Cursor lets you bring your own OpenAI-compatible endpoint. Point it at a free shared key and use Claude Opus, GPT-5.5, DeepSeek and more — no Cursor subscription, no credit card.
https://aiapiv2.pekpik.com/v1.claude-opus-4-7 (or gpt-5.5, deepseek-chat) and save.claude-opus-4-7 is a strong
default for editing and refactoring. If a model is busy or a key runs out, switch
to another model or paste a fresh key — keys rotate throughout the day.
Before wiring it into Cursor, you can sanity-check a key in seconds:
curl https://aiapiv2.pekpik.com/v1/chat/completions \
-H "Authorization: Bearer YOUR_FREE_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"claude-opus-4-7","messages":[{"role":"user","content":"hi"}]}'Or use the playground Verify tab to test a key in your browser.
Yes. Cursor supports a custom OpenAI base URL and key. Point it at the FreeLLMShare gateway with a free key to use Claude, GPT-5.5 and more without a subscription or credit card.
For coding, claude-opus-4-7 is excellent. You can also use gpt-5.5 or deepseek-chat. If one is busy, switch to another from the table.
Set the OpenAI Base URL to https://aiapiv2.pekpik.com/v1 and paste a free key.
Shared keys can run out of budget. Replace it in Cursor settings with another from the table. For uninterrupted use, run your own key on your own quota.
