  title: Nano RPC Accounts Keys API
  description: 'The Nano RPC API is a JSON-RPC HTTP interface for interacting with the Nano network. Nano is a feeless, instant digital currency using a block-lattice architecture where each account maintains its own blockchain. The RPC API supports account queries, block operations, wallet management, node diagnostics, and unit conversions. All requests are POST with a JSON body containing an "action" field identifying the RPC command.
