapi and Frankfurter free for commercial use?

Edgrapi has unclear commercial terms, and Frankfurter 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.
