GTFS Changes and GTFS-RT Debut


As of May 19, 2021, we will be disabling TLS 1.0, TLS 1.1, and 3DES encryption for all APIs, including GTFS, hosted at https://api.wmata.com, leaving only TLS 1.2 for HTTPS encryption. We recommend confirming that your application is able to access WMATA APIs using TLS 1.2 before then.


The collection of data offered here allows developers to create new and innovative applications for the web or mobile devices. We encourage you to integrate Metro data into your applications and mashups to help get people the information they want about getting around. Use of our APIs and other data is free of charge!

API Documentation


Check out the automatically generated API Documentation that describes how to use the APIs and includes code samples in multiple languages. The API Console allows you to directly interact with the API right here in the developer portal.
