Transit Reliability API

You can use this API to query by date and return the number of runs that were observed on the system vs the number scheduled and calculated percentage of those completed runs.
Additionally, you can obtain a copy of the raw data being used by my PowerBi reports for your own analysis.

Authentication is required to use this API: Contact me via Twitter/LinkedIn or E-Mail to request an API key.

Rate Limit: All API Endpoints have a 2 requests per second limit - please keep this in mind and be gentle :)
