How to detect C99Bot
C99Bot signs its requests, so you detect it by verifying the cryptographic signature on each request. A valid signature proves the request came from Channel99; a copied user agent without the signature does not.

What is C99Bot?
C99Bot is a crawler run by Channel99 that signs its requests.
Does C99Bot identify itself?
Yes. C99Bot signs its requests cryptographically, which is the strongest way an agent can identify itself.

What does the Verisoul API return for C99Bot?
Every session Verisoul identifies as C99Bot carries an agent block with id "c99bot", name, provider, type "crawler", detection_method "signed" and the detection_signals used (cryptographic, behavioral). Build rules on the id, type and detection method.
