The official TypeScript SDK for OpenSea, the largest NFT marketplace. It lets developers access the orderbook, create and fulfill listings and offers, complete trades programmatically, and swap tokens across chains.

Use cases

  • create NFT listings and offers programmatically
  • fulfill OpenSea orders onchain from a bot
  • query the OpenSea orderbook and filter NFT listings
  • fetch collection stats like floor price and volume
  • build an NFT trading bot for OpenSea
  • swap tokens across chains via OpenSea
  • mint and deploy NFT contracts

When to choose

  • you want to build on the OpenSea marketplace with an official, maintained SDK
  • you need programmatic order creation and fulfillment on Ethereum and other supported chains
  • you prefer TypeScript/JavaScript with ethers.js or viem integration

When to avoid

  • you need a marketplace-agnostic NFT solution not tied to OpenSea
  • you work in a language other than JavaScript/TypeScript
  • you only need read-only NFT data without trading, where a simple API client may suffice
