[86driver]

Description
i want o obtain real-time trading pair data

Your Environment
Go, js

Additional Information
i want o obtain real-time trading pair data, I found the following related content

• data feed
  But it is not real-time
• data stream
  Must be obtained through apikey, no method to obtain apikey was found
• Streams Trade
  I don't know much about Streams Trade, and I have two questions:
  1. Can this obtain transaction pair data in real time off-chain?
  2. Does Streams Trade also require a data stream API key?
