Free ChatGPT API
Last updated:
A fully free ChatGPT API doesn't exist — the models cost money at the provider. But you can start without paying: new accounts get a test balance that covers hundreds of short requests.
What the free start includes
$0.25 balance
Credited automatically on sign-up. Enough for hundreds of short requests on light models.
No card
No bank card needed to start. Top up later with crypto.
Real models
The test balance runs on the full GPT-5.6 lineup, not a stripped demo.
How to start free
1. Sign up
With email or Google. The test balance appears on the account right away.
2. Generate a key
Create an API key in the dashboard and set our base URL in your SDK.
3. Send your first request
Use the familiar OpenAI format — usage is deducted from the test balance.
What happens when the bonus runs out
When the test balance is used up, the API stops until you top up. You top up with crypto and pay only for tokens used, at rates 50% below official. No auto-charges, no subscription.
