Requesting resources from different addresses in a bunch

Describe your question in detail.

Hello,

I want to create a smart contract to help me to pull all the needed information with a single request, instead of 1 request per address.

I have a webpage with charts (real-time prices of different pools) and for every pool I have to make 1 request, which is slow (request by request) or overloaded (requests in parallel). Theoretically I need to get the price every 500ms or 1sec, per pool.

I though to make a smart contract where I give as input 3 lists: pools: vector<address>, coinsA: vector<CoinType>, coinsB: vector<CoinType>.
And inside of the function to access the resource: pools[i].getResource(0x0::mod::ResX<coinsA[i], coinsB[i]> - I know this is not right, but is for describing my idea.
Or instead of coinsA and coinsB to have resources: vector<Resources> and to do pools[i].getResource(resources[i]).

It is possible any of these? Or any other way, to reduce the multiple requests to a single one? I am open to use any SDK if that helps me to achieve my target.

Thank you.

if you know the address that hold the resource and the resource type, you can call multiple borrow_global in a single contract, can you try this approach?
