# `Layr8`
[🔗](https://github.com/layr8/elixir_sdk/blob/main/lib/layr8.ex#L1)

Elixir SDK for the Layr8 decentralized identity-native messaging network.

Layr8 enables agents to communicate over DIDComm v2 via a Phoenix Channel
WebSocket connection to a Layr8 cloud-node.

## Quick Start

    {:ok, client} = Layr8.Client.start_link(%{
      node_url: "wss://node.example.com/plugin_socket/websocket",
      api_key: System.fetch_env!("LAYR8_API_KEY")
    })

    Layr8.Client.handle(client, "https://example.com/echo/1.0/request", fn msg ->
      {:reply, %Layr8.Message{
        type: "https://example.com/echo/1.0/response",
        body: msg.body
      }}
    end)

    :ok = Layr8.Client.connect(client)
