Embeddable scorecard

Realtor and host widget demo

One tag, no dependencies: grade, score, top categories, 12-month trend and day/night split, in a shadow DOM that follows light and dark mode. It makes two API calls per render (/v1/score and /v1/stats) with a publishable widget key (pk_). Create it server-side with your secret key and an exact origin allowlist; calls share your secret key’s quota. Up to 10 widget keys per secret key; rotating the secret key revokes them all. Keep the secret key off your page. Incident density percentile, not a prediction of personal risk. How the score works.

<script src="https://crimedata.dev/embed.js" async></script>
<crime-scorecard lat="37.788" lon="-122.4075" radius="500" api-key="pk_YOUR_WIDGET_KEY"></crime-scorecard>

Attributes: lat and lon (or address), radius in metres (default 500), api-key. Keep the small attribution link in place.

curl -X POST 'https://crimedata.dev/v1/keys/widget' -H "x-api-key: $CRIME_API_KEY" -H 'content-type: application/json' --data '{"origins":["https://example.com"]}'
# Revoke with the parent secret:
curl -X DELETE 'https://crimedata.dev/v1/keys/widget/w_WIDGET_ID' -H "x-api-key: $CRIME_API_KEY"

Widget keys allow only GET /v1/score and /v1/stats with a matching Origin header. They cannot manage keys or read usage. Origin is a browser control only; non-browser clients can forge that header. Each widget has a daily cap (default up to 1,000 calls, configurable with daily_cap up to the parent’s remaining quota) and calls are also limited per IP.

Coverage

NYC publishes quarterly, so its newest records are about three months old. Cincinnati publishes lesser offenses only as "Part 2" with no detail, so they appear as other. Live freshness: GET /v1/cities.

Elsewhere in the US, /v1/score still answers with the city-wide FBI rates and national percentiles (coverage: "city_fallback"), not street-level incidents or a grade.
