# 2s.io Headless Browser URL Renderer

> 2s.io Headless Browser URL Renderer is a paid API for AI agents from 2s.io, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-15, last successful call 2026-07-14).

Renders a URL in a real headless browser (with JavaScript execution) and returns cleaned article content stripped of clutter, for client-rendered/SPA pages that require JS to produce content.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability 2s-io-headless-browser-url-renderer-3f6bad3f
```

Example prompt: Fetch the article content from https://example.com/some-react-app-page — it's a client-rendered SPA so you'll need to run JavaScript to get the actual content; return it as markdown and wait until the network is idle.

## When to prefer this

Use this endpoint when the target page is a client-rendered single-page application (React, Vue, Angular, Next.js CSR, etc.) whose content only appears after JavaScript executes — meaning a raw HTTP fetch returns an empty or skeletal HTML shell. If the page is server-rendered and returns full HTML content on initial fetch, use /api/url/clean instead, which is ~10x cheaper (Tier 0). Reserve this endpoint for JS-rendering cases only due to its higher cost and latency.

## Known failure modes

- Timeout exceeded (timeoutMs limit reached before JS settles — try increasing timeoutMs or switching waitUntil strategy)
- Invalid or unreachable URL returns an error
- Page has no extractable article content (returns empty or minimal content)
- Bot detection or anti-scraping measures on the target site block rendering
- Page requires authentication and content is behind a login wall

## How this service works

Render a URL in a real headless browser (JavaScript executed) and return its article content with the clutter stripped — same cleaning + output formats as /api/url/clean, but for client-rendered / SPA pages whose content only appears after JS runs (where a raw HTTP fetch returns an empty shell). `format`: markdown (default), text, both (JSON envelope), html (self-contained reader page, raw text/html), or pdf (typeset reading doc, raw application/pdf). Optional `waitUntil` (load|domcontentloaded|networkidle0|networkidle2, default networkidle2) and `timeoutMs` (1000-15000, default 12000) control how long to let JS settle. Use /api/url/clean instead for server-rendered pages — it is faster and cheaper; only reach for render when JS rendering is required.

## Output

Returns cleaned, clutter-free article content from the rendered page in the requested format: markdown (default), plain text, a JSON envelope with both, a self-contained HTML reader page (text/html), or a typeset PDF (application/pdf). JavaScript is fully executed before content is extracted.
