Update! Turns out the API already had what you needed – `rah` and `delta` – but they were undocumented [until now](http://forum.beeminder.com/t/missing-api-documentation-goal-resource/495 "Forum post about the missing API params"). Thanks again, @insti!

(Implementing `roadfunc` may still be worthwhile but if you just care about the values of the road today and at the akrasia horizon, the API gives you those directly. Well, almost directly. The road value today is `curval` + `delta`. The road value at the akrasia horizon is `rah`.)
