Centralized API for the KUHA program (sports and wellbeing data ecosystem). The service unifies data from multiple provider databases into a single access point.

• Program: KUHA (Kainuu Program for Sports and Well-being Data Analytics) in collaboration with CSC, University of Jyväskylä, KAMK, Finnish Olympic Committee, and others.
• Mission: Collect, integrate, and expose sports and wellbeing data through one API to enable data-driven coaching, research, and visualizations.
• Hosting: Provider databases are hosted in CSC infrastructure; this API brokers access and unifies schemas (“one API to rule them all”).

• Competition data (FIS results, rankings, events)
• Wearables and athlete monitoring (Garmin, Oura, Suunto, Polar via UTV)
• Training diaries and questionnaires (e.g., Tietoevry 360, KAMK forms)
• Performance testing (K-Lab, Coachtech/Vuokatti Sport test center)
• Motion analytics (Archinisis)
• Auth service for issuing access and refresh tokens

• cmd/api: HTTP server, routing, middleware, and handlers for each data domain/provider.
• cmd/migrate: SQL migrations and seeding entrypoint.
• internal: shared packages (DB connections, auth, caching, logging, rate limiting, stores).
• docs: Swagger definitions and generated artifacts.
