Would be great to have an API. Been passively looking for good poster printers that I could automatically send jobs to, as well as do the fulfillment. Looks slick.

There are many APIs out there. To name a few: CanvasPop, QuickPrints by Walgreens, Kodak Alaris, Print.io, Pwinty, Printzel and others.

CanvasPop isn't really an API, in the Twilio sense. It's more like a glorified affiliate program.

Seconded. I run an online portfolio service that integrates with Fotomoto to sell prints right on the customers' site. Would be interested in adding this as an option.

theprintful.com - does a good job of this.
