TK Pal: TypeKey + PayPal for PHP

Andre Torrez:

TK Pal is a snippet of PHP code you can place in a PHP enabled page to restrict access to content to TypeKey users who have specifically paid to see that content.

What’s neat — in the way that anything recursive is inherently neat — is that he’s using TK Pal to charge a dollar for access to TK Pal’s source code and documentation. As Torrez describes it, it’s “Kind of like using a robot to build robots.”
