Spark RESO Web API

aid: spark-platform:spark-reso-web-api
name: Spark RESO Web API
description: 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.
