# Livecheck Listing Verifier

> Livecheck Listing Verifier is a paid API for AI agents from livecheck.fly.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-14).

Checks whether a specific job posting, Shopify/HTML product page, or eBay item URL is currently live, closed, or unknown, returning status signals like apply form presence, in-stock/sold-out indicators, and 404 detection.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-listing-verifier-a2187fd8 -d '<json body>'
```

Example prompt: Before you scrape that product page, check if https://www.shopify-store.com/products/blue-widget is still live and in stock — I only want to proceed if it's active.

## When to prefer this

Use this endpoint when you already have a specific listing URL (job, product, or eBay item) and need to confirm it is still active before scraping, processing, or acting on it. This is not a search engine — it only validates a URL you already possess. Prefer this over scraping directly when you want to avoid wasting resources on dead or filled listings, or when you need a lightweight status check before a heavier downstream action.

## Known failure modes

- URL is a search-results page rather than a specific listing — returns unknown or error
- URL is not reachable due to network/firewall restrictions — returns unknown
- Page uses heavy JavaScript rendering that obscures signals — may return unknown
- Malformed or non-HTTP(S) URL — returns validation error
- Anti-bot measures on the target site may block the check — returns unknown

## 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 of 'live', 'closed', or 'unknown' along with the page title and a set of signals indicating whether an apply form is present, the item is in stock, the item is sold out, or the page returned a 404 error.
