Jev Decision ($0.005/call)
Jev Decision ($0.005/call): Ask Jev (TypeSafe System One) typed questions about one state and get numbers back, not text: noul answers the probability a yes/no is yes; choice picks an option with a probability for every option; score places the state on an ordered scale of levels with a probability for every level. Same body and answer as TypeSafe's POST /v1/systemone (model optional, state as text or JSON, questions keyed by your ids), so their docs and SDK question helpers apply; pay
