MTCaptcha Solver API — Token Bypass
MTCaptcha is the GDPR-aware adaptive CAPTCHA used by banks and SaaS platforms that need EU-compliant bot filtering. CaptchaSonic returns a valid MTCaptcha verifiedtoken via the MTCaptchaTask endpoint — supporting both invisible and visible widget modes — typically in 5–8 seconds with proxyless infrastructure managing IP reputation.
# CaptchaSonic — MTCaptcha (Python)
import requests
requests.post('https://api.captchasonic.com/createTask', json={
'clientKey': 'YOUR_API_KEY',
'task': {
'type': 'MTCaptchaTask',
'websiteURL': 'https://example.com',
'websiteKey': 'MTPublic-XXXXXXXXX'
}
})
# Poll /getTaskResult until status == 'ready'; solution.token is the MTCaptcha verifiedtoken.Why use Sonic for Adaptive proof-of-work token API?
Built for speed, reliability, and easy integration.
Invisible + visible widgets
MTCaptchaTask handles both invisible and visible widget modes — pass the sitekey from the mtcap-init tag and CaptchaSonic returns a verifiedtoken.
5–8s typical solve
Token solves complete in 5–8 seconds; the verifiedtoken stays valid for ~90 seconds after issue — submit your form within that window.
Proxyless by default
Built-in IP reputation pool removes the need to BYO proxies; attach an EU-region proxy only when the target enforces GDPR geo-fencing.
Async polling pattern
createTask returns a taskId; getTaskResult polls until the verifiedtoken is ready — the SDK exposes a single awaitable solve() call.

Frequently asked questions
MTCaptcha is the GDPR-aware adaptive CAPTCHA chosen by EU banks, fintech and SaaS platforms that need bot filtering without exporting user data to Google. It ships visible and invisible widget modes that both return a verifiedtoken. CaptchaSonic solves both via the MTCaptchaTask endpoint.
CaptchaSonic solves both invisible and visible MTCaptcha widgets through the same MTCaptchaTask endpoint. Pass websiteURL + websiteKey (the sitekey field on the page's mtcap-init tag) and CaptchaSonic returns a verifiedtoken ready to inject into your form submission.
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. Failed solves are auto-refunded so you pay only for tokens your backend accepts.
CaptchaSonic prices MTCaptcha per 1,000 successful solves with no monthly subscription or seat fee. Invisible and visible modes share the same per-solve rate. Start with the free trial in the dashboard to benchmark cost and concurrency against your traffic.
