How Payment Works
Each endpoint returns HTTP 402 with an x402 payment challenge. The agent pays USDC on Base chain (~.01 to .10 per call) and retries. No API key needed — just a USDC wallet.

Architecture
AI Agent (Claude, Cursor, etc.) → MCP Client → GoldBean MCP Server → goldbean-api.xyz → x402 Payment → Response
The MCP server acts as a bridge: agents call standard MCP tools, the server handles x402 payment challenges, and returns real data.
