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

Question

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)

Answer 1

you should give module a shot! They have all data from most NFT marketplaces, I hope that's what you're looking for

Answer 2

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.
