CapMonster Cloud

What it does

CapMonster Cloud is a cloud service that recognizes CAPTCHA types such as reCAPTCHA v2 and v3, Cloudflare Turnstile, GeeTest, Amazon WAF, and text CAPTCHAs. It offers a JSON API with official SDKs for C#, Python, JS, GO, and PHP, plus Chrome and Firefox extensions. The site lists per-1000-token prices and success rates for each CAPTCHA type.

CapMonster Cloud is a hosted CAPTCHA solving service for developers and automation work. You send a task through the JSON API and retrieve the result, or you install the Chrome or Firefox extension to solve CAPTCHAs while browsing. The site lists official SDKs for C#, Python, JS, GO, and PHP, and says the API supports other services' APIs even without a direct integration. Pricing is shown per 1000 tokens or images, and the page states you only pay for successfully solved CAPTCHAs. Success rates are listed per CAPTCHA type, ranging from 95% for Yidun to 99% for several others, so check the table for the type you need. The page also mentions a bonus program of up to 15% and an affiliate program of up to 30%. A $0.1 test balance is available on request to support, and ZennoPoster users get 5,000 free captchas for testing. The service is intended for legitimate uses such as testing your own site or recognizing images you provide.
