How to detect KulbyBot
KulbyBot signs its requests, so you detect it by verifying the cryptographic signature on each request. A valid signature proves the request came from Kulby; a copied user agent without the signature does not.

Yes. KulbyBot signs its requests cryptographically, which is the strongest way an agent can identify itself.

What does the Verisoul API return for KulbyBot?
