I would assume they are at least thinking about an API, as it's fairly easy to construct/what they are doing is easily portable elsewhere (Think Medium like comments all over the place).
With this said, nice work.

- Embedding in personal blogs - this is probably best achieved by a simple embed code (which I'm planning to use my gem to build), rather than a full API
- Commercial use - for instance, Spotify (or competitor) might like to display rich lyrics in-app.
The situations which would demand a full-on API, I suspect, would be commercial use. Thus, I'd imagine that any API they build will be private and commercial, providing a (first?) revenue stream.
