ht-ml.app

ht-ml.app is HTML hosting with an API for agents. It is built for publishing a single HTML document and returning a public URL right away, with examples and instructions aimed at Claude Code and Codex.

The service accepts a POST request containing html_content and can return site_id, url, update_key, and status. It also supports an optional password when a site is created, and pages are public by default unless that password is set. Sites are scanned for unsafe content before they go live. For later changes, PUT /v1/sites/{site_id} replaces the HTML, and the same flow can be used to manage passwords. The API can also enumerate referenced assets such as images and video, show which ones are missing, and accept uploads for those assets using the update_key.

Delivery is centered on a JSON API at https://api.ht-ml.app/v1. The site says each published page gets its own subdomain under ht-ml.app, and relative asset paths work there. It also exposes /v1/help as a machine-readable summary, describes /llms.txt as a concise LLM-optimized reference, and says the page registers a WebMCP tool named publish_html_site for in-browser agents through navigator.modelContext or document.modelContext. The documentation also mentions an open html Agent Skill that installs with Claude Code and Codex, with alternative installation through a skills CLI, and notes compatibility with Claude Code, Codex, OpenClaw, Hermes, and other Agent Skills clients.

Access and visibility are described clearly: pages are public by default, can be made private with a password at creation, and can be crawled or indexed unless protected. Error responses are intended to be actionable for agents. The page also states that AI crawlers are explicitly welcomed in robots.txt, and that structured data is embedded for crawlers and answer engines. No pricing information is provided in the supplied material.
