Immutable

Immutable is a games growth and blockchain infrastructure company whose platform spans two connected halves: Immutable Audience, a games-focused CDP, attribution and player-activation stack (ingestion, analytics, engage, conversion funnel, ad-network postbacks), and Immutable Chain, a gaming-optimised Ethereum zkEVM with Passport embedded wallets, pre-built ERC-721/ERC-1155/ERC-20 asset contracts, a gasless Minting API, a Seaport-based decentralised Orderbook, an NFT Indexer and Checkout flows. Developers work against a public REST surface on api.immutable.com described by two published OpenAPI 3.0.3 documents, configure projects and API keys in Immutable Hub, and integrate through first-party TypeScript, Unity and Unreal SDKs.

Immutable publishes 16 APIs on the APIs.io network, including Activities API, Chains API, Collections API, and 13 more. Tagged areas include Company, Gaming, Blockchain, NFT, and Web3.

The Immutable catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Immutable’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, changelog, and 35 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments 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/immutable: open an issue to ask a question, or submit a pull request to add artifacts.
