Track price, stock and page changes on any public product page you list: Shopify, WooCommerce, Magento or custom storefronts. Reads JSON-LD, itemprop and your own CSS selectors, then returns title, price, currency, availability, SKU and a content hash per URL. Up to 50 URLs a run.

Find newsletter advertising leads: scan Substack newsletters and get one row per sponsor, with advertiser name and domain, how many times they appeared, in which newsletters, when first and last seen, and a sample of the ad text. Other scrapers give you the posts; this one gives you the buyers.

Return only never-before-seen rows from repeated Apify datasets and stop duplicate alerts, CRM records, and downstream automation actions.

Check up to 50 Apify Actors and find the ones that are quietly broken: no recent run, a failed or aborted run, a failure rate above your threshold, a successful run with an empty dataset, or output missing a required field. One health row per Actor, plus a summary.

Run an email authentication check on up to 100 domains at once. Reads public DNS for DMARC, SPF, MX and the DKIM selectors you name, parses the p, sp and RFC 9989 np policies, and returns a 0-100 score per domain with the raw records and the anti-spoofing fixes to apply first.

Trace every hop for up to 100 URLs in one run. This redirect chain checker follows 301, 302, 303, 307 and 308 responses, flags redirect loops, 4xx and 5xx destinations and chains longer than one hop, then returns each full chain with status codes, Location targets and per-hop response times.
