Common questions
How is response time measured?
We record the median time to a complete response from our own scheduled checks, not from provider marketing. The figure includes DNS, TLS and the server’s own processing, so it is what you would actually experience.
Does a fast API mean a good API?
No. Latency is easy to measure, which is exactly why it gets over-weighted. Coverage, licensing and whether the provider will still exist next year matter more for most projects.
How often is this list updated?
The catalogue is re-checked on a schedule and this page is generated from the latest results, so entries move in and out as their status changes. 54 APIs match right now.
