Use case

Competitor Price Tracking

Tracking competitor prices manually — downloading their feeds, comparing spreadsheets, spotting the changes — doesn't scale. If you have access to a competitor's product feed (through marketplaces, price comparison sites, or shared retailer feeds), Catalogian turns it into a live price monitoring system.

Add your competitor's feed as a source in Catalogian. Every time it updates, you get a precise delta showing which products changed price and by how much. Query the API for the biggest price drops, filter by product category, or let an AI agent summarize competitive pricing trends across all the feeds you monitor.

Catalogian doesn't scrape websites or violate terms of service — it works with feeds you already have legitimate access to. This makes it ideal for marketplace sellers monitoring shared category feeds, brands tracking authorized retailer pricing, or agencies managing competitive intelligence across client portfolios.
