Foundation GraphQL API
Foundation was a creator-focused NFT marketplace built on Ethereum that enabled digital artists to mint, showcase, and auction unique digital artworks. The platform exposed a GraphQL API via The Graph protocol, indexing all on-chain activity from Foundation smart contracts on Ethereum mainnet. Foundation shut down its marketplace in April 2026, but the subgraph continued indexing historical on-chain data and may remain accessible for historical queries.
