How to Use OpenAI API Key in DapperGPT

If you want full control over cost and model choice, use your own OpenAI key.

Step 1: Create an OpenAI API key

• Go to the OpenAI platform dashboard.
• Open API keys.
• Create a new secret key.
• Copy it once and store it safely.

Step 2: Add your key in DapperGPT

• Open DapperGPT settings.
• Choose OpenAI as provider.
• Paste your key.
• Save and select a model.

Step 3: Start with a quick validation prompt

Use a simple prompt first:

Reply with "OpenAI connection works" and include today's date.

If it answers correctly, your setup is complete.

Best practices

• Never share your API key publicly.
• Rotate keys if exposed.
• Set budget or usage alerts in your provider dashboard.
• Use project-specific keys when possible.

Troubleshooting

• 401 unauthorized: key is invalid or revoked.
• 429 rate limit: reduce request rate or check quota.
• Model not found: pick a model available to your account.
