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.
```
