### Description (declared)

Account-free crypto swaps between two addresses: no account, no sign-up, a floating rate, the network fee shown before sending. Over MCP and a REST API (OpenAPI): read-only tools for assets and routes, limits, quotes, address validation, swap status, payment links and signed status notifications, plus create_swap for an agent that controls the sending wallet and pays the payment instruction itself. For a person the swap is created on the page, from their own wallet. There is no A2A task endpoint.
