## 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 400860-stealth-web-scraper-4afd1b6d -d '<json body>'
```

Example prompt: Can you scrape the content from https://example.com/pricing and extract just the text inside the '.pricing-table' section, keeping it under 5000 characters?

## When to prefer this

Use this endpoint when you need to fetch content from websites that may employ bot-detection or access restrictions, and when you want to extract a specific DOM element via CSS selector rather than the full page. It is preferable to generic HTTP fetch when stealth bypassing is needed, and over full-site crawlers when you only need a single URL's content. Best suited for one-off page fetches rather than bulk crawling.

## Known failure modes

- Target URL is unreachable or returns a non-200 status
- Anti-bot or CAPTCHA protection blocks the stealth scraper
- CSS selector matches nothing on the page, returning empty content
- URL is malformed or missing, causing a 400 validation error
- Payment not authorized via x402 protocol, returning 402 Payment Required
- Rate limits or IP blocks on the target site cause partial or failed retrieval
- maxLength set too low, truncating content before meaningful data is captured

## How this service works

x402-native paid API tools for DeFi yields, protocol TVL, AI pricing, paid MCP calls, and web scraping.

## Output

The response is flexible (additionalProperties: true) and may include the raw text, structured data, or metadata about the scraped page.
