Manifold

Manifold is an NFT creator tools platform that empowers artists and developers to deploy their own creator-owned smart contracts, mint NFTs, and build custom on-chain experiences without relying on platform-specific custody. Founded in 2021, Manifold provides a no-code studio (Manifold Studio) for ERC721 and ERC1155 contract deployment, open-source Creator Core smart contracts, a Royalty Registry adopted by all major NFT marketplaces, and a Client SDK for building custom minting dApps. The platform supports Ethereum Mainnet, Base, Optimism, Shape, Apechain, and Sepolia testnet. Manifold also exposes server-side authentication APIs (Signature Grant and Authorization Code Grant via oauth2.manifoldxyz.dev), a Studio Apps REST API (apps.api.manifoldxyz.dev) for product and minting data, open-source Solidity extension contracts for custom mint mechanics, and a Marketplace contract powering auction and fixed-price listings. Gas fees are the only cost for creators; Manifold charges no platform fees or royalties on sales.

Manifold publishes 7 APIs on the APIs.io network, including Authorization Code Grant API, Signature Grant API, and 5 more. Tagged areas include NFT, Creator Tools, Smart Contracts, Blockchain, and Web3.

The Manifold catalog on APIs.io includes 1 Spectral governance ruleset.

Manifold’s developer surface includes documentation, GitHub presence, engineering blog, and 12 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/manifold: open an issue to ask a question, or submit a pull request to add artifacts.
