## 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 skim-js-rendered-reader-822f38ad -d '<json body>'
```

Example prompt: Can you fetch and read the content from https://example.com/dashboard — it's a React SPA so a normal fetch won't work, and give me the page as clean markdown?

## When to prefer this

Choose this endpoint over the standard clean reader when the target URL is a Single Page Application (SPA), uses a JS framework like React, Vue, Next.js, or Angular, or gates its content behind JavaScript execution. If a plain HTTP fetch returns a blank page, a loading spinner, or minimal HTML shell, this JS-rendered endpoint is the correct choice. It is slower and costs the same $0.005 but ensures full content fidelity for dynamic pages.

## Known failure modes

- URL is unreachable or returns a network error
- Page requires authentication that cannot be satisfied by the headless browser
- JavaScript execution times out for extremely complex or slow-loading SPAs
- Anti-bot protections (beyond Cloudflare) block the headless render
- URL points to a non-HTML resource (PDF, image, binary file)
- Page content is behind a hard paywall requiring user credentials

## How this service works

Skim: JS-rendered reader — full browser render via Cloudflare for SPAs and JS-gated pages, clean markdown ~4x smaller than raw HTML

## Output

Clean markdown representation of the fully JS-rendered page content, approximately 4x smaller than raw HTML, along with any available page metadata. The content reflects what a real browser would see after JavaScript execution, including dynamically loaded text, components, and data.
