How x402 Works

1. Your agent calls the endpoint with X402-Wallet header

2. Server verifies wallet has USDC on Arbitrum

3. Service executes and returns data

4. Payment settled on-chain (micro-transactions)

No API keys. No billing. No free tier limits. Just pay per call.

Wallet Setup

1. Get a wallet with USDC on Arbitrum

2. Use that wallet address in the X402-Wallet header

3. That's it — no signup needed
