Arguably the most important type of data set for residential real estate websites is the property actively being sold. Onboard Informatics offers an IDX API which makes available 3.5 million properties from 300+ MLS nationwide. Here is how our Listings API scores on the CRAAP test:
Currency - We pull data from each MLS via RETS every two hours (where available via the MLS’ capabilities). When a property is updated within the MLS whether price, status, pictures, etc… this information is pushed through our API and ensures it displays correctly on your website and within compliance.
Relevance - MLS data is the definitive source of residential real estate data being actively sold in the US. We combine the MLS data with the rest of our data platform to enable you to display hyper-local content which relates to the property.
Authority - Last November the National Association of Realtors (NAR) announced that they’d require all MLS to publish their IDX feeds in compliance with the Real Estate Standards Organization (RESO) format by June 2016. Onboard Informatics API is designed to implement this data dictionary.
Accuracy - Before publishing the IDX data into our API we process each record through an address standardization, correction, and geocoding process. Each property record is then tagged with all of our geographic boundaries; State, County, Place, Zip Code, Neighborhood, School District, and School Attendance Zone. This enables us to accurately return property based on any and all geographic searches requested by consumers.
Purpose - IDX data’s primary purpose is to be used in advertising residential real estate for sale. We retrieve, process, and host all of the content and media for property listings. We also standardize each separate MLS feed to provide consistent development effort and end user engagement. This enables our customers to focus on their unique consumer experience.
So there you have it, Onboard’s Listings API is 100% CRAAP. Try and implement this test next time you’re evaluating data.
