EPA vs Food Standards Agency

EPA's Envirofacts platform exposes the agency's environmental compliance and monitoring databases — air quality, drinking water systems, the Toxics Release Inventory, hazardous waste, and Superfund sites — through a keyless REST API at `data.epa.gov/efservice`. Any of the underlying tables can be queried by building a URL from the table name, filter columns, and an output format, with results returned as JSON, XML, CSV, or Excel. EPA's Developer Central site separately documents smaller topic widgets built on the same data.

The Food Hygiene Rating Scheme API returns FHRS/FHIS inspection ratings for food businesses across the UK, filterable by local authority, name, and location. A live keyless query against `api.ratings.food.gov.uk/Establishments` (with the mandatory `x-api-version: 2` header) returned real establishment JSON with a wildcard `Access-Control-Allow-Origin` header. The stored `/open-data/en-GB` path now 404s after the host moved fully to HTTPS; the API itself needs no key, only the version header.
