Get an OpenAI API Key
ChatGPT chat login is not enough—keys live on OpenAI Platform.
Steps
- Sign in at platform.openai.com.
- Open API keys → Create new secret key → copy and store it (shown once).
- Under Billing, add a payment method and confirm quota. Wrong org/project permissions also cause 401/403.
- WriteX → Settings → Model / Provider → OpenAI → paste key → pick a model → Test & save.
Network note
Some networks can’t reach OpenAI. Use a company gateway or another OpenAI-compatible endpoint if needed.
