SimplyRETS
Developer API that turns MLS feeds into a clean JSON REST API.
About SimplyRETS
SimplyRETS is a developer platform that normalizes RETS and RESO Web API MLS feeds into a standardized RESTful JSON API for building real estate websites and applications. It provides a listings search API with geographic queries, plus endpoints for open houses, agent information, and market analytics such as average prices and days on market, along with a WordPress plugin for IDX-style sites. Property coverage spans residential, condos, rentals, multifamily, commercial, and farm/lot/land listings depending on the connected MLS feed. Pricing is published, starting at $49 per month with a one-time $99 connection fee per feed, and demo API credentials are available for testing before connecting live MLS data.
