NuCaptcha Programming API's

Most websites can get NuCaptcha running from an API install in about 10 minutes, followed by 1-2 hours of customization. We're here to help, so if you have any questions please contact us!

NuCaptcha is currently available in PHP, .NET, and Java. We're putting the finishing touches on the NuCaptcha API for many other languages and platforms -- so let us know what you need and we'll get it to you ASAP.

Please see our General Questions and FAQ, which may already have the answer to any questions you might have. This is a good first stop for answers.
