How this service works

Generate and host a webpage from HTML or Markdown content. Returns a live URL valid for 365 days. After publishing, the returned slug is reachable via free routes: `GET /s/:slug` (canonical render, increments visit counter), `HEAD /s/:slug` (head-only, no body), `GET /site/:slug` (legacy alias), `GET /stats/:slug` (JSON metadata + visit count).

Output

Returns a JSON object containing the live URL where the page is accessible, the slug identifier, the page title, the content format used, creation and expiration ISO 8601 timestamps, TTL in days (always 365), content size in bytes, and an operational note describing how to refresh the page.

Example use cases

Shareable project status page

“Take this Markdown and publish it as a hosted webpage with the slug 'team-status' and title 'Team Status Update' so I can share the link with stakeholders: '# Team Status\n\n**Sprint 12** is on track. We shipped the auth module and fixed 14 bugs.'”

Custom-styled HTML landing page

“Host this HTML as a live page for the next year — use the slug 'launch-day', title it 'Product Launch', and inject this CSS to make the background dark: 'body { background: #111; color: #eee; }'. Here's the HTML: '<h1>We launched!</h1><p>Sign up now at our link below.</p>'”

Auto-generated report page for agent output

“I just generated a Markdown report summarizing this week's sales data. Can you publish it as a webpage with the title 'Weekly Sales Report' and a random slug so I get a shareable URL I can drop into Slack?”

Technical details

Endpoint

POSThttps://site.withzero.ai/run?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need to instantly publish HTML or Markdown as a publicly accessible webpage with a stable URL that lasts up to a year, without needing your own server or CDN. Ideal when you want to share agent-generated content, reports, or landing pages via a link. Prefer it over file storage endpoints when the output must be human-readable in a browser, and over full CMS platforms when you need a lightweight, zero-setup publish with a custom slug and optional CSS styling.

Side effects

Missing or empty content field returns a validation error
Slug conflicts with a taken slug — the existing site is overwritten silently
Slug pattern violation (uppercase, special characters) returns a 400 error
Content exceeding 1MB (1,048,576 bytes) is rejected
Invalid format enum value (not 'html' or 'markdown') returns a validation error
Custom CSS exceeding 50,000 characters is rejected

Input

Schema · Request body

Field	Type	Description
css	string	Custom CSS to inject into the page. Applied after the default styles, so you can override any default styling. Example: "body { background: #000; color: #fff; }"
slug	string	Custom URL slug. Must be lowercase alphanumeric with hyphens/underscores. If not provided, a random 8-character slug is generated. If the slug already exists, the existing site is overwritten.
title	string	Page title (shown in browser tab). Defaults to "Untitled" if not provided.
format	string	Content format. "html" (default): raw HTML content. "markdown": Markdown text that gets converted to HTML with a clean, responsive default template.
contentrequired	string	The website content. Either raw HTML or Markdown text. For HTML: can be a full document (with <html>) or a fragment (just the body content). For Markdown: standard Markdown syntax (headings, bold, links, code blocks, etc.).
wrapInTemplate	boolean	Whether to wrap the content in the default HTML template with responsive styles. Set to false if your HTML content is already a complete document. For markdown, this is always true.

Reviews

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
