Is there an API to retrieve ERC-721 listings/bids from different marketplaces?

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)

This is an excellent question. The market is completely fragmented and for one to retrieve all the available pricing/listings/orders it needs a lot of legwork and connection to various APIs.

There are a few teams working on a common pricing API that can aggregate the pricing of an asset across exchanges and on multiple chains but none of them is public yet. One of that I know and I'm a beta user of is:

I also believe that Zora.co has a similar endpoint but only for the marketplaces that are built using their own API.
