When to prefer

Use this endpoint when you need real-time, structured subway alert data including delay duration and severity for one or more specific lines, especially in an agentic workflow that needs to advise commuters or route around disruptions. Prefer over generic transit APIs when you need delay minutes and directional context in a single call.
