OpenAI API client for Kotlin

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

📦 Setup

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

repositories {
    mavenCentral()
}

dependencies {
    implementation "com.aallam.openai:openai-client:3.7.2"
}

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:3.7.2')

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

Multiplatform

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

Maven

Gradle is required for multiplatform support, but there's nothing stopping you from using the jvm client in a Maven project. You still need to add to your dependencies one of Ktor's engines.

Setup the client with maven

<dependencies>
    <dependency>
        <groupId>com.aallam.openai</groupId>
        <artifactId>openai-client-jvm</artifactId>
        <version>3.7.2</version>
    </dependency>
            
    <dependency>
        <groupId>io.ktor</groupId>
        <artifactId>ktor-client-okhttp-jvm</artifactId>
        <version>2.3.2</version>
        <scope>runtime</scope>
    </dependency>
</dependencies>

The BOM is not supported for Maven projects.

⚡️ 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.
