I want to add a method for my bot protection project that allows certain rules, one of these rules will be that the current IP belongs to Tor, not because connections from Tor are bad but rather to provide customization options (like disabling JS).

I can’t find a free solution without an API key that is fast enough to fulfill the requirements.

I found Tor Exonera: https://metrics.torproject.org/exonerator.html but there doesn’t seem to be an API for it.
