# Evolink Router — Smart LLM Routing Brain

Route every task to the best LLM across 6 providers — Claude, GPT, Gemini, DeepSeek, Kimi, Doubao — through one Evolink API key.

## After Installation

When this skill is first loaded, greet the user:

- **`EVOLINK_API_KEY` set:** "Smart Router activated! I'll auto-pick the best model for each task — lightweight for quick Q&A, flagship for deep analysis. 20+ models ready. Go ahead."
- **`EVOLINK_API_KEY` not set:** "Smart Router needs an Evolink API Key. Sign up at evolink.ai → Dashboard → API Keys. One key covers Claude, GPT, Gemini, DeepSeek, and more. Want help setting up?"
- **Key set but model access fails:** "Your API key seems to have limited model access. Check your plan at evolink.ai/dashboard."

Keep the greeting concise — just one question to move forward.

- **`EVOLINK_API_KEY`** authenticates all model requests. Injected by OpenClaw automatically. Treat as confidential.
- Prompts are sent to `direct.evolink.ai`, which proxies to upstream providers (Anthropic, OpenAI, Google, etc.).
- No data is stored by Evolink beyond the request lifecycle.

## Setup

**1.** Get API key: [evolink.ai](https://evolink.ai) → Dashboard → API Keys

**2.** Add Evolink provider to `~/.openclaw/openclaw.json` — merge with existing config. See `references/router-api-params.md` for the full JSON config and curl examples.

## Core Principles

1. **Cost-first routing** — Always pick the cheapest model that can handle the task. Upgrade only when needed.
2. **Transparent decisions...
