Stream.Estate

Stream.Estate is a data API designed specifically for companies building real estate technology. It provides programmatic access to a massive database of over 50 million property listings in France, with plans to expand to more countries. The API delivers detailed information on properties, including location, size, amenities, and current status, along with market analytics like price-per-square-meter trends. It also supports real-time alerts via webhooks, so applications can be notified instantly when new properties are listed or prices change.

The service aggregates data from over 900 sources, processing more than 50,000 new property adverts every day to keep its database current. What makes Stream.Estate stand out is its focus on actionable data for developers. It offers advanced search and filtering capabilities, allowing users to query based on price, location, property type, and other specific criteria. The API is designed for easy integration, with clear documentation and code examples for languages like Python and Node.js.

This tool is a solid fit for PropTech startups, real estate agencies building custom tools, and financial institutions needing property valuation data. Practical use cases include building applications that spot undervalued properties listed below market price, generating instant property valuations based on real comparables, or identifying motivated sellers by tracking price drops and re-listings. It's essentially the data engine for anyone creating a smarter real estate platform.
