LayerX

aid: layerx
name: LayerX
description: 'LayerX Inc. (株式会社LayerX) is a Tokyo-based enterprise software company founded 1 August 2018, operating as a
  compound startup across four business lines: Bakuraku (バクラク), an AI back-office suite covering expense reimbursement, invoice
  receipt and issuance, workflow and approvals, electronic bookkeeping, attendance, payroll and a corporate card; Ai Workforce,
  an enterprise LLM document-processing platform; a Fintech business run through the Mitsui-X / Mitsui & Co. Digital Asset
  Management joint venture; and a Security business added through the April 2026 acquisition of AgenticSec Inc. Its developer
  surface is the Bakuraku API — a REST API at api.bakuraku.layerx.jp built on an internal unified GraphQL gateway and tsoa,
  exposing application/approval retrieval and creation, attachment download, and tenant user, group and position directories.
  API access is granted by application to existing Bakuraku customers, who are issued a scoped API key from the Bakuraku admin
  console; the API reference at /rest/docs/ is HTTP Basic protected and no OpenAPI definition is published publicly.'

  description: 'REST API for the Bakuraku (バクラク) back-office suite. Publicly documented capabilities are retrieval and list-search
    of applications/requests (申請), download of attached files, creation of applications for the purchase-request, payment-request
    and general-purpose application types, and read access to the tenant user, group and position directory. Bakuraku 請求書発行
    additionally exposes document upload (CSV/PDF) and recipient-master create/update. Authentication is a scoped API key
    issued from the Bakuraku admin console (API管理). Access requires an existing Bakuraku contract plus a separate API application;
    the reference at https://api.bakuraku.layerx.jp/rest/docs/ answers HTTP 401 with WWW-Authenticate: Basic to anonymous
    callers and no OpenAPI is published.'

  detail: 'The Bakuraku REST API is live and reachable at https://api.bakuraku.layerx.jp/rest — it answers anonymous calls
    with its own JSON error envelope and an x-layerx-request-id header — but its reference at /rest/docs/ sits behind HTTP
    Basic auth at the AWS load balancer (401, WWW-Authenticate: Basic), issued only to companies LayerX has approved as an
    "API契約者" on top of an existing Bakuraku subscription, and the API terms state the specification document is supplied separately
    to those customers, so no OpenAPI exists at any public URL.'
