Free GPT API Key — Use GPT-5.5 Without a Credit Card

Call GPT-5.5, OpenAI's flagship model, for free. The keys are OpenAI-compatible, so your existing OpenAI code runs unchanged — you only swap the base URL. No OpenAI account, no sign-up, no card.

What you get

A working API key that reaches GPT-5.5 through an OpenAI-compatible gateway. Because it speaks the OpenAI API format, you keep your existing openai SDK code, prompts, and tooling — the only change is the base_url. Great for chat apps, agents, content generation, and drop-in replacement of paid OpenAI calls.

How sharing works: keys are public and pre-funded, so they may run out of budget, and capacity for any single model can fluctuate. If GPT-5.5 is busy, use Smart mode in the playground (it auto-routes to an available model) or pick another model from the table. For uninterrupted use, run a key inside your own app on your own quota.

FAQ

Is the GPT API key really free?

Yes. Keys are shared publicly with a pre-funded budget — no credit card, no sign-up. Because they're shared, a key may run out of budget; grab another from the table or come back later.

Which GPT model can I use?

GPT-5.5 via the model name gpt-5.5. Keys are OpenAI-compatible, so your existing OpenAI code works unchanged — you only change the base URL.

Do I need an OpenAI account?

No. Copy a key, set the base URL to https://aiapiv2.pekpik.com/v1, and call the API. No OpenAI account required.

What if GPT-5.5 is temporarily unavailable?

Capacity for a single model can fluctuate. Use Smart mode in the playground — it auto-routes to an available model — or pick Claude or DeepSeek from the table.
