Open Data — entry 013 of 44
InfraNode
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.
