+title: API Route Generator
+description: Template for creating Next.js API routes with proper error handling and validation
+---
+
+# API Route Template
+
+## Basic Structure
+```ts
+import { NextResponse } from "next/server"
+import { z } from "zod"
+
+// Input validation schema
+const inputSchema = z.object({
+  // Define input fields
+})
+
+// Response type
+type ApiResponse = {
+  data?: unknown
+  error?: string
+}
+
+export async function POST(req: Request) {
+  try {
+    // Parse and validate input
+    const body = await req.json()
+    const input = inputSchema.parse(body)
+
+    // Handle request
+    const result = await handleRequest(input)
+
+    // Return success response
+    return NextResponse.json({ data: result })
+
+  } catch (error) {
+    // Handle different error types
+    if (error instanceof z.ZodError) {
+      return NextResponse.json(
+        { error: "Invalid input" },
+        { status: 400 }
+      )
+    }
+
+    console.error("API Error:", error)
+    return NextResponse.json(
+      { error: "Internal server error" },
+      { status: 500 }
+    )
+  }
+}
+```
+
+## Best Practices
+- Always validate input with Zod
+- Use proper HTTP status codes
+- Implement rate limiting for public routes
+- Add proper error handling
+- Log errors appropriately
+- Add request validation middleware
+- Document API endpoints
+
+## Security Considerations
+- Validate authentication
+- Check authorization
+- Sanitize inputs
+- Handle sensitive data
+- Set proper CORS headers
+- Rate limit requests
+- Monitor for abuse
+
+## Testing
+- Add integration tests
+- Test error cases
+- Validate response formats
+- Check rate limiting
+- Test authentication
+- Verify authorization
+- Monitor performance
