The Predictive Index

The Predictive Index (PI) is a talent optimization platform that pairs 70+ years of behavioral science with software to help organizations hire, engage, and develop teams — behavioral and cognitive assessments, hiring and candidate screening, leadership development, employee engagement, and performance management. PI publishes a RESTful Integration API (on Azure API Management) that lets external systems such as ATS/HRIS platforms programmatically create candidates, send behavioral and cognitive assessments, retrieve jobs and results, and generate insight and coaching-guide reports — the same data that appears in the PI Portal software. Status-change notification webhooks push assessment completion events to listening systems. Backed by a $50M investment from General Catalyst.

agent aware

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 The Predictive Index the way a machine reads it — 8 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 — The Predictive Index scores 51.2/100 (developing), with a separate agent-readiness read of 44/100 (agent aware). 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 The Predictive Index

Each block below is one kind of artifact we hold for The Predictive Index. 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.

The Predictive Index Behavioral Assessments API

The Behavioral Assessments API from The Predictive Index — 1 operation(s) for behavioral assessments.

The Predictive Index Candidates API

The Candidates API from The Predictive Index — 3 operation(s) for candidates.

The Predictive Index Employees API

The Employees API from The Predictive Index — 2 operation(s) for employees.

The Predictive Index Jobs API

The Jobs API from The Predictive Index — 1 operation(s) for jobs.

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.

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.
