IOTA

IOTA is an open-source distributed ledger technology built to bring real-world applications on-chain. It is the first internet-scale programmable blockchain platform powered by the Move programming language with horizontal scaling, feeless transactions, and a unique parallel transaction processing model. IOTA exposes a JSON-RPC 2.0 API over HTTP and a GraphQL RPC for querying objects, checkpoints, transactions, coins, events, and on-chain state on Mainnet, Testnet, and Devnet networks. The platform targets trade and supply chains, decentralized finance, digital identity, real-world asset tokenization, and product lifecycle management.

IOTA publishes 16 APIs on the APIs.io network, including auth API, chains API, Coin Query API, and 13 more. Tagged areas include Blockchain, Distributed Ledger, Web3, DeFi, and Cryptocurrency.

The IOTA catalog on APIs.io includes 1 JSON-LD context.

IOTA’s developer surface includes authentication, developer portal, documentation, getting-started guide, API reference, CLI, engineering blog, and 27 more developer resources.

Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against 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 80 points between them, because the conditional facet above carries the other 20. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 80% 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/iota: open an issue to ask a question, or submit a pull request to add artifacts.
