# 402utils Link Preview / Meta Extractor

> 402utils Link Preview / Meta Extractor is a paid API for AI agents from 402utils.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-11).

Fetches a URL's <head> and returns structured metadata: title, description, canonical URL, language, favicon, Open Graph tags, Twitter Card tags, and feed links — no JS execution, SSRF-safe.

## 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 402utils-link-preview-meta-extractor-f840175d
```

Example prompt: Can you pull the link preview metadata for https://stripe.com — I need the page title, meta description, og:image, favicon URL, and any RSS feeds it exposes?

## When to prefer this

Use this endpoint when you need fast, lightweight extraction of webpage metadata (title, description, OG tags, Twitter Card, feeds, favicon) from a URL without full browser rendering. Ideal for link unfurlers, content enrichment pipelines, social preview generation, and feed discovery. Prefer it over full-page scrapers when you only need <head> data and want SSRF safety and size/time limits built in.

## Known failure modes

- SSRF check blocks private/internal IP URLs — returns an error without fetching
- Page exceeds 5 MB response body cap — fetch is truncated or rejected
- Fetch times out after 8 seconds — returns a timeout error
- Malformed or unreachable URL — returns a network or DNS error
- Non-UTF-8 charset pages may have imperfect text decoding but are tolerated best-effort
- Pages requiring JavaScript rendering will return empty or minimal metadata since no JS is executed

## How this service works

Link preview for any web page: fetches a URL and parses only the <head> (no JS, no rendering). Returns title, meta description, canonical URL, language, an always-absolute favicon, all Open Graph and Twitter Card tags, and RSS/Atom/JSON-feed links. Tolerant of messy real-world HTML and non-UTF-8 charsets. The caller-supplied URL is SSRF-checked; the fetch is capped at 5 MB and 8 s.

## Output

A JSON object containing: the requested URL, the final URL after redirects, the page title (entity-decoded, whitespace-collapsed), meta description, canonical URL, HTML lang attribute, an always-absolute favicon URL, all og:* tags (prefix stripped), all twitter:* tags (prefix stripped), and an array of RSS/Atom/JSON feed links with their type and title.
