openapi: 3.0.1
info:
  title: Henchman API
  description: >-
    Henchman is a legal knowledge and contract-drafting AI platform that surfaces a
    firm's own past clauses and definitions from its document management system inside
    Microsoft Word, Outlook, and Copilot. As of this writing Henchman does NOT publish
    a public, documented developer API or API reference. Henchman operates internal
    application API endpoints (under *.henchman.io, covering Dashboard, Auth, Add-in,
    and API surfaces, as referenced in its public bug bounty scope) that power its
    add-ins and document management system connectors, but these are not documented
    for third-party developers and their request/response contracts are not public.
    No endpoints are fabricated here. This paths object is intentionally empty to
    reflect the real, honestly documented surface. The integration surface that is
    documented for customers is the set of supported DMS connectors (iManage,
    NetDocuments, SharePoint, OneDrive, Google Drive, OpenText eDocs) configured via
    service accounts and setup guides, plus the Microsoft 365 add-ins - not a
    self-serve REST API. Henchman was acquired by LexisNexis in 2024 and is being
    integrated into Lexis+ AI and Lexis Create+.
