Any update @rajkharvar ?
Its pending since long time and it is a high priority. Please complete asap.

[rajkharvar]

Oops, Sorry I missed this. Will look into this now.

@hrishikeshio It's not possible to query blockchain using simple HTTP GET request. If we want to support uniswap pricefeed though we might need a proxy server which fetches data from blockchain and serve it through GET request.

[hrishikeshio]

Why not? All applications talk to the blockchain using JSON RPC. Check, e.g. https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_call @rajkharvar

Yes, through POST request it's possible but through GET request it's not possible.

@hrishikeshio Tried to fetch blocknumber using GET request from alchemy and infura node, but it's not supported.

I got this error.

Alchemy:

Allowed methods: [POST]","logref":null,"path":null,"_links":{},"_embedded":{}}]}}

Infura:

Compatibility for this has been achieved in razor-network/oracle-node#1020. This will be released in v1.0.6.
