## Quick Reference
### Check Balance First
```bash
./solve-captcha balance
```
### Image CAPTCHA
```bash
# From file
./solve-captcha image /path/to/captcha.png
# From URL
./solve-captcha image "https://site.com/captcha.jpg"
# With options
./solve-captcha image captcha.png --numeric 1 --math
./solve-captcha image captcha.png --comment "Enter red letters only"
```
### reCAPTCHA v2
```bash
./solve-captcha recaptcha2 --sitekey "6Le-wvk..." --url "https://example.com"
```
### reCAPTCHA v3
```bash
./solve-captcha recaptcha3 --sitekey "KEY" --url "URL" --action "submit" --min-score 0.7
```
### hCaptcha
```bash
./solve-captcha hcaptcha --sitekey "KEY" --url "URL"
```
### Cloudflare Turnstile

## Finding CAPTCHA Parameters
### reCAPTCHA sitekey
Look for:
- `data-sitekey` attribute in HTML
- `k=` parameter in reCAPTCHA iframe URL
- Network request to `google.com/recaptcha/api2/anchor`
### hCaptcha sitekey
Look for:
- `data-sitekey` in hCaptcha div
- Network requests to `hcaptcha.com`
### Turnstile sitekey
Look for:
- `data-sitekey` in Turnstile widget
- `cf-turnstile` class elements
## Workflow for Browser Automation
1. **Detect CAPTCHA** - Check if page has captcha element
2. **Extract params** - Get sitekey/challenge from page source
3. **Solve via CLI** - Call solve-captcha with params
4. **Inject token** - Set `g-recaptcha-response` or callback
### Example: Inject reCAPTCHA Token
```javascript
// 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 account
- `ERROR_NO_SLOT_AVAILABLE` - Retry in few seconds
- `ERROR_CAPTCHA_UNSOLVABLE` - Bad image or impossible captcha
- `ERROR_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
