## Common Errors

### 401 Unauthorized

**Cause:** Missing or invalid API key

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{"detail": "Invalid API key for organization", "code": "INVALID_API_KEY"}
```

### 403 Forbidden

**Cause:** The authenticated user is not a member of the organization

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{"detail": "Logged User is not Member of Organization", "code": "LOGGED_USER_NOT_MEMBER"}
```

### 422 Validation Error

**Cause:** Check-out date is before check-in date (when both are provided)

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": [
    {
      "loc": ["body", "check_out_date"],
      "msg": "check_out_date must be on or after check_in_date",
      "type": "value_error"
    }
  ]
}
```
