Ambee vs IPASIS: common questions

Which is more reliable, Ambee or IPASIS?

Both are neck-and-neck — Ambee and IPASIS each measure 0.0% uptime over 90 days on our probe schedule. Reliability here is verified from our own scheduled checks; use the 30-day bars above to see which has been steadier lately.

Do Ambee and IPASIS need an API key?

Both ask you to authenticate — Ambee uses an API key and IPASIS uses an API key. Each key is free to obtain; the Auth and Card-required rows above spell out the signup terms.

Can I call Ambee and IPASIS from the browser?

Neither sends browser-friendly CORS headers reliably, so call Ambee and IPASIS from a server or proxy rather than client-side. The CORS and HTTPS rows above show exactly what we detected for each.

Are Ambee and IPASIS free for commercial use?

Ambee has unclear commercial terms, and IPASIS 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.
