Cotality's developer platform gives technology teams direct access to the property data, analytics models, and AI tools that power the U.S. real estate, mortgage, insurance, and enterprise data industries. This page explains what the platform covers, how products are organized, and what to expect at each stage of the product lifecycle. *** ## What this platform covers Cotality maintains the largest independent dataset of U.S. residential and commercial property records — covering more than 150 million properties, updated continuously from county assessors, MLS feeds, permit filings, satellite imagery, and climate models. The developer platform exposes this data through four integration layers: | Layer | What it is | Best for | | --------------- | --------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------ | | **AI Agents** | Conversational agents that execute multi-step business workflows in natural language | Teams building AI-powered automation for appraisal, compliance, or vendor management | | **MCP Servers** | Model Context Protocol endpoints that LLMs and AI assistants can call at runtime to retrieve live property data | Teams embedding Cotality data into AI products, copilots, or agent pipelines | | **REST APIs** | Standard HTTP endpoints returning structured JSON for property data, market analytics, risk scores, and more | Teams building traditional product integrations or data pipelines | | **UI Widgets** | Embeddable components for property search and data display *(roadmap)* | Teams building consumer-facing products | *** ## How the platform is organized Rather than navigating by protocol or data type, this portal is organized around **who you are building for** and **what business outcome you need**. ### Solutions by industry Each industry section explains the relevant use cases, maps Cotality capabilities to business workflows, and gives you a clear path to implementation: * **[Finance and mortgage](/solutions/mortgage-valuation)** — for lenders, AMCs, and appraisers * **[Property insurance](/solutions/property-insurance)** — for underwriters and claims teams * **[Real estate](/solutions/brokerage-investing)** — for realtors and investors * **[Enterprise data teams](/solutions/enterprise-data-teams)** — for data engineers, data stewards, and platform teams ### AI and developer products The products section catalogs individual capabilities — AI agents, MCP tool sets, and REST API groups — with technical reference, input/output schemas, and code examples. ### Technical reference Detailed API schemas, MCP tool specifications, and integration guides for engineers implementing specific data products. *** ## Product lifecycle stages Every capability in this portal carries a lifecycle label that tells you whether it is safe for production use. See the dedicated **[Product lifecycle](/getting-started/product-lifecycle)** page for the full definition of each stage, what it guarantees, and the current status of every capability. *** ## Access and visibility Content on this portal is organized into two visibility tiers: **Public** — Available without authentication. Covers platform overviews, solution guides, integration patterns, and MCP/API reference documentation. **Gated** *(coming soon)* — Requires a Cotality account login. Will cover pre-release capabilities, UAT credentials, partner-specific documentation, and internal tooling. Gated content is marked with a lock icon in the navigation. *** ## REST APIs In addition to MCP, Cotality's data is available through a full suite of REST APIs. These are suited for traditional server-side integrations, data pipeline ingestion, and hybrid architectures where some components use AI agents and others use direct API calls. Available API products include: * **Property API** — Comprehensive property characteristics, ownership, and assessment data * **Spatial API** — Geographic and boundary data for parcels, neighborhoods, and counties * **Insight API** — Derived property intelligence and scoring models * **Interchange API** — Data exchange formats for title and settlement services * **Location API** — Address normalization and geocoding * **Tax Servicing Data API** — Tax assessment and delinquency data * **WVS API** — Waivers, value scenarios, and desktop appraisal data * **Fraud API** — Property transaction fraud signals and risk indicators * **Underwriting Center API** — Automated underwriting data and decisioning support Interactive API documentation and a live playground are available in the **API Reference** section. *** ## Next steps Browse industry solutions to see which capabilities match your business workflows Obtain OAuth2 credentials and make your first authenticated request Connect to the MCP server interactively and explore available tools without writing code See a working end-to-end Python integration with the Cotality MCP server
