## 개요

**Base URL**: `http://localhost:8101/api/v1`

**Content-Type**: `application/json`

**인증 방식**: JWT Bearer Token (OAuth2 Password Flow)

**테스트 완료**: 37개 엔드포인트 모두 테스트 완료 (100% 성공률)

---

## 인증

### OAuth2 Password Flow

모든 API 요청은 JWT 토큰을 통한 인증이 필요합니다.

#### 로그인하여 토큰 받기

```bash
POST /api/v1/users/login
Content-Type: application/x-www-form-urlencoded

username=admin&password=admin123456
```

**응답:**
```json
{
  "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
  "token_type": "bearer",
  "expires_in": 1800
}
```

#### 인증된 요청 보내기

모든 API 요청에 Authorization 헤더를 포함해야 합니다:

```bash
Authorization: Bearer {access_token}
```

## 에러 코드

### HTTP 상태 코드

| 코드 | 의미 | 설명 |
|------|------|------|
| 200 | OK | 요청 성공 |
| 201 | Created | 리소스 생성 성공 |
| 204 | No Content | 요청 성공, 응답 본문 없음 (주로 DELETE) |
| 400 | Bad Request | 잘못된 요청 (유효성 검증 실패) |
| 401 | Unauthorized | 인증 실패 (토큰 없음/만료/잘못됨) |
| 403 | Forbidden | 권한 없음 (인증은 되었으나 권한 부족) |
| 404 | Not Found | 리소스를 찾을 수 없음 |
| 500 | Internal Server Error | 서버 내부 오류 |

### 에러 응답 형식

모든 에러는 다음 형식으로 반환됩니다:

```json
{
  "detail": "Error message describing what went wrong"
}
```

### 일반적인 에러 예제

#### 1. 인증 실패 (401)
```json
{
  "detail": "Incorrect username or password"
}
```

#### 2. 권한 부족 (403)
```json
{
  "detail": "Only admins can list users"
}
```

#### 3. 리소스 없음 (404)
```json
{
  "detail": "User with ID 507f1f77bcf86cd799439011 not found"
}
```

#### 4. 유효성 검증 실패 (400)
```json
{
  "detail": "Username already exists"
}
```

#### 5. 토큰 만료 (401)
```json
{
  "detail": "Could not validate credentials"
}
```
