+## API Route Handlers
+
+Route handlers should validate inputs using Zod schemas.
+
+**Query parameters** (GET requests):
+
+```ts
+import { queryParamsSchemaValidationError, serviceErrorResponse } from "@/lib/serviceError";
+import { z } from "zod";
+
+const myQueryParamsSchema = z.object({
+    q: z.string().default(''),
+    page: z.coerce.number().int().positive().default(1),
+});
+
+export const GET = apiHandler(async (request: NextRequest) => {
+    const rawParams = Object.fromEntries(
+        Object.keys(myQueryParamsSchema.shape).map(key => [
+            key,
+            request.nextUrl.searchParams.get(key) ?? undefined
+        ])
+    );
+    const parsed = myQueryParamsSchema.safeParse(rawParams);
+
+    if (!parsed.success) {
+        return serviceErrorResponse(
+            queryParamsSchemaValidationError(parsed.error)
+        );
+    }
+
+    const { q, page } = parsed.data;
+    // ... rest of handler
+});
+```
+
+**Request body** (POST/PUT/PATCH requests):
+
+```ts
+import { requestBodySchemaValidationError, serviceErrorResponse } from "@/lib/serviceError";
+import { z } from "zod";
+
+const myRequestBodySchema = z.object({
+    name: z.string(),
+    count: z.number().optional(),
+});
+
+export const POST = apiHandler(async (request: NextRequest) => {
+    const body = await request.json();
+    const parsed = myRequestBodySchema.safeParse(body);
+
+    if (!parsed.success) {
+        return serviceErrorResponse(
+            requestBodySchemaValidationError(parsed.error)
+        );
+    }
+
+    const { name, count } = parsed.data;
+    // ... rest of handler
+});
+```
+
+## Data Fetching
+
+For GET requests, prefer using API routes with react-query over server actions. This provides caching benefits and better control over data refetching.
+
+```tsx
+// Preferred: API route + react-query
+import { useQuery } from "@tanstack/react-query";
+
+const { data, isLoading } = useQuery({
+    queryKey: ["items", id],
+    queryFn: () => fetch(`/api/items/${id}`).then(res => res.json()),
+});
+```
+
+Server actions should be used for mutations (POST/PUT/DELETE operations), not for data fetching.
+
+## Authentication
+
+Use `withAuthV2` or `withOptionalAuthV2` from `@/withAuthV2` to protect server actions and API routes.
+
+- **`withAuthV2`** - Requires authentication. Returns `notAuthenticated()` if user is not logged in.
+- **`withOptionalAuthV2`** - Allows anonymous access if the org has anonymous access enabled. `user` may be `undefined`.
+- **`withMinimumOrgRole`** - Wrap inside auth context to require a minimum role (e.g., `OrgRole.OWNER`).
+
+**Important:** Always use the `prisma` instance provided by the auth context. This instance has `userScopedPrismaClientExtension` applied, which enforces repository visibility rules (e.g., filtering repos based on user permissions). Do NOT import `prisma` directly from `@/prisma` in actions or routes that return data to the client.
+
+**Server actions** - Wrap with `sew()` for error handling:
+
+```ts
+'use server';
+
+import { sew } from "@/actions";
+import { withAuthV2 } from "@/withAuthV2";
+
+export const myProtectedAction = async ({ id }: { id: string }) => sew(() =>
+    withAuthV2(async ({ org, user, prisma }) => {
+        // user is guaranteed to be defined
+        // prisma is scoped to the user
+        return { success: true };
+    })
+);
+
+export const myPublicAction = async ({ id }: { id: string }) => sew(() =>
+    withOptionalAuthV2(async ({ org, user, prisma }) => {
+        // user may be undefined for anonymous access
+        return { success: true };
+    })
+);
+```
+
+**API routes** - Check `isServiceError` and return `serviceErrorResponse`:
+
+```ts
+import { serviceErrorResponse } from "@/lib/serviceError";
+import { isServiceError } from "@/lib/utils";
+import { withAuthV2 } from "@/withAuthV2";
+
+export const GET = apiHandler(async (request: NextRequest) => {
+    const result = await withAuthV2(async ({ org, user, prisma }) => {
+        // ... your logic
+        return data;
+    });
+
+    if (isServiceError(result)) {
+        return serviceErrorResponse(result);
+    }
+
+    return Response.json(result);
+});
+```
