Hi there. So, I'm the author of this article. Anyhow, for our free-tier users we don't provide realtime lookups.
Basically, we'll only return a result if we have a caller ID in our cache. So, if you get a 404 (no output), then try again a few seconds later after we've had time to do the lookup via our backend.
Sorry about that! Realtime lookups are currently restricted to API key users only.
