## Overview

Fast API responses improve overall application performance and user experience. Optimization focuses on payload size, caching, and query efficiency.

## When to Use

- Slow API response times
- High server CPU/memory usage
- Large response payloads
- Performance degradation
- Scaling bottlenecks

## Quick Start

Minimal working example:

```javascript
// Inefficient response (unnecessary data)
GET /api/users/123
{
  "id": 123,
  "name": "John",
  "email": "john@example.com",
  "password_hash": "...", // ❌ Should never send
  "ssn": "123-45-6789", // ❌ Sensitive data
  "internal_id": "xyz",
  "created_at": "2024-01-01T00:00:00Z",
  "updated_at": "2024-01-02T00:00:00Z",
  "meta_data": {...}, // ❌ Unused fields
  "address": {
    "street": "123 Main",
    "city": "City",
    "state": "ST",
    "zip": "12345",
    "geo": {...} // ❌ Not needed
  }
}

// Optimized response (only needed fields)
GET /api/users/123
{
  "id": 123,
// ... (see reference guides for full implementation)
```

## Best Practices

### ✅ DO

- Follow established patterns and conventions
- Write clean, maintainable code
- Add appropriate documentation
- Test thoroughly before deploying

### ❌ DON'T

- Skip testing or validation
- Ignore error handling
- Hard-code configuration values
