Local marketplace Zaarly has launched a Zaarly API for adding Zaarly buttons to any website. "Zaarly Anywhere" allows users to request products from someone nearby, such as from simple errands to complex products.
Strutta provides a platform to "engage your audience and convert fans to customers." It does this by launching and managing contests, sweepstakes, coupons, promotions, and by providing the Strutta API. For example, Crate & Barrel ran a wedding contest to drive couples to set up their wedding registries at the company, and featured friends and families of the contestants voting on the results to generate increased customer involvement.
