About

SF Bay 511 (BYOK) lets an AI assistant read your own SF Bay 511 data through the SF Bay 511 API with a key you supply (API key). Read-only: 12 tools (list_transit_operators, list_gtfs_feeds, list_transit_lines, list_transit_stops, get_line_timetable, list_transit_holidays, get_stop_arrivals, get_scheduled_departures, list_service_alerts, list_traffic_events, list_work_zones, list_toll_programs). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.511.org. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by SF Bay 511. SF Bay 511 and its logos are trademarks of their owners and are used only to say which service the connector works with.

Sources: Live from the SF Bay 511 API (api.511.org) with a BYOK key; documentation: https://511.org/open-data/transit. Endpoints checked against that documentation on 2026-10-16.
