<h3>Troubleshooting</h3>
<h3>“Missing API Key” Error</h3>
<p>Solution: Ensure you have:</p>
<p>Generated an API key from your chosen AI provider</p>
<p>Entered it in the plugin settings</p>
<p>Saved the settings</p>
<h3>“API returned HTTP 429” (Rate Limited)</h3>
<p>Solution:</p>
<p>The AI provider is rate-limiting your requests</p>
<p>The plugin will automatically retry with exponential backoff</p>
<p>If it persists, try switching AI providers or wait a few minutes</p>
<p>Consider upgrading your API plan with the provider</p>
<h3>“Model not found” Error</h3>
<p>Solution:</p>
<p>The model name may be deprecated</p>
<p>The plugin auto-updates deprecated models to current versions</p>
<p>Try switching between Groq and Gemini to find a working option</p>
<h3>“Invalid JSON Response” Error</h3>
<p>Solution:</p>
<p>The AI model returned unexpected format</p>
<p>This is usually temporary – try again</p>
<p>If persistent, check your API key validity</p>
<p>Consider using a different AI provider</p>
<h3>API Response Examples</h3>
<h3>Success Response</h3>
<p>{<br />
  “jsonrpc”: “2.0”,<br />
  “id”: 1,<br />
  “result”: {<br />

    “code”: -32600,<br />
    “message”: “Coupon code is required.”<br />
  }<br />
}</p>
<h3>Security</h3>

<p>HTTPS is recommended for all API calls</p>
<h3>Performance Tips</h3>

<p>Monitor rate limits and adjust request frequency</p>
