Turn your ChatGPT account into an OpenAI-compatible API key.
Sign in once, get a standard sk- key, and use it in any OpenAI-compatible tool — no separate API billing, no new integration to write.
curl https://api.bettergpt.dev/v1/chat/completions \

-H "Content-Type: application/json" \
-d '{

"messages": [{ "role": "user", "content": "Hello!" }]
}'Drop-in OpenAI compatible
Works anywhere an OPENAI_API_KEY and base URL do — the OpenAI SDK, LangChain, LiteLLM, Cursor, your own curl scripts.
Billed to your ChatGPT plan
No metered API billing. Requests run against the ChatGPT plan you already pay for — Free, Plus, or Pro.
Tokens encrypted at rest
Your ChatGPT credentials are encrypted before storage and never appear in a request you didn't make.
One key, full control
See when it was created and last used. Regenerate any time — the old key stops working immediately.
How it works
- 1
Sign in with ChatGPT
Authorize with your existing ChatGPT account — no new password, no credit card.
- 2
Get your API key
We mint a standard sk- key tied to your account. You'll see it exactly once, like any API key should be.
- 3
Use it anywhere
Point any OpenAI-compatible base URL at our gateway and pass your key. That's the whole integration.
