MLS Aligned API provides data from existing data repositories using server-side memory mapping and cloud based technology to simulate a data share and eliminate data replication. The MLS Aligned API brokers data from existing MLS repositories into a single unified RESO payload. The API interprets RESO/OData WEB API queries and returns data directly from the host MLS. The API uses server-side memory mapping techniques and, cloud based microservices to enhance performance of reading LIVE MLS repositories that handles the translation of fields to provide the same payload regardless of the source. MLS data share is the practice of pooling data from more than one multiple listing service (MLS) into a centralized repository.
