TypeScript SDK for the OpenSea marketplace helps developers build new experiences using NFTs and our marketplace data
OpenSea.js
This is the TypeScript SDK for OpenSea, the largest marketplace for NFTs.
It allows developers to access the official orderbook, filter it, create listings and offers, 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 in the process.
Happy seafaring! ⛵️
