# API Overview

> The LiteLLM Agent Platform REST API.

The LiteLLM Agent Platform exposes a REST API for managing runtimes, agents, and sessions. All endpoints require a `Authorization: Bearer <key>` header (or `?key=<key>` for SSE streams).

## Base URL

| Environment                | URL                                 |
| -------------------------- | ----------------------------------- |
| **Production**             | `https://litellm-rust.onrender.com` |
| **Local (Docker Compose)** | `http://localhost:4000`             |

## Authentication

All endpoints require your master key:

```bash theme={null}
curl https://litellm-rust.onrender.com/api/agents \
  -H "Authorization: Bearer $MASTER_KEY"
```

The default master key for local Docker Compose is `sk-local`.
