# 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 default — Coal covers operator gas costs. --- ## MCP Tools (13) ### Discovery & Marketplace * `discover_merchants` Browse the marketplace as a Markdown product grid * `search_products` Search and filter by product name, price, or tags * `get_merchant_profile` Retrieve merchant metadata and payout addresses * `query_merchant_memory` Natural-language merchant Q&A powered by TEE-backed 0G Compute --- ### Payments & Checkout * `check_paywall` Check whether an address has already paid * `create_checkout` Create a Coal checkout session *(requires API key)* * `get_checkout_status` Retrieve checkout session state and payment status * `pay_merchant` Send USDC on Base using ERC-3009 gasless transfers --- ### Verification & Delivery * `verify_receipt` Verify the complete proof trail: 1.
