Buk

Buk (Buk SpA, Santiago, Chile) is a Latin American HR and payroll platform — "software de gestión de personas" — covering payroll and settlement calculation, employee records, contracts and digital signature, time and attendance, absence and vacation management, benefits and salary advances, recruitment, onboarding, training and performance. Founded in 2017 and bootstrapped for its first five years, it raised a $50M Series A led by Greenoaks and SoftBank in 2021 and a further $50M Series B in 2024, and now operates country editions for Chile, Peru, Mexico, Colombia and Brazil. Its API posture is unusual for the region and unusually good in one specific way: every customer tenant serves a complete, unauthenticated, machine-readable Swagger 2.0 contract for the Buk Data Access API at https://{tenant}.buk.cl/api/{country}/{language}/api_docs — 151 paths and 206 operations, in five country variants and three languages — behind a Swagger UI at /apidocs, alongside a documented webhook catalog. Two further contracts for Buk Asistencia (attendance) and its vendor-agnostic biometric clocking ingestion endpoint are published publicly on SwaggerHub under the BUKASISTENCIA account. What is missing is the developer-program scaffolding around those contracts: there is no developer portal, no first-party SDK, no CLI, no Postman workspace, no status page, no sandbox, no /.well-known/ surface, no MCP server, no operationId on any of 206 operations, and no documented rate limit or 429 response. The contract is public; the program around it is not built yet.

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.

API Evangelist profiles Buk the way a machine reads it — 138 machine-readable artifacts across 66 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 — Buk scores 51.3/100 (developing), with a separate agent-readiness read of 45/100 (agent ready). 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 Buk

Each block below is one kind of artifact we hold for Buk. 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 66

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.

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

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.

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.

Where this information came from

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