## 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 stableflare-browser-links-extractor-5d31105b -d '<json body>'
```

Example prompt: Can you render https://news.ycombinator.com in a headless browser and extract all the links from the page? Wait until the network is idle before pulling them.

## When to prefer this

Use this endpoint when you need to extract links from pages that rely on JavaScript rendering, single-page applications, or dynamic content that a simple HTTP GET cannot capture. Prefer this over static HTML parsers when the target page loads links via client-side rendering. The pay-per-request model ($0.02 USDC via x402) is ideal for agents that need occasional on-demand link extraction without managing API subscriptions.

## Known failure modes

- URL is unreachable or returns a non-2xx status — rendering fails or returns empty links
- Page never reaches the specified waitUntil state (e.g. networkidle0 timeout) — request times out
- Invalid CSS selector in waitForSelector — selector error returned
- Authentication credentials rejected by target site — page renders login wall instead of content
- HTML/URL not provided — missing required input error
- Payment not provided or insufficient — x402 payment required error

## How this service works

Extract all links from any URL. Optionally filter to visible-only or same-domain links.

## Output

A list of links (URLs/hrefs) extracted from the fully rendered page after JavaScript execution, pulled via Cloudflare's headless Chromium browser.
