Agencies

GTFS-Realtime

GTFS-Realtime is a standard. Integrating it is not.

Every agency has its own endpoint, auth scheme, and data quirks. Some need API keys. Some rate-limit at 1 req/min.
Feed URLs change without notice. Uptime varies. Protobuf decoding fails silently on schema mismatches.
Your agent needs one normalized API, not a spreadsheet of 113+ feed URLs to maintain.

GET https://transit.motioninfo.com/api/feeds

This is a live response from the API. Free, no auth required. 10 req/min.
