## 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 pocket-network-headless-browser-web-renderer-6b363217 -d '<json body>'
```

Example prompt: Can you load https://example.com/dashboard in a headless browser with JavaScript enabled, wait 1000ms for it to fully render, and give me the page content as markdown and a list of all links on the page?

## When to prefer this

Choose this endpoint when the target page is a JavaScript-rendered SPA, React, Vue, or Angular app where a plain HTTP fetch would return empty or incomplete content. It is ideal when you need a rendered screenshot in addition to text, or when you need to wait for dynamic content (e.g. lazy-loaded data) using a CSS selector or a timed delay. Prefer a simpler fetch endpoint for static HTML pages where JS execution is unnecessary. Use this over a generic web search when you already know the exact URL and need the full rendered page content.

## Known failure modes

- URL is a private/internal address — refused with error
- robots.txt disallows crawling — request refused
- Page fails to load within timeout — partial or empty content returned
- wait_for_selector not found within 1.5s — timeout error
- Screenshot exceeds 1 MB limit — truncated or error
- Invalid URL scheme or port — rejected
- max_chars truncation silently caps returned content

## How this service works

Load a URL in headless Chromium with JavaScript executed and get the rendered page back for an LLM or RAG pipeline: markdown, text, HTML, title, links and an optional screenshot. POST /v1/render with {url}. Robots.txt is honored and private addresses are refused. JSON in, JSON out, errors included. Pay per request in USDC; no account, no API key.

## Output

A JSON object containing whichever output formats were requested: 'markdown' (cleaned Markdown text), 'text' (plain text), 'html' (full rendered HTML), 'links' (array of URLs found on the page), plus the page title, and optionally a base64-encoded screenshot (PNG or JPEG, up to 1 MB). Errors are included in the JSON response.
