Spark API Pricing
The API is free to try and also free for brokers and agents (and apps serving them) using their own listings, contacts, or other data. The Spark Store option streamlines access to data from all MLSs using the Platform and is ideal for developers wanting to create and market an app or service to all brokers and agents. The final set of plans is for those who just need access to data from one or a few specific MLSs to build an IDX site or other product for a specific agent or broker, or for apps not sold through the Spark Store.
