description: 'Tzafon is a machine intelligence company with offices in San Francisco, Tel Aviv, and Zurich, advancing multimodality,
  high performance compute, and continuous learning. Its developer platform Lightcone is the computer-use API: cloud browsers
  and desktops operated by Northstar, a vision-language model trained with GUI reinforcement learning to see screens and act
  on them. Developers describe work in plain language and Northstar operates a computer from start to finish, or they drive
  computers directly through a REST API, official Python and TypeScript SDKs, a CLI, and an official MCP server -- with OpenAI-compatible
  Responses and Chat Completions endpoints for drop-in computer-use loops.'

  name: Lightcone API
  description: The Lightcone API by Tzafon provides cloud browser and desktop computers operated by AI. It spans an agent
    Tasks API (start, stream, pause, resume, inject messages) driven by the Northstar computer-use model, a direct computer-control
    surface (create/list/delete computers, click, type, scroll, navigate, screenshot, shell exec, tabs, batch actions), an
    OpenAI-compatible Responses API with computer-use tool calls and multi-turn previous_response_id chaining, Chat Completions,
    and a Models listing. Errors use RFC 7807 problem+json; task streams are resumable SSE.
