No-KYC LLM API: From USDC Payment to First Successful Call in 10 Minutes

Why a No-KYC API Aggregator?

Traditional LLM API providers often require account verification, which can delay access. This aggregator removes that friction: you create an API key, top up with USDC on Base, and immediately call multiple models (Claude, GPT, DeepSeek, Qwen, GLM, Kimi) using a single API key. Pricing is transparent: you pay official price × 1.3, and contributors earn back official price × 1.1 (premium × 1.2) in USDC.

Step 1: Create Your API Key

1. Visit the aggregator's website.
2. Sign up with an email or wallet address. No KYC is required.
3. Navigate to the API keys section and generate a new key.
4. Copy the key and store it securely. You'll use it for all requests.

Step 2: Top Up with USDC on Base

1. Go to the billing or top-up page.
2. Select USDC on Base as your payment method.
3. Send USDC to the provided address. The amount will be credited to your account balance.
4. Wait for the transaction to confirm (usually within seconds on Base).

Step 3: Send Your First API Request

Use a simple curl command to test your key. Replace YOURAPIKEY with your actual key.

curl https://api.example.com/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-3-opus-20240229",
    "messages": [{"role": "user", "content": "Hello, world!"}]
  }'

If successful, you'll receive a JSON response with the model's reply. You can switch models by changing the model parameter (e.g., gpt-4, deepseek-chat).

Step 4: Monitor Usage and Costs

Your account dashboard shows usage and remaining balance. Charges are calculated as official price × 1.3, deducted from your USDC balance. No hidden fees.

Step 5: Contribute and Earn (Optional)

If you provide API keys from supported providers, you can earn USDC credits. For each call made through your key, you receive official price × 1.1 (or × 1.2 for premium models) in USDC. This makes it a self-sustaining ecosystem.

Troubleshooting Tips

• Invalid API key: Ensure the key is copied correctly and not expired.
• Insufficient balance: Top up with USDC on Base.
• Model not found: Check the available model list in the docs.
• Network issues: Base transactions are fast, but allow a few seconds for confirmation.

Conclusion

With no KYC and instant USDC top-ups, you can start calling Claude, GPT, and other models in minutes. The transparent pricing (×1.3 for users, ×1.1/×1.2 back for contributors) keeps costs predictable and rewards participation.
