Accessing data on the Ethereum Blockchain

I am looking for someone to help me understand how to access data on the Ethereum blockchain and then write a C# .NET application to access this data.

The following website allows users to buy and sell NFTs.

https://l2beat.com/projects/sorare/

Each time someone puts a NFT for sale a Single Sale Offer is created.

You can view the Single Sale Offers here;

https://api.sorare.com/graphql/playground

Using this query;

query {
transferMarket {
singleSaleOffers {
nodes {
id
blockchainId
card {
slug
}
}
}
}
}

Each Single Sale Offer has a Blockchain Id.

I would like to first understand if I can view this Single Sale Offer on the Ethereum blockchain?
If that is possible I would like C# .NET code to be able to get the latest Single Sale Offers.
