Spark RESO Web API is one of 3 APIs that [Spark Platform](https://apis.io/providers/spark-platform/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include RESO, OData, MLS, Property Listings, and Real-Estate. The published artifact set on APIs.io includes API documentation, an API reference, and authentication docs.

Spark's implementation of the RESO Web API, exposed as an OData service at the /Reso/OData endpoint and serving data shaped by the RESO Data Dictionary. Version 3 is the recommended service root; versions 2 endpoints remain documented. Resources are Property, Member, Office, Media, OpenHouse, Room, Unit, Green Verification, Power Production and Lookup. The OData $metadata document at https://replication.sparkapi.com/Version/3/Reso/OData/$metadata is the machine-readable contract, but it is not anonymously retrievable — it returned HTTP 401 on 2026-07-26. The same API keys used for the Spark API authorize this endpoint.
