Example request and response

curl 'https://crimedata.dev/v1/incidents?lat=37.788&lon=-122.4075&radius_m=500&category=theft_from_vehicle&limit=2' \
  -H "x-api-key: $CRIME_API_KEY"

Illustrative response. The field names match /v1/incidents; the incident values are placeholders, not real records, and source is shortened.

Pass next_cursor back as cursor until it is null. Other endpoints: /v1/stats, /v1/compare, /v1/score, /v1/cities. Full reference: API docs. AI agents can use the free MCP server at https://crimedata.dev/mcp.

Coverage

Baltimore, Boston, Cincinnati, Dallas, Denver, Kansas City, Milwaukee, Minneapolis, New York City, San Francisco, Seattle and Washington DC. Each city comes from its own open-data portal, with its licence and newest record date shown on the coverage table and in GET /v1/cities. NYC publishes quarterly, so its records are about three months old. Elsewhere in the US, /v1/score returns city-wide FBI rates only, not street-level incidents.

Pricing

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. Compare with SpotCrime or the FBI API.
