OpenSea API is a developer API to build custom marketplaces powered by Ethereum smart contracts.
EthereumOpenSea API is a developer toolkit introduced in 2018 that enables building custom marketplaces powered by Ethereum smart contracts.
It allows developers to run auctions in any currency, including their own tokens, and to view analytics through OpenSea.js.
Listings require NFTs to be ERC721 or ERC1155 compliant.
The API is free to use, but access to an API key is granted only after submitting an application form and awaiting approval.
