View Developer's KitOpenSea provides an HTTP API for fetching non-fungible ERC721 assets based on a set of query parameters. Wallets and websites can now display:
Get assets filtered by a particular collectible type, or belonging to a particular wallet address
Get events happening on all assets (not just on our marketplace), including sales, listings, bids, transfers, and more
Get usernames and profile details for account addresses

With over 4 million assets, 135+ dapps, and 4,000 ETH in monthly volume, OpenSea is the largest marketplace for the decentralized web. We've built a set of robust marketplace tools, and we're making them openly available for developers.
