Art Blocks

Art Blocks is the leading on-chain generative art platform where artists deploy deterministic code to Ethereum, Arbitrum One, and Base; each token is minted by invoking the script with a unique hash, producing a one-of-a-kind artwork stored permanently on-chain. The platform exposes four public API surfaces: a Token API that returns ERC-721 metadata conforming to the OpenSea standard, a Generator API that serves an iframe-able live view of each artwork, a Media Proxy API that provides static PNG renders, and a Hasura GraphQL API (data.artblocks.io) that gives structured access to on-chain and off-chain data including projects, tokens, artists, features, minting configuration, and ownership. Decentralised access is available through The Graph subgraph for on-chain-only data across all three networks. An MCP Server with 21 tools enables AI-agent integration for querying, minting, and generative script scaffolding.

Art Blocks publishes 7 API contracts indexed on the APIs.io network, including Generator API, Media API, and 5 more. Tagged areas include Generative Art, NFT, On-Chain Art, Blockchain, and Ethereum.

The Art Blocks catalog on APIs.io includes 1 Spectral governance ruleset.

Art Blocks’ developer surface includes engineering blog, documentation, and 11 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
