## 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 otto-ai-web-links-extractor-771259cc
```

Example prompt: Can you extract all the hyperlinks from https://example.com and give me the full list of URLs found on that page?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call extraction of all hyperlinks from a single public webpage without running your own scraper infrastructure. Ideal for lightweight link discovery tasks where you want structured JSON output including freshness metadata.

## Known failure modes

- Invalid or non-public URL returns an error or empty result
- URL behind authentication or paywall cannot be fetched
- Timeout if the target page is slow to respond
- Non-HTML responses (e.g. PDFs, images) may yield no links
- Rate limiting or blocking by the target server may cause degraded mode

## How this service works

Extract all links (hrefs) from any web page as structured JSON — every internal, external and anchor link, deduplicated, returned with a total count. Renders the page in a real headless browser, so it captures links injected after JavaScript runs that fetch-only scrapers miss. For crawling, sitemap building, link audits and site-structure mapping. Keyless, pay-per-call.

## Output

Returns a JSON object containing the source URL, total count of links found, an array of all extracted hyperlink URLs, and a generatedAt timestamp. Also includes metadata about data freshness (validUntil, stalenessSec, degraded flag).
