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.

agent ready

Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.

Kin Score

API Evangelist profiles IOTA the way a machine reads it — 41 machine-readable artifacts across 17 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — IOTA scores 54.6/100 (developing), with a separate agent-readiness read of 48/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile IOTA

Each block below is one kind of artifact we hold for IOTA. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 17

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

GraphQL RPC interface for the IOTA blockchain, providing an alternative to the JSON-RPC API. Supports querying transaction blocks, objects, checkpoints, events, and on-chain sta...

IOTA auth API

The auth API from IOTA — 2 operation(s) for auth.

IOTA chains API

The chains API from IOTA — 18 operation(s) for chains.

IOTA Coin Query API

Coin and balance queries: balances, coins list, metadata, supply

IOTA corecontracts API

The corecontracts API from IOTA — 18 operation(s) for corecontracts.

IOTA Extended API

IOTA Health API

The Health API from IOTA — 1 operation(s) for health.

IOTA metrics API

The metrics API from IOTA — 3 operation(s) for metrics.

IOTA Move Utils API

GraphQL 1

Where a provider ships GraphQL, the schema is the contract. We profile it alongside the REST surface so the whole interface is legible in one place.

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Published pricing tiers and plan structures.

Iota Plans

3 plans

PLANS

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

Iota Rate Limits

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Semantic Vocabularies 1

JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

Security Posture 2

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
