Coal - Payments for AI agents

Coal Coal gives AI agents a real checkout. Discover merchants through the decentralized 0G Storage catalog, pay autonomously in USDC on Base via x402 (Coinbase) or OKX APP (v2 envelope), and download purchased products — all without a human in the loop. Receipts are anchored on 0G Chain, allowing any third party to independently verify payments without trusting Coal itself. The MCP server is fully multi-tenant: every user supplies their own wallet key through the X-Coal-Agent-Key header, meaning the server never stores long-lived private keys or custody secrets. Agents are gasless by
