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.

The Predictive Index publishes 4 APIs on the APIs.io network, including Behavioral Assessments API, Candidates API, Employees API, and 1 more. Tagged areas include Company, Talent Optimization, HR, Human Resources, and Assessments.

The The Predictive Index catalog on APIs.io includes 1 event-driven AsyncAPI specification.

The Predictive Index’s developer surface includes documentation, API reference, getting-started guide, authentication, engineering blog, support, pricing, and 17 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/the-predictive-index: open an issue to ask a question, or submit a pull request to add artifacts.
