  Publicis Groupe is the French-headquartered global marketing, communications and
  business-transformation holding company behind Publicis Sapient, Publicis Media,
  Epsilon, CJ Affiliate, Leo Burnett, Saatchi & Saatchi, Digitas and Razorfish. The
  Groupe itself runs no public developer program and publishes no API at
  publicisgroupe.com; its machine-readable surface is produced by the operating
  units. The largest publicly readable one is the Publicis Sapient KnowHOW suite —
  an Apache-2.0 engineering-KPI platform (knowhow-api / knowhow-ui / knowhow-common /
  knowhow-processors on GitHub, container psknowhow/knowhow-api on Docker Hub) whose
  Spring Boot service self-documents an OpenAPI at /api/v3/api-docs on whatever host
  an operator deploys it to, plus knowhow-mcp, a self-hosted MCP server exposing the
  KnowHOW documentation assistant. Alongside it Publicis Sapient publishes the
  @psnext npm scope — the sling CLI for the Sapient Slingshot enterprise LLM gateway,
  the lscg local source-context-graph CLI and stdio MCP server, and the Block SDK for
  building iframe Blocks on Publicis Groupe's CoreAI platform. Epsilon and
  CJ Affiliate, which do publish hosted API contracts, are profiled in their own
  API Evangelist repositories.

    KnowHOW is Publicis Sapient's open-source (Apache-2.0) engineering measurement
    platform — a KPI dashboard that pulls from Jira, source control, CI and quality
    tools and reports delivery health across transformation programmes. It is a
    self-hosted product, not a hosted API: the Spring Boot service is served under the
    /api context path and generates its own OpenAPI 3 document at /api/v3/api-docs
    (Swagger UI at /api/swagger-ui/index.html) on whatever host the operator deploys,
    so no single public base URL exists and API Evangelist did not capture a static
    spec. Authentication is a session cookie (authCookie) or an x-api-key header.

  description: >-
    Sapient Slingshot is Publicis Sapient's proprietary AI software-engineering
    platform — an enterprise LLM gateway plus a family of agents for legacy
    modernization, spec generation and code delivery. The client surface published to
    the public is the npm package @psnext/slingcli, which installs a `sling` CLI that
    authenticates to Slingshot over a browser OAuth flow (/login slingshot) or a
    pre-issued SLINGSHOT_TOKEN bearer token and then routes to the gateway's model
    catalogue. The gateway's HTTP contract itself is not published; the only gateway
    host observed in first-party source is an internal one that does not resolve on
    the public internet, so no base URL is recorded.
