Any Realtime DEX Data i.e Price,Transactions, Market Cap, Volume etc

Hi everyone,

I wanted to make a trading platform like Photon/BullX. I have figured some parts but I cannot find realtime DEX data providers who can give me prices, transaction, Market Cap, Volume and Liquidity etc to show in the UI or for realtime analysis.

I have looked into CoinGecko but all they provide is REST API’s so I think I would have to poll those endpoints which is not a good idea IMO

So please if you guys can me give me any names of services or pointers on how to get this kinda realtime data over streams like websockets or gRPC. I am willing to pay upto $1K for the service.

Thanks.
