The numbers of the table as JSON. Every response carries the source and the caveats; please pass them on wherever you show the numbers. Machine-readable description: openapi.json.

Authentication and limits

• Send your key in the X-API-Key header. No key or an unknown key → 401. Request a key.
• 60 requests per minute per key → 429 with Retry-After beyond that.
• Slugs are case-insensitive; umlauts may be written as ae/oe/ue (ag-koeln).

GET /score

Parameters: court and/or airline (slugs from /courts and /airlines). With only court you get the court over all airlines, with only airline the airline over all courts. Neither → 400. An unknown slug → 404 with the closest valid slugs.
