[ 01 ]What it looks like

Nothing for clean traffic; flagged sessions get a kaleidoscope puzzle or an image grid.

[ 02 ]Why it is hard

Two solving paths coexist. The sitekey and token flow covers the widget, while the kaleidoscope variant is a raw-image challenge with its own task type, so an integration that handles only one breaks on a large share of sessions. The risk model is tuned on RU and CIS traffic, which means non-regional exit IPs are challenged far more often than the widget's headline pass rate suggests.

[ 03 ]How we solve it

Send the page URL and the sitekey and we return the smart-token your form post needs. When the page serves the image variant instead, the same account posts the raw challenge to the image task type, so you do not build a second integration. For targets that score foreign IPs down, the proxy task type solves through your own RU or CIS exit.

Questions about this one

$2.18 per 1,000 successful solves for the token flow. The raw-image variants are billed as image tasks at the image rate, so a page that falls back to the kaleidoscope costs less, not more.

Not to get a token, but it changes how often you are challenged at all. SmartCaptcha scores RU and CIS traffic as normal and everything else as unusual, so a matching exit reduces the number of solves you have to buy.

Median 4.9s, 95th percentile 11.0s. The tail is mostly sessions that get the kaleidoscope puzzle rather than passing the invisible check.

Both are invisible-first widgets with a fallback challenge, but the token formats, the task types and the fallback shapes differ. SmartCaptcha's fallback is a puzzle or grid image, and its risk model is regional in a way Turnstile's is not.
