How the detector works
Behind the scenes we issue a single request to the target URL through the Scrappey detection backend. Every response is fingerprinted against signatures for the major anti-bot vendors — headers like cf-ray, x-datadome, x-iinfo, cookies like _abck, _pxhd, visid_incap, and challenge-page markers like /cdn-cgi/challenge-platform/. Each rule contributes to a confidence score, and the top match plus geo are returned along with a ready-to-use Scrappey API body.
No data is stored — every check is live and the result is fresh.
