# API Reference

Working endpoint reference for the main PedAI flows. It covers the clinical, auth, Learning Hub, user data, and admin surfaces most commonly used by the frontend, but the source of truth is still `server.js` plus `src/routes/*.js`. Unless noted otherwise, authenticated endpoints require a valid web cookie or `Authorization: Bearer <token>` header.
