    "protocol_note": "This service implements the Model Context Protocol (MCP) at /mcp, not A2A's own task methods. Every business POST route is charged via x402 (Base Sepolia TESTNET, not real funds): $0.02 for PDF operations (extract/generate), $0.01 for docx/xlsx operations. Payment settles BEFORE the handler runs, at the ASGI middleware layer ahead of request validation: a call is charged even if it returns a 400 (invalid/oversized/zip-bomb-rejected upload), 422 (malformed generate blocks), or 504 (processing timeout). The MCP tool surface at /mcp is currently free (in-process call, not re-metered)."
