JSONRPC or REST interface to cardano-node, or a lightweight socket library

[Nye_Liu]

I see this answers my question more or less, as a conclusive no, other than the Haskell native IPC API which I do not think has any non-haskell way of talking to it.

Cardano Node API's document

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.
