Frequently asked questions

We solve both invisible and visible MTCaptcha widgets via the standard createTask endpoint. Pass websiteURL + websiteKey (the sitekey field on the MTCaptcha mtcap-init tag).

Typical solve time is 5–8 seconds. Tokens stay valid for around 90 seconds after issue — submit your form within that window for the highest acceptance rate.

No fixed per-key cap. Concurrent task throughput scales with your plan; the dashboard exposes a real-time tasks-in-flight counter so you can right-size load.
