Mozilla http scanner vs UK Police

The HTTP Observatory grades a website's security headers -- CSP, HSTS, cookie flags, and more -- against Mozilla's recommended baseline, the same engine behind the long-running Mozilla Observatory scanner. The original mozilla/http-observatory Python API was shut down on 2024-10-31 when the tool moved to MDN; automated callers now POST to a v2 scan endpoint that returns a grade, score, and pass/fail counts, with a details link back to the full MDN report. It's fully public and keyless, rate-limited to one fresh scan per host per minute (cached results are returned for repeat calls within that window), and built for CI-pipeline use.

The UK Police API publishes crime, stop-and-search, and neighbourhood-policing data reported by the 43 territorial forces of England and Wales, going back to December 2010 for street-level crime. It's a keyless JSON REST API -- force listings, neighbourhood team info, individual crime and outcome records, geo-radius crime queries -- released under the Open Government Licence, so results can be reused (including commercially) with attribution. Anonymous requests are capped at 15 per second with a burst of 30 before a 429 kicks in, comfortably enough for the dashboards and research tools that already build on it.
