> Livecheck URL Status Verifier is a paid API for AI agents from livecheck.fly.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Fetches a job or product page URL and returns whether it is live, closed, or unknown, along with the page title and detection signals like apply forms, sold-out indicators, and 404s.

## 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 livecheck-url-status-verifier-28803304 -d '<json body>'
```

Example prompt: Before we scrape this job listing, can you check if https://jobs.example.com/software-engineer-42 is still live and has an active apply form?

## When to prefer this

Use this endpoint when you need a fast, cheap pre-flight check on a specific job or product page URL before investing time or cost in scraping or processing it. Prefer it over a general scraper when you only need live/closed/unknown status and basic signals rather than full page content. Ideal for filtering dead links, detecting sold-out products, or confirming job postings are still open in a pipeline before downstream enrichment.

## Known failure modes

- URL is behind a login/paywall, returning unknown status
- Cloudflare or bot-protection blocks the fetch, yielding unknown
- Malformed or non-absolute URL returns a validation error
- Network timeout on slow or unresponsive target server
- Search-results or index URLs passed instead of specific item pages may yield misleading signals

## How this service works

Before you scrape a job posting, Shopify or HTML product page, or eBay item, POST the specific URL you already have and Livecheck returns live, closed, or unknown plus title and signals (apply form, in-stock, sold-out, 404); not a search engine.

## Output

Returns a status classification of 'live', 'closed', or 'unknown' for the given URL, along with the page title and a set of signals detected on the page such as presence of an apply form, sold-out indicators, or a 404 HTTP response — giving the agent enough context to decide whether to proceed with further processing.
