Art Blocks Plans
Art Blocks does not publish tiered commercial pricing plans for its public APIs. The Token API, Generator API, and Media Proxy API are freely accessible without authentication or API keys. The Hasura GraphQL API (data.artblocks.io) is publicly accessible but requires JWT authentication for queries that request off-chain data or write operations; tokens are obtained via the Art Blocks authentication endpoint. The Graph subgraph endpoints require a developer API key from The Graph Network studio. The MCP Server (mcp.artblocks.io) uses OAuth 2.1 and is available to any developer after a one-time sign-in.
