How do you detect Kater?

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

What is Kater?

Kater is an automated service from kater that signs its requests.

Does Kater identify itself?

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

Can a bot pretend to be Kater?

Not convincingly. A bot can copy Kater's user agent, but without kater signing keys its requests fail verification and it is not labeled Kater.

How common is Kater?

Very uncommon. Rare, brand new, or not seen on Verisoul traffic yet.

What does the Verisoul API return for Kater?

Every session Verisoul identifies as Kater carries an agent block with id "kater", name, provider, type "other", detection_method "signed" and the detection_signals used (cryptographic, behavioral). Build rules on the id, type and detection method.
