Frequently asked questions

NextCaptcha is a newer entrant with a thinner SDK surface and limited captcha-type coverage. CaptchaSonic supports every major modern captcha (reCAPTCHA, hCaptcha, Turnstile, GeeTest v4, FunCaptcha, AWS WAF, DataDome, TikTok) with first-party SDKs in six languages.

NextCaptcha's headline rates look low but exclude variable success-rate surcharges. CaptchaSonic's posted per-1k is what you pay — failed solves are refunded.

Yes. The createTask / getTaskResult / getBalance triplet mirrors NextCaptcha's API, so existing SDK code typically swaps with a base-URL change.
