hCaptcha Solver API — Token & Image Bypass
hCaptcha is the privacy-first alternative to reCAPTCHA, used by Cloudflare, Discord and Epic Games to gate signups and payments. CaptchaSonic returns a valid hCaptcha token through the HCaptchaTask endpoint — supporting checkbox, invisible and hCaptcha Enterprise (rqdata) flows — typically in 6–12 seconds.
# CaptchaSonic — hCaptcha (Python)
import requests
requests.post('https://api.captchasonic.com/createTask', json={
'clientKey': 'YOUR_API_KEY',
'task': {
'type': 'HCaptchaTask',
'websiteURL': 'https://hcaptcha.com',
'websiteKey': 'a5f74b19-9e45-40e0-b45d-47ff91b7a6c2',
'proxyType': 'http',
'proxyAddress': '1.2.3.4',
'proxyPort': 8080
}
})
# Poll /getTaskResult until status == 'ready'; solution.token is the hCaptcha token.Why use Sonic for hCaptcha + hCaptcha Enterprise?
Built for speed, reliability, and easy integration.
Enterprise + invisible
HCaptchaTask handles standard hCaptcha, invisible widgets, and hCaptcha Enterprise via the optional enterprisePayload and rqdata fields.
6–12s typical solve
Token solves complete in 6–12 seconds; image classification via PopularCaptchaImage finishes in under one second.
Proxy or proxyless
HCaptchaTaskProxyless removes the need for residential IPs; switch to HCaptchaTask + proxy fields for high-friction Cloudflare and Discord targets.
Async polling pattern
createTask returns a taskId; getTaskResult polls until the hCaptcha token is ready — the SDK wraps the loop into a single awaitable solve() call.

Frequently asked questions
hCaptcha is the privacy-first CAPTCHA that replaced reCAPTCHA on most Cloudflare turnstile-precursor pages, Discord, Epic Games and many high-traffic signup flows. It comes in checkbox, invisible and Enterprise (rqdata) modes — all three share the same h-captcha-response token format.
Yes. Standard hCaptcha and hCaptcha Enterprise share the HCaptchaTask endpoint — Enterprise tasks accept the additional enterprisePayload and rqdata fields the protected page generates. Pass them through on createTask and CaptchaSonic returns a valid token in the same 6–12 second window as standard hCaptcha.
Yes. Set task.type to HCaptchaTaskProxyless and pass only websiteURL + websiteKey. For higher-friction sites with strict TLS fingerprinting (Cloudflare, Discord) switch to HCaptchaTask with the proxy fields populated — CaptchaSonic then routes the solve through your residential IP for higher acceptance.
CaptchaSonic bills hCaptcha per 1,000 successful solves with no monthly subscription. Enterprise tasks are the same per-solve rate as standard hCaptcha. Failed solves are auto-refunded — start with the free trial in the dashboard to benchmark your traffic mix.
