Need your captchas to be input in Case-Sensitive way?
By default, we will not decode captchas in Case-Sensitive way. But however, we support that. If you need that to be done, you need to contact us and tell us your key and requirement, we will enable your key for that feature. And in future, if you still need that feature to be enabled, you may need to fill credits on your old key, instead of buying a new key.
Will I get refund when captcha is not input correctly?
In short words, yes. In details, our service will charge you for a captcha input only if positive feedback is reported or no feedback is reported. And so if the software you are using has implemented the feedback API, you will never be charged for incorrect input.
