Insperity
Insperity is a professional employer organization (PEO) headquartered in Kingwood, Texas that provides human resources and business performance solutions to small and medium-sized businesses, including payroll processing, employee benefits, workers' compensation, HR compliance and the Insperity Premier HR technology platform. Insperity Premier exposes a REST Public API at https://api.insperity.com/public organized into four categories — Onboarding, Payroll & Tax, HRIS and Core — covering 45 publicly listed operations that let a client's applicant tracking system, HRIS or payroll application send new-hire records, submit employee change events, retrieve post-payroll general ledger data, and read the company-scoped reference code lists those writes must resolve against. Access is not self-service: a key is issued per customer by an Insperity Integration Specialist after an API Terms of Use Agreement is signed, requests must originate from allow-listed IP addresses, and the developer portal's Swagger documents require a Premier account.
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 Insperity 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 — Insperity scores 14.3/100 (emerging), with a separate agent-readiness read of 11/100 (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. 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 Insperity
Each block below is one kind of artifact we hold for Insperity. 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.
Insperity Onboarding API
Use your own applicant tracking or HR application to send candidate hire information to Insperity Premier Onboarding. One published operation, POST /public/Employee/Onboarding/v...
Insperity Payroll & Tax API
Update an employee's compensation and retrieve general ledger information post payroll. Three published operations covering billing group changes, remuneration changes and the p...
Insperity HRIS API
Transfer employee information to and from Insperity Premier. Twenty-six published operations — fifteen named employee change events written as POSTs (address, email, phone, depa...
Insperity Core API
Company-scoped reference data. Some Insperity API fields require specific values as defined in Insperity Premier, and the Core APIs return the list of accepted options — benefit...
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 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.

RATE LIMITSSecurity 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.

The organization behind the API

This is an independent, third-party profile of Insperity, published by API Evangelist. 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.
