Try Crime Data API without signup

Query the existing public MCP channel for a fixed Seattle location, then use a free key for REST queries.

Last updated: 2026-11-04

Fixed location: Pike Place Market, downtown Seattle (47.6097, -122.3422), within 500 metres. This live example uses the existing public MCP channel: last 180 days, at most 5 records, 60 tool calls per hour per IP.

Ready to query.

The response, including source metadata and newest record date, will appear here.

Empty results do not establish that no crime occurred. Review the source dates and licence in the response and city scope and freshness.

Use your own free key

Run these snippets locally. Key creation needs no email; keep the returned secret key server-side. Each query uses one request. Compare uses two points in Seattle.

curl (requires Python 3 to read the key)

export CRIME_API_KEY=$(curl --fail-with-body -sS -X POST 'https://crimedata.dev/v1/keys' | python3 -c 'import json,sys; print(json.load(sys.stdin)["api_key"])')
curl --fail-with-body -G 'https://crimedata.dev/v1/incidents' -H "x-api-key: $CRIME_API_KEY" --data-urlencode 'lat=47.6097' --data-urlencode 'lon=-122.3422' --data-urlencode 'radius_m=500' --data-urlencode 'limit=5'
curl --fail-with-body -G 'https://crimedata.dev/v1/stats' -H "x-api-key: $CRIME_API_KEY" --data-urlencode 'lat=47.6097' --data-urlencode 'lon=-122.3422' --data-urlencode 'radius_m=500'
curl --fail-with-body -G 'https://crimedata.dev/v1/compare' -H "x-api-key: $CRIME_API_KEY" --data-urlencode 'points=47.6097,-122.3422;47.6062,-122.3321' --data-urlencode 'radius_m=500'
