This is the beginning of the notmuch library as well, with its interface in notmuch.h. So far we've got create, open, close, and add_message (all with a notmuch_database prefix). The current add_message function has already been whittled down from what we have in notmuch-index-message to add only references, message-id, and thread-id to the index, (that is---just enough to do thread-linkage but nothing for full-text searching). The concept here is to do something quickly so that the user can get some data into notmuch and start using it. (The most interesting stuff is then thread-linkage and labels like inbox and unread.) We can defer the full-text indexing of the body of the messages for later, (such as in the background while the user is reading mail). The initial thread-stitching step is still slower than I would like. We may have to stop using libgmime for this step as its overhead is not worth it for the simple case of just parsing the message-id, references, and in-reply-to headers.
