Steps Request an API token via the 511.org open-data signup form; the token is emailed after verification Call the GTFS feed-download endpoint with api_key and operator_id to get a static GTFS zip for a specific Bay Area operator Call the GTFS-Realtime vehicle positions endpoint for live vehicle location by agency Alternatively use the Stop Monitoring/Vehicle Monitoring real-time endpoints (Open511/SIRI-style) for XML/JSON arrival and vehicle data Respect the default rate limit (60 requests per hour per token) and request a higher limit from 511 SF Bay developer support if needed
Known gotchas 511.org's API is Bay Area-region-specific (operated by MTC) — it is not a generic nationwide '511' standard The default per-token rate limit (60 req/hour) is easy to exceed with naive polling; cache static feeds instead of re-downloading on every request
