/01 — what people use this for

three jobs we see every day.

/01 · sharesend an ai-agent-generated artifact to a teammate without zipping a folder.

/02 · previewspin up a public preview of an html email or one-pager before it ships.

/03 · hoststand up a landing page, demo, or pitch link in under a second — without a dashboard.

/02 — api

or skip the page entirely. one post, one url back — works from claude, chatgpt, your shell, your code.

mcp · claude

~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "htmlshare": {
      "url": "https://api.htmlshare.net/v1/mcp"
    }
  }
}

then ask claude: “publish this as an htmlshare link” — it just works. (restart claude desktop once after adding the config.) chatgpt works too, and an api key makes connector publishes permanent — see the docs for setup.

curl

terminal

# publish from the terminal
curl -X POST https://api.htmlshare.net/v1/publish \
  -H "content-type: application/json" \
  -d '{"html":"<!doctype html><h1>hello</h1>"}'

# → { "url": "https://htmlshare.net/p/k9m2qa42", "expiresAt": "..." }

accepts application/json (html field) or multipart/form-data with a file. 10mb max.

node.js

publish.mjs

import { readFile } from 'node:fs/promises';

const html = await readFile('./report.html', 'utf-8');
const { url } = await fetch('https://api.htmlshare.net/v1/publish', {
  method: 'POST',
  headers: { 'content-type': 'application/json' },
  body: JSON.stringify({ html }),
}).then((r) => r.json());

console.log(url); // → https://htmlshare.net/p/k9m2qa42

works anywhere with fetch — node ≥ 18, bun, deno, browsers.
