Finding CAPTCHA Parameters
reCAPTCHA sitekey
Look for:
data-sitekeyattribute in HTMLk=parameter in reCAPTCHA iframe URL- Network request to
google.com/recaptcha/api2/anchor
hCaptcha sitekey
Look for:
data-sitekeyin hCaptcha div- Network requests to
hcaptcha.com
Turnstile sitekey
Look for:
data-sitekeyin Turnstile widgetcf-turnstileclass elements
Workflow for Browser Automation
- Detect CAPTCHA - Check if page has captcha element
- Extract params - Get sitekey/challenge from page source
- Solve via CLI - Call solve-captcha with params
- Inject token - Set
g-recaptcha-responseor callback
Example: Inject reCAPTCHA Token
// After getting token from solve-captcha
document.getElementById('g-recaptcha-response').value = token;
// Or call callback if defined
___grecaptcha_cfg.clients[0].callback(token);
Cost Awareness
- Check balance before heavy automation
- Image: ~$0.001 per solve
- reCAPTCHA/hCaptcha/Turnstile: ~$0.003 per solve
Error Handling
Common errors:
ERROR_ZERO_BALANCE- Top up accountERROR_NO_SLOT_AVAILABLE- Retry in few secondsERROR_CAPTCHA_UNSOLVABLE- Bad image or impossible captchaERROR_WRONG_CAPTCHA_ID- Invalid task ID
Notes
- Solving takes 10-60 seconds depending on type
- reCAPTCHA v3 may need multiple attempts for high scores
- Some sites detect automation - use carefully
- Tokens expire! Use within 2-5 minutes
