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

How do you detect Quartr Crawler?

What is Quartr Crawler?
Quartr Crawler is a crawler run by Quartr that signs its requests.
Does Quartr Crawler identify itself?
Yes. Quartr Crawler signs its requests cryptographically, which is the strongest way an agent can identify itself.
Can a bot pretend to be Quartr Crawler?
Not convincingly. A bot can copy Quartr Crawler's user agent, but without Quartr signing keys its requests fail verification and it is not labeled Quartr Crawler.
How common is Quartr Crawler?
Very uncommon. Rare, brand new, or not seen on Verisoul traffic yet.
What does the Verisoul API return for Quartr Crawler?
Every session Verisoul identifies as Quartr Crawler carries an agent block with id "quartr_crawler", name, provider, type "crawler", detection_method "signed" and the detection_signals used (cryptographic, behavioral). Build rules on the id, type and detection method.
