# AgentHost: Vercel for AI Agents

> You can now deploy an AI agent site with one curl command. No signup. No config. HTTPS in under a second.

Deploying something agents build should be as fast as agents build it. That's the whole idea behind [AgentHost](https://sites.rosabuilds.com).
One command. One second. Live HTTPS URL. No dashboard, no signup, no YAML config to fight with.
The Problem It Solves
AI agents can write code, generate HTML, and build entire mini-apps in seconds. But then what? You still had to SSH into a server, run a deploy script, configure a domain, wait for a build pipeline. That's a 10-minute human bottleneck at the end of a 10-second agent task.
AgentHost removes that bottleneck. An agent can generate a site and deploy it in the same run — no human in the loop required.
How It Works
You POST a .tar.gz to the deploy endpoint. You get back a URL. That's it.
curl -X POST https://sites.rosabuilds.com/deploy \
  -H "X-Api-Key: YOUR_KEY" \
  -H "Content-Type: application/octet-stream" \
  --data-binary @site.tar.gz
# → {"id":"abc123","url":"https://abc123.sites.rosabuilds.com"}
The whole flow — compression, upload, extraction, serving — takes under a second. The URL is live on HTTPS immediately. No warmup, no cache invalidation, no waiting on a CDN to propagate.
Why This Matters for Agents
The missing piece in most agent workflows isn't generation — it's deployment. Agents are great at producing artifacts. They're blocked by the fact that getting those artifacts in front of a human still requires human infrastructure work.
AgentHost is infrastructure designed for agent workflows. The API is dead simple because it has to be — agents need deterministic, low-friction endpoints. One input format. One response shape. No edge cases to handle.
Think about what becomes possible:
- An agent that generates a personalized landing page and deploys it live in one conversation turn
- A coding agent that ships a working demo URL, not just a GitHub link
- An agent that creates a report, renders it as HTML, and hands you a shareable link

None of that required a developer or a DevOps engineer. It required a curl command.
Free. Live Now.
AgentHost is free and live at [sites.rosabuilds.com](https://sites.rosabuilds.com). Get an API key, bundle your site, deploy. The whole thing works today.
If you're building agents that produce anything worth sharing — HTML, reports, tools, demos — this is the fastest path from generated to live.
