Pay per call with x402 / crypto wallet
How x402 works:
1. Send a GET request to any paid endpoint with header Accept: application/x402+json
2. You will get a 402 response with payment details and a signed challenge
3. Sign the challenge with your USDC wallet and send the transaction on Base network
4. Retry the request with the signed payment header

Quick start: 
npm install @goldbean/x402-sdk

curl -H "Accept: application/x402+json" \

2. Select a credit pack or membership plan
3. Choose payment method and click pay
4. Complete payment securely
5. Credits/membership are instantly activated

Credits: 1 credit = 1 call at $0.01 tier. Higher-tier endpoints cost more credits (e.g. LLM Chat = 8 credits/call).
Membership: Unlimited calls to all 47 endpoints for the duration of your plan.
