TL;DR — QUICK ANSWER

reCAPTCHA Solver API is NOW RELEASED and ACTIVE on CaptchaKings! Automatically solve Google reCAPTCHA v2 Checkbox, 3x3 Tile Grid (per-tile classification for traffic lights, fire hydrants, crosswalks, buses, bicycles), 4x4 YOLO Grid (instance segmentation for large multi-cell objects), and token bypass for v3 & Enterprise. CaptchaKings (captchakings.com) delivers solutions at $0.001 per solve ($1.00 / 1,000 solves) with sub-350ms solving speed, 99.9% uptime SLA, and direct REST API integration at https://captchakings.com/api/recaptcha.php plus standard in.php/res.php token solving.

Supported reCAPTCHA Challenge Types

All challenge types are available in production today with 99.2% accuracy:

3x3 Tile Grid Classification

Classifies 9 tiles against challenge title (traffic lights, buses, fire hydrants, bicycles, motorcycles). Returns click tile indices [0-8].

grid: "3x3"

4x4 YOLO Grid Segmentation

Instance segmentation for large objects spanning across multiple squares (crosswalks, bridges, vehicles). Returns ordered indices [0-15].

grid: "4x4"

Dynamic Replacement Tiles

Support for fading/reloading challenge tiles with focus_tiles parameter to solve iterative 3x3 puzzles in continuous flows.

focus_tiles: [0, 4, 8]

reCAPTCHA v2 Checkbox

Standard "I'm not a robot" checkbox challenge solved via direct AI click simulation or token bypass.

v2 Checkbox

reCAPTCHA v2 Invisible

Background verification without user interaction, returning valid g-recaptcha-response token.

Token Bypass

reCAPTCHA v3 & Enterprise

High-score human emulation (0.7 - 0.9 score) designed for enterprise firewalls and strict bot detection.

Score 0.7 - 0.9
