Spark Platform gives developers a way to connect with Multiple Listing Services (MLS) to provide software tools for over 250,000 brokers, real estate agents and their customers. Spark does this by providing an API, store and app bar to create a real estate software ecosystem. The Spark API allows authorized MLS members to request data through developer applications according to the permissions and license requirements of the MLS. This data is categorized by listings, contacts and market stats. The API uses RESTful calls and responses are formatted in JSON.
