Publicis Groupe

name: Publicis Groupe
description: 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.

  name: Publicis Sapient KnowHOW
  description: '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.'

  name: Sapient Slingshot
  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.
