Compass
Compass is a New York City headquartered, tech-enabled residential real estate brokerage founded in 2012 by Robert Reffkin and Ori Allon. The company operates the largest residential real estate brokerage in the United States by sales volume, supporting roughly 36,890 agents and $267 billion in gross transaction value across approximately 250,360 transactions in fiscal year 2025, on $6.96 billion in revenue. Compass builds and operates a proprietary, end-to-end agent platform — an integrated cloud-based suite spanning CRM, marketing center, transaction management, listings, market analytics, the Compass One client dashboard, Compass Lens, AI-powered comparative market analysis, AI-generated video, virtual agent services, and a voice-activated AI assistant — custom-built for residential brokerage workflows. The company has invested over $100 million per year in technology and runs a 500+ person Product and Engineering organization, with engineering hubs that have included Seattle. Compass completed its merger with Anywhere Real Estate on January 9, 2026, combining two of the largest residential brokerage operators in the United States. The Compass platform is internal-facing: it is offered as the operating system for Compass agents and their clients, not as a developer product. There is no public REST API, OpenAPI specification, SDK, or third-party developer portal for the Compass real estate platform; the company's GitHub presence at github.com/urbancompass publishes a handful of internal-tooling open source projects (e.g. Snail, Mussel, hnvm, bazel-toolchain) rather than product APIs.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Compass the way a machine reads it — 2 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Compass scores 10.6/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Compass
Each block below is one kind of artifact we hold for Compass. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
