Cohere 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 (e.g., a required parameter was omitted, a charge failed, etc.).
  • Codes in the 5xx range indicate an error with Cohere’s servers (these are rare).

With a non-2xx response code, the response will be an error object in the following shape:

{
"message": string
}

Here are code examples for how error handling might look in our SDKs:

1 try:
2 response = co.generate(
3 model='invalid-model',
4 prompt='sample prompt')
5 except cohere.CohereError as e:
6 print(e.message)
7 print(e.http_status)
8 print(e.headers)
