Orquesta uses conventional HTTP 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 Orquesta or the LLM provider servers.

The id of the transaction is useful for reporting metrics in the logs. If the transaction code is 4xx, any attempts to report metrics will result in an error.

For specific errors that can be handled programmatically, an error code is provided. Refer to the table below for a summary of these codes.

error message
