# ATProto

Implementation of the [ATProtocol](https://atproto.com/docs) client spec in Elixir.

## Installation

If [available in Hex](https://hex.pm/docs/publish), the package can be installed
by adding `atproto` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:atproto, "~> 0.1.0"}
  ]
end
```

The docs can be found at <https://hexdocs.pm/atproto>.

## Usage

`ATProtocol` uses [XRPC](https://github.com/moomerman/xrpc) for API communication, so we need to build an `XRPC.Client` and then we can call `ATProto` or `ATProto.BSky` functions.

Unauthenticated example:

```elixir
XRPC.Client.new("https://bsky.social")
|> ATProto.resolve_handle("atproto.com")

{:ok, %{"did" => "did:plc:ewvi7nxzyoun6zhxrhs64oiz"}}
```

Authenticated example:

```elixir
client = XRPC.Client.new("https://bsky.social")

{:ok, session} = ATProto.create_session(client, "atproto@example.com", "xxxx-xxxx-xxxx-xxxx")

client
|> Map.put(:access_token, session.access_jwt)
|> ATProto.BSky.get_profile("atproto.com")

{:ok,
 %ATProto.BSky.ProfileViewDetailed{
