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.
Buk publishes 66 APIs on the APIs.io network, including Absences requests API, Accounting Structures API, Applicant API, and 63 more. Tagged areas include Human Resources, Payroll, HR Tech, Time and Attendance, and Benefits.
The Buk catalog on APIs.io includes 1 event-driven AsyncAPI specification.
Buk’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, changelog, pricing, and 41 more developer resources.
