HTTP Error Codes

The following error codes are returned as part of a standard HTTP response.

HTTP Error Code	Description	Troubleshooting
400	Bad Request	This error most often occurs when there is something syntactically incorrect in the body of your request. Check your request format and try again. For example, this error could occur if the request body size is greater than 500 KB, or if the number of items to scan in the payload exceeds 50,000.
401	Unauthorized	You may be using an incorrect API key or calling the wrong endpoint.
422	Unprocessable Entity	You may be using an invalid or unrecognized detector set. You may also have exceeded the maximum allowable payload size; try spreading your payload across multiple requests.
429	Too Many Requests or Quota Exceeded	Either your monthly request limit has been exceeded, or you have exceeded the allowed rate limit. Consider upgrading to a higher volume plan, or wait several moments to retry the requests.
500	Internal Server Error	Wait a few moments and try again. If the problem persists, Nightfall may be experiencing an outage.
