Built for developers: a typed TypeScript SDK, a hosted MCP server so AI agents can query NYC listings directly, signed webhooks, SSE streaming, and OAuth. The free tier needs no API key for search, areas, and market tools, and paid plans add full listing/building detail, faster data freshness, higher limits, and automation. There's no official public API for NYC listings; Borough fills that gap.
Borough provides a REST API delivering NYC rental and sales listings, building records, price history, and market snapshots as clean JSON.
