# Cline API

> Programmatic access to AI models through an OpenAI-compatible Chat Completions API.

Welcome to the Cline API documentation. Use the same models that power the Cline extension and CLI from any language, framework, or tool that speaks the OpenAI format.

## What is the Cline API?

The Cline API is an OpenAI-compatible Chat Completions endpoint. You authenticate once with a Cline API key and get access to models from Anthropic, OpenAI, Google, and more through a single base URL. No need to manage separate keys for each provider.

```
Your App  →  Cline API (api.cline.bot)  →  Anthropic / OpenAI / Google / etc.
```
