InfraNode vs Nobel Prize

InfraNode unifies open data for dozens of German cities into a single versioned REST API, covering weather, air quality, EV charging, public-transit departures, demographics, and dozens of other civic datasets. Every endpoint is keyless and rate-limited per IP rather than gated behind a subscription ("Die API ist offen und braucht keinen API-Key"), with an OpenAPI spec and Postman collection published for quick integration. The project is open source (Apache-2.0) and runs on a server in Germany with no ads.

The official Nobel Prize API serves structured, keyless JSON on every laureate, prize category, and award year back to 1901, including prize amounts (nominal and inflation-adjusted) and links between related records. A live query against api.nobelprize.org/2.1/nobelPrizes needs no key and returns a wildcard Access-Control-Allow-Origin header, so it's directly callable from browser code.
