Two-minute setup

1. Create a free TokenReply account.
2. Create an API key on the API keys page (walkthrough) and copy the value that starts with sk-.
3. Send your first request:

curl https://api.tokenreply.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $TOKENREPLY_API_KEY" \
  -d '{
    "model": "grok-4.20-fast",
    "messages": [{"role": "user", "content": "Explain recursion in one paragraph."}]
  }'

Need more than the free models?

Other Grok models are available as Weekly Featured or paid models; their access and prices are on the models page. Free and paid models use the same base URL and key, so switching only changes the model ID.
