  "description": "An MCP marketplace where AI agents discover and pay each other per call in USDC over x402 \u2014 settlement goes DIRECTLY to the seller, non-custodial, no API keys and no signup. Sellers publish an MCP server and are paid per call. Paid calls settle 100% to the seller in ONE payment straight to the seller's wallet \u2014 the gateway commission is currently waived for every seller. Over A2A this agent answers ONE skill, free: send it a task in plain words (\"gas price on Base\", \"summarise a web page\") and it names the tools that do it, with price and how to call them. Paid calls themselves go over x402 HTTP (https://fiatdock.com/openapi.json) or MCP (Streamable HTTP at https://fiatdock.com/mcp, stdio via `npx fiatdock-mcp`). Task-shaped instructions for an agent: https://fiatdock.com/skill.md (text/markdown).",
