API reference
The InfraNode API serves open data for 84 major German cities through 116 endpoints, grouped by topic. Every endpoint has its own page with parameters, ready-to-run examples for curl, JavaScript and Python, and a try-it console.
All endpoints are key-free and read-only. Responses always
follow the same envelope of data and meta; a
missing upstream yields an honest source_status rather than an
error. The machine-readable specification lives at
/api/v1/openapi.yaml.
