DataCite

DataCite is a leading global non-profit organization that provides DOI (Digital Object Identifier) registration and persistent identifier services for research outputs, enabling researchers to cite, discover, and access scholarly data. DataCite maintains a REST API for minting and managing DOIs, querying metadata records, and accessing the global research data graph. Membership-based access allows institutions to register DOIs through APIs and the Fabrica web interface, while public metadata retrieval is freely available to anyone. DataCite also offers a GraphQL API, a legacy Metadata Store (MDS) API, usage statistics via its Usage Reports API, and scholarly event tracking via the Event Data API.

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 DataCite the way a machine reads it — 24 machine-readable artifacts across 16 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 — DataCite scores 45.1/100 (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 DataCite

Each block below is one kind of artifact we hold for DataCite. 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 16

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.

DataCite GraphQL API

An alternative query interface for DOI metadata retrieval using the GraphQL query language. Currently supports queries only (no mutations or subscriptions). Publicly accessible ...

DataCite Event Data API

Tracks mentions, citations, and scholarly events related to registered DOIs. Enables discovery of how research outputs are referenced and linked across the scholarly web.

DataCite publishers API

The publishers API from DataCite — 2 operation(s) for publishers.

DataCite report_types API

The report_types API from DataCite — 1 operation(s) for report_types.

DataCite repositories API

The repositories API from DataCite — 2 operation(s) for repositories.

DataCite status API

The status API from DataCite — 1 operation(s) for status.

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.

GraphQL schemas published by this provider.

The DataCite GraphQL API provides a flexible query interface for retrieving DOI metadata and the broader research knowledge graph. It exposes the full DataCite metadata model th...

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.

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.

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.

Cost, billing, and metering signals for API financial operations.

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.

JSON-LD contexts and semantic vocabularies used across these APIs.

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.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
