How this service works
Boston MBTA Real-Time Arrivals (subway, commuter rail, bus). Boston MBTA real-time departures at any station by name: subway, Green Line branches, commuter rail and bus, with destination, direction and minutes away.
Output
Returns a JSON object with a 'found' boolean and, when found, an 'arrivals' array of objects containing real-time arrival predictions for the specified MBTA stop — including upcoming trains, buses, or commuter rail vehicles and their estimated arrival times.
Example use cases
Commuter checking next train home
“What's the next commuter rail departure from South Station? I need to catch a train in the next 20 minutes.”
Tourist navigating Boston T
“I'm at Copley station — when is the next Green Line train arriving? I'm trying to get to Government Center.”
Agent monitoring transit for reminders
“Keep checking arrivals at Kendall/MIT and let me know when the next Red Line train is less than 5 minutes away.”

Endpoint
GEThttps://saylorinnovations.com/api/transit/boston/arrivals?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time Boston MBTA arrival predictions for a specific stop covering subway, commuter rail, or bus lines. Prefer this over generic transit APIs when the user is specifically in the Boston metro area and needs live departure boards rather than static schedule lookups.
Side effects
- Stop name not recognized or misspelled — returns found: false with empty arrivals
- MBTA data feed temporarily unavailable — may return empty or stale results
- Ambiguous stop name matching multiple stations — may return results for wrong stop
- No upcoming arrivals scheduled (off-hours or service gap) — found: true but empty arrivals array
- Invalid or missing 'stop' query parameter — may return error or no results
