What you can show

• Counts of police-reported incidents within a radius of a listing, by category and month (/v1/stats).
• Recent incidents on a map (/v1/incidents) with the city source and licence shown.
• Address in, result out: pass address instead of lat and lon.

Coverage

Baltimore, Boston, Cincinnati, Dallas, Kansas City, Milwaukee, Minneapolis, New York City, San Francisco, Seattle and Washington DC. Elsewhere in the US, /v1/score returns city-wide FBI rates only, not street-level incidents. Check coverage with GET /v1/cities before you show anything for a listing.

How to present it

Label it "police-reported incidents nearby", show the date window and the source attribution, and do not rank or label neighborhoods "safe" or "unsafe" from it. Reports reflect where and how incidents are reported, not who lives there.

Not for screening

Real estate apps often sit near tenant screening. This API must not be used to decide whether to rent to, sell to or approve a person. Use it only as area context about places.

Limits

Crime Data API is not a consumer reporting agency. Do not use it for tenant, employment, credit or insurance screening or any eligibility decision. Reported incidents are not convictions or a prediction of personal risk. Data is revised by the source and can be incomplete; keep the source attribution and check each city's licence for your use.

FAQ

Can I show crime data on property listings?

Display factual incident counts using consistent geography and date windows. Do not use this service to rank housing opportunities, label neighborhoods safe or unsafe, or steer people based on protected characteristics or proxies. Availability of data is not legal approval of a particular housing use. Check the licence of each city and that the city is covered.

Do not use this data to steer buyers or renters toward or away from areas, or to describe neighbourhoods by the race, religion, national origin, sex, disability or family status of the people who live there.
