FAQs

Q: Can I scrape multiple product categories at once? Yes — simply provide multiple listing URLs or keyword sets. The scraper processes them in parallel and merges all results.

Q: What happens if both price filters are set to 0? A value of 0 for both minPrice and maxPrice removes all price restrictions, allowing the scraper to collect products from every price range.

Q: Is pagination required? No. If startPageNumber and finalPageNumber are set to 0, the scraper automatically crawls the full available pagination depth.

Q: Does it detect out-of-stock products? Yes — the output includes a boolean isAvailable that indicates real-time product availability status.
