# Errors

Portkey uses conventional response codes to indicate the success or failure of an API request. In general: Codes in the `2xx` range indicate success. Codes in the `4xx` range indicate an error that failed given the information provided. Codes in the `5xx` range indicate an error with Portkey’s servers (these are rare).

## Common Errors

During request processing, you may encounter error codes from either Portkey or the LLM provider:

| Status Code | Description                                  | Source              |
| ----------- | -------------------------------------------- | ------------------- |
| `408`       | Request timed out                            | Portkey OR Provider |
| `412`       | Budget exhausted                             | Portkey OR Provider |
| `429`       | Request rate limited                         | Portkey OR Provider |
| `446`       | Guardrail checks failed (request denied)     | Portkey             |
| `246`       | Guardrail checks failed (request successful) | Portkey             |
