REST API for setting up Email Digests?

For anyone else stumbling on this thread, here is some widget API JS code that will create a new group subscription and return the subscription info as JSON.  This code returns JSON instead of HTML and would be called using the /api.ashx/v2/scripted REST endpoint.

core_v2_page.SetContentType('application/json');

/* normally these would be passed in, but for demo purposes they are hard-coded */
var context = "group";
var contextId = 6; // the group ID
var frequency = 7; // # of days - 0, 1, 7

var sub = core_v2_emailDigest.Create(context, contextId, frequency);

/* if we needed to update an existing sub, we would do this */
// var existingSub = core_v2_emailDigest.GetByGroup(contextId);
// var sub = core_v2_emailDigest.Update(existingSub.Id, frequency);

/* return all of the sub properties as a JSON string*/
return JSON.stringify({
    id: sub.Id,
    userId: sub.UserId,
    context: sub.Context,
    contextId: sub.ContextId,
    dateCreated: sub.DateCreated,
    frequencyInDays: sub.FrequencyInDays,
    nextSendDate: sub.NextSendDate
});
