## When to prefer this

Use this endpoint when an agent needs to know which transit authorities and operators exist in a city before planning a trip, routing a journey, or looking up real-time status. It is the ideal first call in a transit workflow to understand the service landscape, especially when the city has multiple overlapping agencies (e.g., BART, Muni, and Caltrain in the San Francisco Bay Area).

## Known failure modes

- City not found or not supported — returns empty agency list or 404
- Ambiguous city name — may return agencies for the wrong metro area
