I am trying to get listings and/or the latest bids for the same ERC721 token from different marketplaces (such as Opensea or Looksrare). I know that those platforms have their own APIs but none are commercially available.
Any of the following solutions will be enough to fix the problem
- retrieving the listing details since I know the collection address and the contract addresses of those marketplaces (either using Etherscan or any other commercially available API)
- retrieving the latest/highest bid for that token associated with marketplaces (either using Etherscan or any other commercially available API)
