return str(result.inserted_id)

Currently create_document returns a document ID rather than one or more documents like the other non-destructive operations. The resulting ID has to be passed to get_document for the relevant API endpoints. Is this behavior intentional? If so, I would recommend adding a comment explaining why, or if not, updating the function to return the result of calling get_document with the new ID as a parameter.

This is the default functionality of the mongo API. The MongoIO class is a simple wrapper, and making the call to get document leaves room for that method to implement enrichment in a consistant manner.

I believe that the code does call get_document at the service level. The service level code is responsible for the business logic of rendering the object with any required enrichments - doing lookups or other validation/summaization in the service.get_document method allows the service method to call get_document and do this enrichment in a consistant way. The API does return the updated document, the Service layer is responsible for processing the document, and the MongoIO layer is a simple wrapper around a few mongo opperations.
