# Support

> Troubleshoot failed requests, billing questions, and integration problems before contacting support.

Start with the usage logs. They are the fastest way to understand failed requests, quota problems, model permission issues, and unexpected costs.

<Steps>
  <Step title="Check usage logs">
    Confirm the request reached Moxus AI and review the error message.
  </Step>

  <Step title="Verify API key settings">
    Check whether the key is enabled, expired, quota-limited, IP-limited, or model-limited.
  </Step>

  <Step title="Confirm the model name">
    Copy the model name from the model catalog instead of typing it manually.
  </Step>

  <Step title="Test with cURL">
    Reproduce the issue with a minimal request to separate client issues from API issues.
  </Step>
</Steps>
