Foundation

name: Foundation
description: Foundation is a creator-focused NFT marketplace built on Ethereum that enables digital artists to mint, showcase,
  and auction unique digital artworks. The platform provides a GraphQL API via The Graph protocol for querying artwork, auctions,
  bids, collector profiles, offers, buy-now listings, and edition drop data. Foundation smart contracts remain live on Ethereum
  mainnet, and the subgraph continues to index on-chain activity for programmatic access.
