EverySolve CAPTCHA API

Slider CAPTCHA API

EverySolve's Slider CAPTCHA API returns a numeric answer for your challenge workflow. Send POST /api/v1/captcha with type set to slider and the inputs listed below.

A slider task uses a background image and a separate puzzle piece to calculate how far the piece should move. It returns distance in pixels, not a coordinate, percentage, token, or drag trajectory. The caller creates the interaction path.
