This looks like a RNG: I got 0.7, 0.9, and 0.1 successively. It can't make up its mind whether I'm almost certainly not a bot (0.9) or almost certainly a bot (0.1)?
Might very well be. I also get errors on hacker news about "can't process requests that fast". When asking about it (initially because I thought votes didn't work randomly), the limit is a few requests per second. Turns out I click faster than that, either by reading a whole comment thread and making up my mind whose comments were most helpful (to upvote all at once) or by navigating too fast.
That would be a useless site, but that's not how I read it. I understand it as "this is not that Google thinks your account is a bot, it's that this request might be made by a bot. And since you didn't use this site as a normal website, it also doesn't score your type of traffic, just this one request". You might be right, but it really does seem to be doing a request to their API.
Documenting requests' format and their return values is documentation and doesn't require an interactive site that looks totally real and makes you expect a real (rather than a dummy) answer. Which is not to say it's impossible, but it would be weird/unlikely. Usually when there is an example api request in documentation, it's a real (live) request, too, and this isn't even a documentation page.
Come on, how is everyone in this chain so blind. It's literally in bold and the single largest block of content on the page:
NOTE:This is a sample implementation, the score returned here is not a reflection on your Google account or type of traffic. In production, refer to the distribution of scores shown in your admin interface and adjust your own threshold accordingly. Do not raise issues regarding the score you see here.
