## Error Handling
|
||||
|
||||
All endpoints follow consistent error response format:
|
||||
|
||||
**Error Response:**
|
||||
```json
|
||||
{
|
||||
"error": "Error description",
|
||||
"code": "error_code",

}
|
||||
```
|
||||
|
||||
**Common HTTP Status Codes:**
|
||||
- `200`: Success
|
||||
- `400`: Bad request (validation error)
|
||||
- `404`: Resource not found
|
||||
- `409`: Conflict (e.g., batch job not ready)
|
||||
- `503`: Service unavailable (model loading)
|
||||
- `500`: Server error
|
||||
|
||||
## Rate Limiting
|
||||
|
||||
By default, the API enforces these limits:
|
||||
- **60 requests per minute** per client
|
||||
- **100 items maximum** per batch job
|
||||
- **10,000 characters maximum** per text
|
||||
- **4 concurrent requests** maximum
|
||||
|
||||
