Botd vs UK Police

BotD is FingerprintJS's open-source, MIT-licensed JavaScript library that runs entirely in the browser to flag basic automation -- headless Chrome, PhantomJS, Selenium, and similar tools -- without any server round-trip for the detection itself. It ships as an npm package or as a CDN-hosted ES module and returns a plain detected/bot-kind result object from a single detect() call. It is free for any use with no signup; FingerprintJS separately sells a more sophisticated, paid, server-side Bot Detection API for teams that need those extra signals.

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.
