Blockcypher Websocket endpoint not working

Question

I am using the Blockcypher API for test bitcoin transactions and I have troubles with the websocket API endpoint. When sending the regular ping object after creating a new Websocket it works fine:

this.ws.onopen = () => {
  this.ws.send(JSON.stringify({"event": "ping"})) 

but when trying to check the confidence of a transaction like this we get an error

this.ws.onopen = () => { this.ws.send(JSON.stringify({event: 'tx-confidence', address:'<bitcoin address as string>', confidence:0.9}))

Is there anything wrong with the datatypes? Any help would be great!

API reference Event reference

You probably reached the limit. Consider adding your BlockCypher token at the end of the websocket URL. This was somehow forgotten in the documentation.
