Automating desktop and browser tasks with AI has shifted from experimental curiosity to production-grade capability. The described computer use API enables models to observe a screen, reason about what they see, and execute actions like clicking, typing, and scrolling. OpenClaw, described as an open-source orchestration framework for computer use APIs, manages screenshot capture, action execution, and session state so developers write only task logic instead of stitching together six discrete concerns by hand. This guide walks through the full integration pipeline, from environment setup to production deployment, with illustrative JavaScript and Node.js code at every step. Important: GPT-5.4 and OpenClaw are not verified as publicly available products at the time of writing. The model identifier gpt-5.4-computer-use does not appear in the OpenAI public model listing, and the @openclaw/cli and @openclaw/sdk packages have not been verified on the npm registry. This guide is illustrative and forward-looking.…
