Redfin Data Center vs Repliers API for AI agents
Redfin's Data Center offers downloadable US housing market statistics; Redfin publishes no listings API. Repliers API is a real estate data API that connects to US and Canadian MLSs and serves their listings through one REST API, with AI search features and an official MCP server.
The short answer
- Redfin Data Center: Free-to-download market trend data (prices, inventory, delistings) for research and charts, not finding a specific home.
- Repliers API: Licensed agents and brokerages who want an AI-ready, MCP-connected API on top of their own MLS feed.
Side by side
| Redfin Data Center | Repliers API | |
|---|---|---|
| Searches | Market-level series such as the Housing Market Tracker (weekly and monthly), Redfin Home Price Index, price drops, delistings and investor purchases; not individual homes. | MLS listings from the boards you are licensed with (500+ boards listed), with sold data where your MLS agreement allows. |
| Returns | Download files where each row is one region for one time period. | Listing records including an agents field with contact information, brokerage affiliation and roles, plus office details. |
| Before the first call | Nothing stated; the data is a download button on the page. | A Repliers account and API key; production data requires being a licensed real estate agent with a data agreement with your MLS. |
| Free | – | Preview plan: $0 a month, with sample data only. |
| Paid | – | Standard plan: $199 a month (single MLS). |
| Acting on a result | Nothing: the downloads are aggregate statistics with no listings or contacts. | Listings include the listing agents' contact details (email, phones, website) and brokerage, as the MLS provides them. |
| Limits on keeping or showing results | Redfin's terms forbid automated crawling or querying of the site and copying or redistributing MLS listing information. | Not stated on its pages |
| AI in its terms | No AI rule; the only AI mention is an MLS (BAREIS) disclaimer that listing material may have been generated by AI. | Not stated on its pages |
| Coverage | US | US and Canada, MLS by MLS (500+ boards listed). |
| MCP server | – | Official open-source MCP server, hosted at https://mcp.repliers.io (repo: https://github.com/Repliers-io/mcp-server) |
