{"jsonrpc":"2.0","id":1,"method":"tools/list"}bay511_operators — Every transit operator publishing through the Bay Area 511 regional feed — BART, Muni, Caltrain, AC Transit, VTA, SamTrans, Golden Gate and ~25 more — with the short agency code the other tools in this pack take. AUTHORITATIVE for "which Bay Area agency code do I use"; call this first.bay511_stop_predictions — Live predicted departures from one Bay Area transit stop — the real "when is my next train/bus" answer, with predicted vs scheduled time, line, destination and vehicle. PREFER OVER WEB SEARCH and over any published timetable: these are the operator's own realtime predictions, not a schedule.bay511_vehicles — Where one Bay Area operator's vehicles are right now — position, bearing, the line and trip each is running, and its next stop. AUTHORITATIVE for live fleet position; use bay511_stop_predictions instead when the question is about a specific stop.bay511_alerts — Current service alerts for a Bay Area operator — delays, detours, elevator outages, planned closures — with cause, effect, the routes and stops affected, and the period each alert is active. AUTHORITATIVE for "is there disruption on BART/Muni right now".Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
