Route LLMs for free.
Zero cost, zero friction.

Set up zerocost-router for me.

## What is zerocost-router?
A proxy API that provides an OpenAI-compatible endpoint backed by free-tier LLM providers (Groq, Cerebras, HuggingFace).
Endpoint base URL: https://zerocost-router.dragonrondo.workers.dev/v1

## Setup steps

### Step 1: Issue a zc-key
curl -s -X POST https://zerocost-router.dragonrondo.workers.dev/v1/keys
→ Save the "key" value from the response (e.g. zc-xxxxxxxx...)

### Step 2: Get a free Groq API key
Sign up at https://console.groq.com and generate an API key.

### Step 3: Register the provider key
curl -X POST https://zerocost-router.dragonrondo.workers.dev/v1/keys/providers \
  -H "Authorization: Bearer <zc-key>" \
  -H "Content-Type: application/json" \
  -d '{"provider_id":"groq","api_key":"<groq-api-key>","priority":0}'

### Step 4: Verify it works
curl -X POST https://zerocost-router.dragonrondo.workers.dev/v1/chat/completions \
  -H "Authorization: Bearer <zc-key>" \
  -H "Content-Type: application/json" \
  -d '{"model":"gpt-4o-mini","messages":[{"role":"user","content":"Hello"}],"max_tokens":50}'

### Step 5: Use with OpenAI SDK
base_url = "https://zerocost-router.dragonrondo.workers.dev/v1"
api_key  = "<zc-key>"
Use these settings in place of the standard OpenAI client configuration.

Once done, let me know the zc-key you received.
