Frequently asked questions
Redfin scores C+ on Supergood's API Report Card. No official public API. Redfin publishes no developer docs, issues no keys, and its terms disallow the internal endpoints that power the site; scraped access comes only from unsanctioned third parties. Free downloadable market-level CSVs are the sole sanctioned data channel.
Redfin has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Redfin is a technology-powered residential real estate brokerage and listings portal founded in 2004 in Seattle by David Eraker, Michael Dougherty, and David Selinger.
Real Estate -- specifically residential brokerage, listings aggregation, and consumer home search. Consumers use Redfin to search MLS listings on a map, save favorites, schedule in-person or video tours with Redfin agents, view Redfin Estimate valuations, submit offers, and (increasingly) get pre-approved for mortgages through Rocket.
9/10. Redfin reports ~50 million monthly unique visitors, making it the #2 or #3 U.S. real estate portal behind Zillow and roughly tied with Realtor.com.
For a buyer's-agent brokerage, a Redfin lead agent's most critical operating data lives behind login: active client roster with contact info, scheduled tour pipeline, saved-home activity per client, offer history, deal-stage notes, commission splits, transaction documents, and post-close client follow-up.
Founded 2004; IPO 2017 (NASDAQ: RDFN); acquired by Rocket Companies in 2025.
Agents are overworked / on-call 24/7, leading to poor client service. Low compensation; draw clawed back at closing, low commission splits. Full sourced list under Sources below.
Common alternatives include Zillow, Realtor.com, Compass, Homes.com, Trulia. Graded alternatives appear under "More from the report card" below.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Redfin has partial MCP support. Redfin does not offer an official MCP server. An actively maintained community server provides property search, listing details, and market data, and is listed in the official MCP registry.
Partially. MCP support for Redfin exists but is incomplete, so what MCP clients like Claude, Cursor, and Codex can reach depends on what the available server covers.
