+# Frontend API Guide (HotTRDeals)
+
+This file is a frontend-focused summary of current backend routes, auth, and response models.
+Server entry: `server.js`.
+
+## Base URL and CORS
+- Local API base: `http://localhost:3000`
+- All routes below are relative to `/api`.
+- CORS in dev allows `http://localhost:5173` and `credentials: true`.
+
+## Auth summary
+- Access token is returned in response body: `{ token, user }`.
+- Send access token via header: `Authorization: Bearer <token>`.
+- Refresh token is stored in httpOnly cookie named `rt`.
+- For `/auth/refresh` and `/auth/logout`, the frontend must send cookies (`withCredentials: true`).
+- Cookie options:
+  - Dev: `secure=false`, `sameSite=lax`
+  - Prod: `secure=true`, `sameSite=none`
+
+## Roles
+- Roles: `USER`, `MOD`, `ADMIN`.
+- `requireRole("MOD")` means only MOD and ADMIN can access.
+
+## Common response shapes
+- Errors are inconsistent:
+  - Some endpoints return `{ error: "..." }`
+  - Some endpoints return `{ message: "..." }`
+- Expect both in frontend error handling.
+
+## Common models (from adapters/contracts)
+
+### PublicUserSummary
+```
+{
+  id: number,
+  username: string,
+  avatarUrl: string | null
+}
+```
+
+### PublicUserDetails
+```
+{
+  id: number,
+  username: string,
+  avatarUrl: string | null,
+  email: string,
+  createdAt: string (ISO)
+}
+```
+
+### AuthUser
+```
+{
+  id: number,
+  username: string,
+  email: string,
+  role: "USER" | "MOD" | "ADMIN",
+  avatarUrl: string | null
+}
+```
+
+### DealCard
+```
+{
+  id: number,
+  title: string,
+  description: string,
+  price: number | null,
+  originalPrice?: number | null,
+  shippingPrice?: number | null,

+## Notes for frontend
+- Some list endpoints return full pagination object, some return only `results` array. Treat them separately:
+  - Full: `/api/deals` list endpoints, `/api/deals/search`, `/api/deals/users/:userName/deals`, `/api/deals/me/deals`
+  - Array only: `/api/deals/top`, `/api/category/:slug/deals`, `/api/seller/:sellerName/deals`, `/api/mod/deals/pending`
+- Optional-auth endpoints return `401` if a token is provided but invalid.
+- MyVote is only filled when Authorization header is present.
+- There are duplicate route prefixes for users and votes. Frontend can use either, but pick one for consistency.
