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 10 API contracts indexed on the APIs.io network, including Agents API, Browser Profiles API, Environments API, and 7 more. 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 26 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/h-company: open an issue to ask a question, or submit a pull request to add artifacts.

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
