Factorial
Factorial is an all-in-one HR, payroll, time, talent, finance, and IT management platform headquartered in Barcelona, Spain, used by 16,000+ companies worldwide. The Factorial public API is a date-versioned REST API (current major 2026-04-01 "Legendre") covering employees, contracts, attendance, time off, payroll, ATS, performance, trainings, projects, finance, banking, procurement, IT assets, documents, webhooks, and an Approvals workflow surface. Authentication uses OAuth2 (on behalf of a user) or an x-api-key header (on behalf of the company), with 30+ scopes for granular partner access. Factorial publishes the OpenAPI schema and generated SDKs (Ruby, Python, Java, PHP, TypeScript, Node.js) at github.com/factorialco/oas and exposes an llms.txt index for AI agents.
Factorial is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
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. The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Factorial is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
