isEven (humor) vs USGS Earthquake Hazards Program
isEven is a parody of the infamous is-even npm-package controversy, wrapped as a keyless REST endpoint that answers whether a given number is even. The free tier's JSON response bundles in a joke classified ad alongside the boolean result; a paid Premium/Enterprise tier removes the ads.
The USGS Earthquake Hazards Program's FDSNWS Event Web Service is a keyless REST API for querying the agency's global earthquake catalog by region, time window, magnitude, or depth, returning real-time and historical seismic event data. Requests default to QuakeML XML but can also return GeoJSON, CSV, or KML via a format parameter, and the whole service is free and unauthenticated, run directly by the federal government.
