xAI has published guidance for developers on how to debug errors when using its API. The documentation outlines typical error responses and provides solutions for common issues, including those related to the grok-4.6 model.

When an API request is sent, a successful response is typically indicated by a 200 OK status. However, if an error occurs, the API endpoint will return an error code along with a message.

Key Points

  • API endpoints typically return an error code and message if a request fails or a service error occurs.
  • Service disruption updates are available via the xAI status page at https://status.x.ai and an RSS feed at https://status.x.ai/feed.xml.
  • The service status is also displayed in the navigation bar of the xAI developer documentation site.
  • Most error messages are designed to be self-explanatory.
  • The 400 Bad Request status code can indicate issues such as an invalid argument in a POST request, insufficient API key permissions, a missing model, an invalid endpoint URL, or a missing Content-Type: application/json header.
  • For a 400 Bad Request due to a missing Content-Type header, the solution is to set the Content-Type: application/json header.

Context

According to xAI, developers can consult the API Reference for typical status codes associated with each endpoint. For ongoing service disruptions, xAI directs users to its status page or RSS feed. The company also encourages developers to report bugs by emailing support@x.ai with API request/response details and relevant logs, or by using the #help channel on the xAI API Developer Discord.

Why It Matters

Understanding common API error codes and their solutions can help developers efficiently diagnose and resolve issues when integrating with xAI's services, reducing development time and improving application reliability.

What To Do

  • Review the xAI API Reference for specific endpoint status codes.
  • Check https://status.x.ai or its RSS feed during suspected service disruptions.
  • Ensure Content-Type: application/json is set for POST requests to avoid 400 Bad Request errors.
  • Report suspected bugs to support@x.ai with request/response data and logs, or use the xAI API Developer Discord's #help channel.
