OneDrive folder can show files as-if present, but they are not on disk.
I'd like to create a similar folder programmatically. What API does OneDrive client use?

From official documentation: Build a Cloud Sync Engine that Supports Placeholder Files
Note that the Cloud Filter API provides you the API to manipulate Windows 10 1709's NTFS placeholders, but it will not help you build a "sync engine" at all... There's no notion of "synchronization" in this API.
