  description: 'Welcome to umd.io, the open-source API for University of Maryland data. If you are building a University data-focused app, hack, or project, you’re in the right place. This site will walk you through basic API use and document all supported API calls.


    umd.io is a GETful API. It follows RESTful conventions, but for now, you can only get data – you can’t create, update, or destroy.


    We''re now in version 1! We might add new endpoints or more data to existing responses, but we won''t remove anything without a major version change.


    If you''re looking for the v0 docs, you can find them at https://docs.umd.io/. Please note that v0 is deprecated. It will continue to be supported until at least 2021, but will get no further feature updates, and will eventually be discontinued.


    We are actively looking for contributors! Tweet, email, or otherwise get in touch with us.'

  description: This endpoint lets you get data about bus routes, schedules, stops, locations, and predicted arrival times. The data is provided by NextBus, which monitors buses and gives the data to us via their API. We think our API is easier to use, but our data might be behind NextBus by a few seconds. If your app requires to-the-second bus location info, you can go right to the source. All bus data is copyright University of Maryland
