## 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-5b08a433
```

Example prompt: Can you grab the full article from https://www.nytimes.com/2024/01/15/technology/ai-agents.html and give it to me as clean markdown so I can summarize it?

## When to prefer this

Use this endpoint when you need the full article body of a web page for LLM consumption, summarization, or analysis — not just metadata or a preview. Prefer over /api/url/unfurl when you need the complete article text rather than just a 500-character preview and metadata. Best suited for news articles, blog posts, and documentation pages where the main content is clearly delimited from surrounding boilerplate.

## Known failure modes

- URL is unreachable or returns non-200 status — extraction fails with error
- Response body exceeds 512KB cap — truncated or rejected
- Request times out after 8 seconds — timeout error
- URL resolves to a private/internal IP (SSRF guard) — blocked with error
- Too many redirects (>5) — redirect limit error
- Page has no identifiable article content — returns empty or minimal markdown

## How this service works

Fetch any URL and return its article content with the clutter stripped — nav, ads, sidebars, footers, scripts, styles, comments removed via heuristic extraction (<article> / <main> / role=main / densest block). Choose the output with `format`: markdown (default), text, both (JSON envelope), html (a self-contained readable reader-view page, raw text/html), or pdf (a clean typeset reading document, raw application/pdf). html/pdf are built from the same cleaned content, so they carry no live page, no third-party assets, no trackers. SSRF-guarded, 512KB body cap, 8s timeout, 5 redirects max. JSON formats return { url, finalUrl, title, markdown?, text?, wordCount, sourceBytes }. This uses a raw HTTP fetch (no JavaScript) — for client-rendered / SPA pages whose content only appears after JS runs, use /api/url/render (same formats, headless-rendered). For a pixel-perfect image of the live page use /api/ai/screenshot; to enumerate a page or sitemap into its links use /api/url/map.

## Output

Returns a JSON object with: url (original), finalUrl (after redirects), title, markdown (clean article as markdown), text (plain text, if requested), wordCount, and sourceBytes. Non-article page elements like nav, footer, ads, scripts, and comments are stripped out.
