Plans
Foundation's subgraph API is provided through The Graph's hosted service (now transitioning to The Graph Network). Access to the subgraph is free for query use but requires an API key from The Graph Studio for production use on the decentralized network. Smart contract interactions require paying Ethereum gas fees for on-chain transactions.
Plans is the machine-readable pricing-plan profile for Foundation on the APIs.io network, conforming to the API Commons Plans specification.
It defines 3 plans, with named plans including Free Subgraph Query (Hosted Service), The Graph Network (Production), Smart Contract (On-Chain).
Tagged areas include NFT, Digital Art, Marketplace, Ethereum, and Web3.
Plans
Free access to the Foundation FND subgraph via The Graph's legacy hosted service endpoint. No API key required. Suitable for development and low-volume queries. Subject to rate limits imposed by The Graph hosted service infrastructure.
Production access to Foundation subgraph data via The Graph's decentralized network. Requires an API key from Subgraph Studio. Billing is handled through The Graph's GRT-based query fee system, charged per query to indexers on the network.
Direct interaction with Foundation smart contracts on Ethereum mainnet via any Ethereum JSON-RPC provider (Alchemy, Infura, etc.). Read operations (view/pure functions) are free; write operations (mint, bid, accept offer) require Ethereum gas fees.
