  title: LooksRare Public Collections Seaport API
  description: LooksRare is a community-first NFT marketplace built on Ethereum. The public REST API exposes read and write access to orders, events (listings, sales, offers, cancellations), token metadata, and collection data across Ethereum Mainnet (https://api.looksrare.org) and the Sepolia testnet (https://api-sepolia.looksrare.org). A mainnet API key is required for write operations such as order creation.
