Dun & Bradstreet
Dun & Bradstreet is a leading global provider of business decisioning data and analytics, anchored by the D-U-N-S Number — a unique nine-digit identifier assigned to more than 500 million businesses worldwide. Founded in 1841 as The Mercantile Agency in New York City and now headquartered in Jacksonville, Florida, D&B operates the D&B Data Cloud, a master commercial database used by enterprises and governments for credit, risk, supply, master data, sales, marketing, compliance, and third-party due diligence. Its primary developer surface is D&B Direct+, a RESTful API platform that lets customers match, enrich, monitor, and stream company data programmatically using OAuth 2.0 access tokens. D&B was taken private by Clearlake Capital in August 2025 for approximately $7.7 billion (including debt).
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles Dun & Bradstreet the way a machine reads it — 95 machine-readable artifacts across 1 API, 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 — Dun & Bradstreet scores 64.0/100 (strong), with a separate agent-readiness read of 45/100 (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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Dun & Bradstreet
Each block below is one kind of artifact we hold for Dun & Bradstreet. 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.

Arazzo Workflows 10
Real integrations are rarely a single call. Arazzo describes the multi-step sequences — auth, then create, then confirm — so both a human and an agent can follow the choreography, not just the endpoints.

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVERPricing 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 things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
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.

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.

Features 8

Notable capabilities this provider offers.
D-U-N-S Number Identity
Every business in the D&B Data Cloud carries a unique nine-digit D-U-N-S Number that acts as a persistent, globally recognized enterprise identifier.
Data Cloud Coverage
More than 500 million company records spanning legal entities, branches, subsidiaries, contacts, and beneficial owners across virtually every country.
Data Blocks
Versioned, domain-grouped attribute bundles (Company, Financials, Hierarchy, Risk, Compliance, ESG, Beneficial Ownership) that callers opt into per request.
Match + Enrich in One Call
Multi-Process combines Identity Resolution and Enrich, eliminating a round-trip for onboarding and CRM-augment workflows.
Synchronous + Batch + Streaming
Direct+ offers REST synchronous calls, Data File asynchronous batch processing, and Monitoring change-notification streams over the same data substrate.
Hierarchy and Linkage
Corporate hierarchies — parent, headquarters, ultimate domestic parent, ultimate global parent, branches — are exposed as first-class relationships rather than denormalized fields.
Beneficial Ownership and Compliance
Enrich includes UBO, sanctions, watchlist, and PEP screening data to support KYB, AML, and third-party risk management programs.
OAuth 2.0 Client Credentials
Authentication is standard OAuth 2.0 client-credentials grant; bearer tokens are scoped per Direct+ subscription.

Event Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.
AsyncAPI definitions for this provider's event-driven and streaming APIs.
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.

Governance rulesets we run against this provider's specs — the automated checks behind parts of the score. Profiling them makes the quality bar explicit and re-runnable, not a matter of opinion.

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.

Security Posture 4
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.

SECURITYScopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.
OAuth scopes governing access to this provider's APIs.
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.
Recommended x-agentic-access execution contracts for AI agents.

We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
