Better to use or EC2 for persistent browser. 9. Managing Cost and Scale | Approach | Cost | Speed | Accuracy | |----------|------|-------|----------| | AWS Rekognition | $0.001/image | Very fast | Low (only simple text) | | 2Captcha (API) | ~$1.50/1000 | 10–20 sec | High (human solvers) | | Custom ML (SageMaker) | High (training + inference) | Fast | Medium (site-specific) | | Browser automation (EC2) | $0.01/hour | Slow | Depends on solver service |

~$1.50 per 1000 CAPTCHAs (2Captcha) + Lambda execution cost. 7. Using AWS Rekognition for Simple CAPTCHAs For basic text-based CAPTCHAs (not modern ones):
# 3. Poll for result captcha_id = submit_res.json()['request'] solution = None for _ in range(30): result = requests.get(f"http://2captcha.com/res.php?key=api_key&action=get&id=captcha_id&json=1") if result.json()['status'] == 1: solution = result.json()['request'] break time.sleep(2) Better to use or EC2 for persistent browser
# 2. Submit to 2Captcha (external service) api_key = "YOUR_2CAPTCHA_KEY" submit_res = requests.post("http://2captcha.com/in.php", data= "key": api_key, "method": "base64", "body": img_data.encode('base64'), "json": 1 )
