Yep. Seems likely. An API is another one of those "you have to support this forever" things, so it better make sense from a business perspective. I'm just as excited about having a full suite of read APIs as write ones.
I should say though that we already offer a number of things that are API-like. For example, you can already programmatically pre-fill a new Pen: https://blog.codepen.io/documentation/api/prefill/ and RSS feeds are essentially an XML API: blog.codepen.io/documentation/api/rss-feeds
It's fairly common, when people ask us for API access, for us to ask what the use-case is, and to have it already be covered by something we have.
