App that uses AntiCaptcha is not working
Please contact your app developer for support: we have no idea how those apps work, and we've probably never seen or even heard of them.
We provide API (application programming interfaces) for developers to integrate into their apps. We take no responsibility for the quality of those apps, nor the number of captchas they might send to us.
I don't know where to enter API key into my app, please help
Neither do we! We're only responsible for delivering the services offered by this website (anti-captcha.com). Anything you download and use on other websites is not within our field of responsibility.
