Create Account & API Key
Step 1: Sign Up
Go to app.chuizi.ai and click Sign Up. You can authenticate with:
- GitHub — recommended for developers
- Google — use your Google account
No email/password registration is required. OAuth handles authentication.
Step 2: Claim Free Credits
New accounts receive $0.50 in free credits automatically. This is enough for hundreds of requests with most models — plenty to test the gateway and verify your integration before adding funds.
You can check your balance at any time on the Billing page.
Step 3: Create an API Key
- Navigate to API Keys in the dashboard sidebar
- Click Create Key
- Enter a descriptive name (e.g., "dev-local", "cursor-editor", "production-backend")
- Click Create
Your new key is displayed once. Copy it immediately.
ck-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Warning: The full key is shown only at creation time. Chuizi.AI stores only a securely encrypted version of the key — the plaintext cannot be recovered. If you lose it, delete the key and create a new one.
Key Format
All Chuizi.AI API keys follow this format:
| Component | Value |
|---|---|
| Prefix | ck- |
| Body | 32 alphanumeric characters |
| Example | ck-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx |
The ck- prefix identifies the key as a Chuizi.AI key across all three protocols (OpenAI, Anthropic, Gemini).
Key Management
From the API Keys page you can:
- View active keys — see name, prefix (
ck-xxxx), creation date, and status - Delete a key — immediately revokes access; irreversible
- Set rate limits — configure per-key requests-per-minute (RPM)
- Restrict models — limit which models a key can access
- IP whitelist — restrict key usage to specific IP addresses
