Homes.com is a United States residential real estate portal owned by CoStar Group, which acquired the property in 2021 and folded the Homesnap agent application into it — homesnap.com now issues an HTTP 301 to www.homes.com. It sits on the consumer-facing portal layer of the US housing value chain, alongside Zillow, Realtor.com, and Redfin: it aggregates for-sale, for-rent, and off-market listings sourced from Multiple Listing Services and broker syndication, and monetises through an agent-first "your listing, your lead" advertising and agent-directory product rather than through data distribution. Its API posture is empty in both directions of the RESO question. Homes.com appears in the RESO organization directory as an active Technology Company (OrganizationUniqueId T00000143), but the Data Dictionary and Web API certification columns for that row are blank — it holds no RESO certification of any version, unlike rival Move/Realtor.com (Data Dictionary 1.7 Passed, Web API Core 2.0.0 Passed) or Zillow's Bridge Interactive (Data Dictionary 1.7 and Web API Core 2.0.0, Certified Legacy). Separately, no developer surface is published at all: developer., developers., api., docs., apis., dev., idx., feeds., and data. subdomains of homes.com do not resolve in DNS, and every path on www.homes.com returns HTTP 403 to non-browser clients behind Akamai bot protection. Listing data moves INTO Homes.com from MLSs and brokers via syndication opt-in, not OUT through any documented API. No OpenAPI, no OData $metadata, no webhooks, no SDK, no Postman collection, and no published authentication scheme were found. The GitHub organizations Homesnap and CoStarGroup contain only archived forks of third-party libraries — including libRETS, which is evidence of consuming MLS feeds rather than publishing them. Third-party "Homes.com APIs" on RapidAPI, Apify, Parse, and RealtyAPI are unofficial scrapers and are not recorded here as provider APIs.
