H Company

H Company (hcompany.ai) is a Paris-based AI lab, backed by Accel and Creandum, that builds the Holo family of vision-language models and a Computer-Use Agents platform for automating work on browsers and desktops. It ships two public APIs: the Computer-Use Agents API (agp, /api/v2) for launching, steering, scheduling, and observing autonomous agent sessions — with reusable agents, skills, environments, browser profiles, vaults, and signed webhooks — and the OpenAI-compatible Holo Models API (/v1) serving the Holo3 and Holo3.1 models. Typed Python and TypeScript SDKs (hai-agents), a hai CLI, an official MCP server, and idempotent, region-isolated (EU/US) REST round out an agent-native developer surface.

H Company publishes 1 API on the APIs.io network: Computer-Use Agents API. Tagged areas include Artificial Intelligence, Agents, Computer Use, Automation, and Machine Learning.

The H Company catalog on APIs.io includes 1 event-driven AsyncAPI specification.

H Company’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, pricing, signup flow, and 23 more developer resources.
