API keys

All WebSocket connections require an API key passed as a query parameter: 
wss://hyper.polynode.dev/ws?key=pn_live_your_key_here
hypernode uses the same API keys as polynode. If you already have a polynode account on the Growth plan ($200/mo) or above, your existing pn_live_ key works on hypernode automatically. Get a key:
  • Sign up at polynode.dev to create an account and get an API key
  • Free tier gets 1 connection and 1 subscription on both polynode and hypernode
  • Growth ($200/mo) and above gets full access to both platforms
