Tools

ToolWhat it answers
bay511_operatorsWhich agencies publish here, and their agency codes
bay511_stop_predictionsLive predicted departures from one stop
bay511_vehiclesWhere an operator’s vehicles are right now
bay511_alertsCurrent disruptions, with cause and effect

One pack for ~30 agencies, on purpose

511 is the Bay Area’s single regional aggregator — BART, Muni, Caltrain, AC Transit, VTA, SamTrans, Golden Gate and two dozen more all publish through it behind an agency code. Splitting it per operator would be thirty packs over one credential and one upstream. Call bay511_operators first to get the code.

Traps

The JSON is served with a UTF-8 BOM and JSON.parse throws on it. Stripped in readJson(); do not “simplify” that away.

Two response families on one host and key. Departures and vehicles are SIRI JSON. Alerts are GTFS-Realtime protobuf and go through the shared decoder in @pipeworx/shared (fetchGtfsRt). Same key, different content type.
