Sapient Slingshot
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.
