# googly_cloud_vision

Google Cloud Vision API client library.

A modern, self-contained Elixir client for the Google Cloud Vision API, generated by
[googly](https://github.com/). Built on [Req](https://hex.pm/packages/req) and
[Jason](https://hex.pm/packages/jason).

## Installation

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

## Usage

Authentication is your concern — pass an OAuth2 bearer token (e.g. from
[Goth](https://hex.pm/packages/goth)) via the `:token` option:

```elixir
token = Goth.fetch!(MyApp.Goth).token

{:ok, result} = Googly.CloudVision.Operations.cancel(token: token)
```

Every call returns `{:ok, decoded}` on success. Failures are
`{:error, %Googly.CloudVision.Error{}}` for an error *response* (HTTP 4xx/5xx), or
`{:error, exception}` (e.g. `%Req.TransportError{}`) for transport-level failures.
