OpenSea.js

This is the JavaScript SDK for OpenSea, the largest marketplace for NFTs.

It allows developers to access the official orderbook, filter it, create buy orders (offers), create sell orders (listings), and complete trades programmatically.

Get started by requesting an API key and instantiating your own OpenSea SDK instance. Then you can create orders off-chain or fulfill orders on-chain, and listen to events (like ApproveAllAssets or WrapEth) in the process.

Happy seafaring! ⛵️
