PayFit
PayFit is a cloud-based payroll and HR platform serving small and mid-sized businesses in France, the United Kingdom, Spain, Germany, and Italy with automated payroll, expense management, leave and time tracking, and employee self-service. The platform handles country-specific payroll calculations, tax filings, and social declarations alongside core HR workflows. PayFit exposes two REST APIs: a Customer API authenticated via private API keys for direct company-data access, and a Partner API using OAuth 2.0 for integration developers building marketplace solutions.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles PayFit the way a machine reads it — 23 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 — PayFit scores 26.5/100 (thin), with a separate agent-readiness read of 22/100 (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 PayFit
Each block below is one kind of artifact we hold for PayFit. 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 9
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.
PayFit Partner API
OAuth 2.0 REST API for solution developers building integrations with PayFit. Once enabled by a customer, partners can synchronize collaborators, payroll journals, meal vouchers...
PayFit Customer API
Private REST API for PayFit customers to access their own company data via long-lived private API keys, suitable for in-house scripts and direct integrations.
PayFit Absences API
The Absences API from PayFit — 1 operation(s) for absences.
PayFit Collaborators API
The Collaborators API from PayFit — 2 operation(s) for collaborators.
PayFit Company API
The Company API from PayFit — 4 operation(s) for company.
PayFit Contracts API
The Contracts API from PayFit — 2 operation(s) for contracts.
PayFit Documents API
The Documents API from PayFit — 1 operation(s) for documents.
PayFit Insurance API
The Insurance API from PayFit — 3 operation(s) for insurance.
PayFit Payslips API
The Payslips API from PayFit — 2 operation(s) for payslips.

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.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
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.

This is an independent, third-party profile of PayFit, 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.
