Recycle Keys

Dead Balance? Cash It In.

Got leftover balance sitting on old provider keys? Don't let it rot. Add those keys to uCaptcha — we drain the balance for you and credit your account dollar-for-dollar. That credit can be used on all of uCaptcha — not just the one you bought from.

We use the balance — you get the credit
