Diligent
Diligent Corporation is a governance, risk, and compliance (GRC) software company best known for its board management portal (Diligent Boards / Boardbooks) and the broader Diligent One Platform, which unifies board management, enterprise risk, audit, compliance, entity management, and ESG. The board portal itself is a security-hardened product with no public developer API - it is integrated through SSO (SAML 2.0), SCIM provisioning, and packaged connectors (Okta, Microsoft 365/Teams, Zoom, DocuSign). Diligent does, however, publish a real developer portal at developer.diligent.com covering the GRC side of the platform - the HighBond (Diligent One) REST API for audit/risk/compliance data, a GraphQL Entities API for legal-entity and subsidiary management, an ESG API for activity/usage data, and a Workflow API for jobs, tasks, and campaigns. API access is customer/partner-gated (a HighBond API key or SSO-scoped token is required) and pricing is quote-based via Diligent sales.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Diligent the way a machine reads it — 7 machine-readable artifacts across 4 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 — Diligent scores 15.4/100 (emerging), with a separate agent-readiness read of 0/100 (human only). 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 Diligent
Each block below is one kind of artifact we hold for Diligent. 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 4
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.

Security Posture 3
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.
