Error codes

Code	Cause	Solution
401 - Authentication Error	Missing or Invalid API Key	Ensure you are using the correct API Key and supplying it correctly
403 - Bad Request	Input token count + `max_tokens` parameter must be less than the context length of the model being queried.	Set `max_tokens` to a lower number. If querying a chat model, you may set `max_tokens` to `null` and let the model decide when to stop generation.
404 - Not Found	Invalid Endpoint URL or model name	Check your request is being made to the correct endpoint (see the API reference page for details) and that the model being queried is available
429 - Rate limit	Too many requests sent in a short period of time	Throttle the rate at which requests are sent to our servers (see our rate limits)
500 - Invalid Request	Misconfigured request	Ensure your request is a Valid JSON and your API Key is correct. Also ensure you're using the right prompt format - which is different for Mistral and LLaMA models.
