CrimeScore rating is a propriety methodology based on address-level crime reports, weighted for type of crime, recency, and proximity, then adjusted by neighboring CrimeScore ratings, and finally statistically standardized across a bell curve based on all the CrimeScores across a city, updated daily.
CrimeScores are returned for the following cities, with more being added soon.

The CrimeScore API has been used in web apps, iOS apps, and a Pebble app.
