How to Get OpenAI API Key

Steps

1. Sign up or log in to the OpenAI platform: https://platform.openai.com/
2. Open the API Keys page (Manage → API keys).

3. Create a new secret key and copy it (the key is usually shown only once).

4. Secure storage and usage:

• Store the key in environment variables or a secure key management service; do not commit it to version control or include it in frontend code.
• Use it in server-side requests via the Authorization header: Authorization: Bearer YOUR_API_KEY (see official examples).

5. Management and rotation:

• Rotate keys regularly and revoke keys that are no longer used.
• If available, use fine-grained API keys and restrict permissions and allowed usage.
• Avoid exposing keys in client applications; use a backend proxy or controlled service to access the API.

Note — Billing and Quotas

• The OpenAI API is a paid service; configure billing in your account to avoid service interruptions.
• Review quotas and pricing; set budgets and alerts to prevent unexpected charges.
• For request formats, SDK examples, and best practices, see the official documentation: https://platform.openai.com/docs
