Cross-Platform

Kotlin Multiplatform

You can use Gateway to route your API calls without changing your current SDK.

OpenAI API client for Kotlin

com.aallam.openai:openai-client

Follow the official documentation to install the library.

Then, when initializing the client, pass in your Gateway API key and endpoint instead of defaults:

val openAi = OpenAI(
        token = "YOUR_GATEWAY_API_KEY",
        host = OpenAIHost("https://api.meetgateway.com/v1/proxy/YOUR_ENDPOINT/v1")
)

warning

Remember to suffix your endpoint with /v1 to match the OpenAI API version as the library does not include it when using an alternative host.

Ktor Client

val client = HttpClient(CIO) {
    defaultRequest {
        url("https://api.meetgateway.com/v1/proxy/YOUR_ENDPOINT/")
        header("Authorization", "Bearer YOUR_GATEWAY_API_KEY")
    }
}

Flutter

dio HTTP Client

If you're using the popular dio package for HTTP requests in Flutter, you can easily integrate Gateway by modifying your base URL and adding an authentication interceptor.

final dio = Dio()
  ..options.baseUrl = 'https://api.meetgateway.com/v1/proxy/YOUR_ENDPOINT/'
  ..interceptors.add(
    InterceptorsWrapper(
      onRequest: (options, handler) {
        options.headers['Authorization'] = 'Bearer YOUR_GATEWAY_API_KEY';
        return handler.next(options);
      },
    ),
  );

http Package

If you're using the standard http package, you can create a custom client that adds the Gateway API key to all requests:

class GatewayClient extends http.BaseClient {
  final String apiKey;
  final http.Client _inner;

  GatewayClient(this.apiKey, this._inner);

  @override
  Future<http.StreamedResponse> send(http.BaseRequest request) {
    request.headers['Authorization'] = 'Bearer $apiKey';
    return _inner.send(request);
  }
}

// Usage
final client = GatewayClient(
  'YOUR_GATEWAY_API_KEY',
  http.Client(),
);

// Make requests
final response = await client.get(
  Uri.parse('https://api.meetgateway.com/v1/proxy/YOUR_ENDPOINT/your-endpoint'),
);

tip

Make sure to:

1. Replace YOUR_GATEWAY_API_KEY with your actual Gateway API key
2. Replace YOUR_ENDPOINT with your target API endpoint
3. Add any necessary path segments after the base URL in your API calls
