Steps Register for a free API key at api-v3.mbta.com to raise the default rate limit Query the JSON:API-formatted endpoints for routes, stops, trips, schedules, predictions, vehicles, facilities, and alerts Use the predictions endpoint for real-time arrival/departure estimates and the vehicles endpoint for live position Use JSON:API include parameters to embed related resources (e.g., route/stop) in a single request instead of making N+1 calls Use the documented streaming interface for long-lived, low-latency updates instead of polling repeatedly Known gotchas Responses follow the JSON:API spec (data/included/relationships structure) — a naive JSON parser expecting flat objects will misread nested relationships Unauthenticated requests share a much lower rate limit than the default (1,000 req/min) granted with a registered key
