The Accuracy score on Redfin search APIs
This score, out of 100, shows how many homes and home details a provider returns for a search.
- The score also shows whether those details match Redfin's.
- We send each provider the same US ZIP codes a person types into Redfin's search box.
- Some providers' calls take Redfin's ID for a ZIP code in place of the ZIP code.
- We send those providers the ID.
- Within minutes of each call, we read Redfin's search results for the same ZIP code.
- We compare each provider's answer with Redfin's page at the time we called that provider.
- We score each search on parts: the number of homes, and each home detail such as the price.
- We count a part on a search only when Redfin's page shows the part on every day we called providers.
- For homes, we count the provider's homes that are also on Redfin's page.
- We divide that count by the number of homes on Redfin's page.
- For each home detail, we look only at homes where Redfin shows that detail.
- We then take the share of those homes where the provider lists the detail.
- We count a price, bedroom count, bathroom count or living area as missing when the value differs from Redfin's.
- On each search, we average the provider's shares over the parts that count on that search.
- Then we average over all searches.
- Each search has the same weight.
- A provider scores 0 on a search where the provider's call returned no homes.
- We compare a provider that ran on fewer searches with the other providers on those same searches.
- A provider can't score higher by running only on easy searches.
- We lower the score when we test the call on fewer searches than the benchmark has.
