SDKs and CLI

This page covers the main ways to build with the OpenAI API: official SDKs for application code, the OpenAI CLI for shell-native workflows, the Agents SDK for orchestration, or your own preferred HTTP client.

Create and export an API key

Before you begin, create an API key in the dashboard, which you'll use to securely access the API. Store the key in a safe location, like a .zshrc file or another text file on your computer. Once you've generated an API key, export it as an environment variable in your terminal.

export OPENAI_API_KEY="your_api_key_here"

setx OPENAI_API_KEY "your_api_key_here"

OpenAI SDKs are configured to automatically read your API key from the system environment.

Install an official SDK

Use the Agents SDK

Use the official OpenAI SDKs above for direct API requests. Use the Agents SDK
when your application needs code-first orchestration for agents, tools,
handoffs, guardrails, tracing, or sandbox execution.

• OpenAI Agents SDK for TypeScript
• OpenAI Agents SDK for Python

Azure OpenAI libraries

Microsoft's Azure team maintains libraries that are compatible with both the OpenAI API and Azure OpenAI services. Read the library documentation below to learn how you can use them with the OpenAI API.

• Azure OpenAI client library for .NET
• Azure OpenAI client library for JavaScript
• Azure OpenAI client library for Java
• Azure OpenAI client library for Go

Community libraries

The libraries below are built and maintained by the broader developer community. You can also watch our OpenAPI specification repository on GitHub to get timely updates on when we make changes to our API.

Please note that OpenAI does not verify the correctness or security of these projects. Use them at your own risk!
