Service Composition for My Screen Capture API

I now have a pretty simple screen capture API. You can pass it a URL and it gives you back a PNG image file of that website. Meeting my definition of a simple utility API. I use this API in my own platform, capturing what websites and applications look like for reference in stories, and other content.

I want to make this valuable utility API available to a wider audience now. I need to compose some tiers of access to my screen capture API, that makes sense to my business goals and how it will be consumed by a variety of users. So far I’ve come up with five levels of access to my API:

That represents the five separate ways I want to allow access to my screen capture API. Now I can configure my 3Scale API infrastructure, define this exact service composition, and the API will handle the rest. When new users sign-up I will route them into one of these service tiers, and manage their access accordingly.

After I get my API management layer configured, I will have to craft a pricing page to educate new users about what type of access is available. In addition to being a post on API Evangelist, you can find the story of my screen capture API over at the research project I’ve setup over on Github.
