Borough is a REST API that provides structured access to NYC real estate data including rental and sale listings, building details, neighborhood boundaries, market statistics, building quality scores, and FCC-backed internet provider availability.

​
What Borough provides

  • Dozens of structured listing fields across summary and detail endpoints, including pricing, concessions, amenities, photos, and freshness metadata
  • Building-level data with amenities, policies, NYC regulatory data, and quality scores
  • First-party photo delivery through /v1/photos/{key} for supported Borough image sizes
  • Likely internet providers with FCC-sourced provider names, technologies, and advertised speeds
  • 349 neighborhoods with encoded map boundaries
  • Market snapshots with inventory, median prices, days on market, and concession rates
  • Building quality scores derived from NYC Open Data (HPD violations, 311 noise, NYPD crime, transit proximity)
  • Live SSE streaming for instant cached + live listing data (Pro+)
  • Persistent watchers that monitor listings, buildings, or searches for changes (Business+)
  • Webhooks for automated notifications on price drops, new listings, and status changes (Business+)
  • MCP server for connecting AI agents directly to NYC real estate data

Free tier covers search, area reference, market snapshots, and photo delivery. The public /v1/health endpoint is also available without authentication, but it is outside Borough’s metered /v1 data surface. Starter and above unlock property details and building data. Pro adds live SSE streaming. Business adds webhooks, persistent watchers, and change notifications.

​
Product surface

Borough keeps its public product pages and service runtime on the same hostname without changing the integration URLs developers depend on.
  • Public site and legal pages live at borough.qwady.app/
  • REST endpoints stay under borough.qwady.app/v1/*
  • MCP remains at borough.qwady.app/mcp
  • OAuth and discovery stay under borough.qwady.app/oauth/* and borough.qwady.app/.well-known/*
  • Webhook subscriptions stay under borough.qwady.app/v1/webhooks/*

​
Internet provider availability

Building and property detail responses can include an internetProviders block sourced from official FCC Broadband Data Collection public data.
  • Coverage is exact-building when Borough has a matched FCC location and Census-block level when sourced from FCC public bulk files
  • Coverage is not unit-specific qualification
  • Data reflects likely providers, advertised technologies, and max download/upload speeds
  • Borough refreshes broadband availability on a monthly cadence and supports manual backfills for operational re-syncs
This product uses FCC APIs and/or Data but is not endorsed or certified by the FCC.
