How It Works

AI agent calls a tool (e.g. spraay_batch_execute)
MCP server hits the Spraay x402 Gateway
Gateway returns 402 Payment Required with USDC amount
@x402/axios auto-signs a USDC micropayment from your wallet
Gateway validates payment and returns data
Agent gets the response

All payments are micro-transactions ($0.001–$0.05) in USDC on Base mainnet.

Requirements

Wallet: EVM private key with USDC on Base (even $1 covers thousands of calls)
Node.js: 18+
MCP Client: Claude Desktop, Cursor, or any MCP-compatible client
