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.
