Installation

x402 Payment Setup (Required for Real Payments)
To enable real USDC payments on Base:
- Create a wallet on Base mainnet
- Set environment variable:
export X402_RECIPIENT_ADDRESS="0xYourWalletAddress" - (Optional) Use testnet:
export X402_NETWORK="base-sepolia" # Default: base-mainnet
Without X402_RECIPIENT_ADDRESS, the server runs in placeholder mode (accepts any payment token).

How x402 Payments Work

402 Payment Required - Client constructs x402 payment via Coinbase CDP SDK
- Client calls tool with
_payment_tokenparameter - Server verifies payment via Coinbase facilitator
- Tool executes and returns result
