# `OpenrouterSdk.Config`
[🔗](https://github.com/zmzlois/openrouter_sdk/blob/v0.1.0/lib/openrouter_sdk/config.ex#L1)

immutable configuration for the sdk.

built once via `new/1`, then merged with per-call opts inside each
api function. anything you'd ever want to override on a single
request — api key, headers, middleware — lives here.

# `t`

```elixir
@type t() :: %OpenrouterSdk.Config{
  api_key: String.t() | nil,
  base_url: String.t(),
  default_headers: [{String.t(), String.t()}],
  finch_name: atom(),
  middleware: [module() | {module(), keyword()}],
  pool_timeout: pos_integer(),
  receive_timeout: pos_integer(),
  request_timeout: pos_integer(),
  telemetry_metadata: map()
}
```

# `merge`

```elixir
@spec merge(
  t(),
  keyword()
) :: t()
```

merge a keyword override into an existing config (used per-call)

# `new`

```elixir
@spec new(keyword()) :: t()
```

build a config. opts override application env, application env
overrides defaults.
