The payment API provider Stripe released a jQuery payment tool, a general purpose library for building credit card forms, validating input, and formatting numbers. The library was developed to support Checkout, Stripe's embeddable checkout widget.
Simple, but extremely useful libraries like this can go a long way to introduce developers to your APIs and put valuable tools into their toolbox, that will help them be successful. Something that can go a long way in establishing a loyalty between you and your developer community.
