OpenAI API client for Kotlin

Kotlin client for OpenAI's API with multiplatform and coroutines capabilities.

📦 Setup

1. Install OpenAI API Kotlin client by adding the following dependency to your build.gradle file:

repositories {
    mavenCentral()
}

dependencies {
    implementation "com.aallam.openai:openai-client:3.3.0"
}

2. Choose and add to your dependencies one of Ktor's engines.

BOM

Alternatively, you can use openai-client-bom by adding the following dependency to your build.gradle file

dependencies {
    // import Kotlin API client BOM
    implementation platform('com.aallam.openai:openai-client-bom:3.3.0')

    // define dependencies without versions
    implementation 'com.aallam.openai:openai-client'
    runtimeOnly 'io.ktor:ktor-client-okhttp'
}

Multiplaform

In multiplatform projects, add openai client dependency to commonMain, and choose an engine for each target.

⚡️ Getting Started

Note: OpenAI encourages using environment variables for the API key. Read more.

Create an instance of OpenAI client:

val openai = OpenAI(
    token = "your-api-key",
    timeout = Timeout(socket = 60.seconds),
    // additional configurations...
)

Or you can create an instance of OpenAI using a pre-configured OpenAIConfig:

val config = OpenAIConfig(
    token = apiKey,
    timeout = Timeout(socket = 60.seconds),
    // additional configurations...
)

val openAI = OpenAI(config)

Use your OpenAI instance to make API requests. Learn more.
