Thank You!
As per my understanding cardano-db-sync will run on top of our local node only and graphql, cardano-rest, PostgREST are on top of cardano-db-sync.
So, without using cardano-db-sync, are there any API’s available which will communicate with node directly.
For e.g., cardano node is running locally and port 1234 is required to be opened then we will get the block information using below GET request http://localhost:1234/block?1.
