TransiCast / Rasa - The Web API
TransiCast / Rasa is a public transportation data aggregation platform with a REST API that provides real-time feeds and service network data of North American transit agencies in a single, unified format. TransiCast offers API services for the following metro areas and agencies:
Using TransiCast / Rasa, you get instant reach across multiple metro areas without the need to find the data from various sources and to develop against the various real-time feed formats that TransiCast / Rasa aggregates. Currently, TransiCast / Rasa implements twelve different real-time feed formats and GTFS service network data.
How it works
Think of TransiCast / Rasa as a Gigya for public transportation data. You license the data (sources here), and use TransiCast / Rasa to aggregate your data feeds. TransiCast / Rasa delivers the content of these feeds through a hosted REST API in an unified, integrated data format.

Beyond these samples, the REST API is open for full hands-on test drives. No sign up required (although you can register for the Test on General TransiCast Web Server plan here). Check it out with an open sample key, and code against the REST API. Assuming familiarity with the implementation of client side REST API calls, the documentation should contain all necessary information to get started. Please let us know what you think.
Please note that user facing production calls to TransiCast / Rasa require an application ID on a production plan, and licenses for the transit data, as applicable.
Production setup
"Production" calls to TransiCast / Rasa which you use to provide service to your users require a subscription of a TransiCast / Rasa production plan. We manage this aspect of TransiCast / Rasa through 3scale. With sign-up to a production plan, we:
- • Set up and maintain a dedicated and exclusive instance of the TransiCast / Rasa web server on Google App Engine
- • Provide a dedicated and exclusive application ID
- • Provide monthly updates of the base data (stops, routes) as provided by the original source (transit agencies)
Cost structure
Once production is set up, the following cost elements drive your recurring cost:
- • Base subscription to TransiCast/Rasa: USD 30/month. Billed monthly
- • Usage of TransiCast/Rasa: USD 0.1ct/call for every call beyond 25000. Billed monthly
- • App Engine instance cost, depending on configuration. Google bills directly to you
- • Arrangements with data sources, if needed
Your expected monthly cost, in examples:
Example 1: 500 overall calls to TransiCast/Rasa using a free instance on App Engine: $30 plus 500 * 0.1ct = $30.50
Example 2: 12500 calls to TransiCast/Rasa using a billed, resident instance on App Engine: $30 plus 12500 * 0.1ct plus $30 (est. expense to Google) = $72.50
Example 3: 100800 calls to TransiCast/Rasa using a billed, resident instance on App Engine: $30 plus 100800 * 0.1ct plus $45 (est. expense to Google) = $175.80
You can cancel your subscriptions at any time and for any reason, no questions asked.
