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.
Example use cases
Validate job posting before outreach
“Check if this job posting is still open before I send out a candidate: https://jobs.example.com/posting/software-engineer-12345 — I need to know if the apply form is still there.”
Confirm eBay item still available
“Is this eBay listing still active? https://www.ebay.com/itm/3456789012 — tell me if it's sold out or still up before I try to buy it.”
Pre-scrape product page check
“Before my scraper runs, verify that https://myshop.myshopify.com/products/red-sneakers is still live and in stock, not showing a sold-out or 404 page.”
Technical details
Endpoint
POSThttps://livecheck.fly.dev/v1/verify/listing?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
