CoreLogic (Cotality)

CoreLogic — rebranded as Cotality in 2025 — is a property data and analytics company providing real estate, mortgage, tax, hazard, and climate-risk information across approximately 99% of U.S. residential properties plus operations in Australia, New Zealand, the United Kingdom, Canada, Germany, and India. The company was taken private by Stone Point Capital and Insight Partners in June 2021 in a $6B transaction. The primary public developer surface is Trestle (trestle-documentation.corelogic.com / api.cotality.com), which delivers MLS listing, member, office, media, and team data via a RESO Web API 2.0 / OData 4.0 endpoint, a RETS 1.8 endpoint, and a Direct Web API for Matrix CRM and MLO (member loan officer) integrations. Most other Cotality data products — 360 Property Data, Climate Risk Analytics, Discovery Platform — are delivered through cloud data shares (AWS, Databricks, Google Cloud, Azure, Snowflake) and SFTP rather than self-service REST APIs and are gated behind enterprise sales.
