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 2 APIs on the APIs.io network: zkEVM API and Audience API. 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 33 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.

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/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. 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. Want it done for you? Prioritized profiling — $2,500 →
