[New Content]: How to obtain real-time trading pair data

[86driver]

What would you like us to add?

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?

What should I do?

How important it is?

The most important thing is that I can't find where to apply for the apikey
