Calling Claude Without KYC: The Order of Operations From Signup to First Response

Overview

This guide walks you through the exact sequence to call Claude models via a no-KYC API aggregator. You will top up with USDC on Base, create an API key, and send your first request using a model alias. Each step builds on the previous one, so following the order ensures a smooth start.

Step 1: Top Up with USDC on Base

Before you can make any API calls, you need a positive balance. The aggregator accepts USDC on the Base network, and no identity verification is required.

• Send USDC (on Base) to the deposit address provided in your dashboard.
• Wait for the transaction to confirm; your balance updates automatically.
• The amount you pay is the official model price multiplied by 1.3. This multiplier covers aggregation and infrastructure costs.

Note: If you are a key contributor (e.g., you referred users or contributed to the platform), you receive credits at official price × 1.1 (or × 1.2 for premium contributors) in USDC. This is separate from your top-up.

Step 2: Create an API Key

With a funded balance, generate an API key from the dashboard. This key authenticates every request and ties usage to your account.

• Navigate to the API keys section.
• Click “Create new key” and give it a descriptive name.
• Copy the key immediately; it will not be shown again.

Keep your key secure. Do not expose it in client-side code or public repositories.

Step 3: Choose a Model Alias

The aggregator uses aliases to route requests to different providers. For Claude, you will use an alias that maps to the underlying model. Check the documentation for the current list of aliases (e.g., claude-3-opus, claude-3-sonnet).

• Model aliases are stable identifiers; the actual model version may be updated behind the scenes.
• Using an alias ensures compatibility and avoids hardcoding provider-specific names.

Step 4: Make Your First API Call

Now you can send a request using curl. Replace YOURAPIKEY with the key from Step 2 and claude-3-sonnet with your chosen alias.

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

• The endpoint follows the OpenAI-compatible chat completions format.
• Adjust parameters like max_tokens or temperature as needed.
• The response includes the model’s reply and usage statistics.

Order Matters

Each step must precede the next: without a balance, you cannot create a key; without a key, you cannot authenticate; without a model alias, the request lacks a target. Following this sequence avoids common pitfalls and gets you from signup to first response quickly.

Troubleshooting

• Insufficient balance: Top up with more USDC on Base.
• Invalid API key: Ensure you copied the key correctly and did not revoke it.
• Model not found: Verify the alias against the documentation.
• Network issues: Confirm you are sending requests to the correct endpoint.

Conclusion

Calling Claude without KYC is straightforward when you follow the order: fund your account, create a key, pick an alias, and send a request. The aggregator handles provider routing, and you pay a transparent multiplier over official pricing. Start building today.
