eCampus Textbook Price & Marketplace Vendor Scraper

Look up live textbook pricing on eCampus.com by ISBN: the retailer's list/new price, the lowest third-party marketplace price, eBook rental pricing — and a full breakdown of every individual marketplace vendor offer (seller name, rating, price, condition, quantity, shipping) for a given ISBN. Built on eCampus.com's own public bot-price data feeds, so there's no login, no cookies, and no proxy required.

What this actor does

• Three modes:
  • priceSnapshot (default) — one record per ISBN with list price, current new price, lowest marketplace price, and eBook price/duration
  • marketplaceOffers — one record per third-party seller for the ISBN (seller name, rating, price, condition, quantity, ships-from state, expedited shipping, item comments) — this is the closest thing to a multi-vendor price comparison for the title
  • ebookOffers — one record per available eBook access duration/price option
• Batch by ISBN list — pass any number of ISBN-10 / ISBN-13 strings; each is queried independently
• Filters: price range, vendor offer condition, minimum vendor rating
• Sort: order marketplace vendor offers / eBook options by price (low-to-high or high-to-low) or vendor rating (high-to-low), same as eCampus's own vendor comparison listing
• Empty fields are omitted — every record only contains data eCampus actually returned

FAQ

Do I need an account, cookies, or a proxy? No. This actor calls eCampus.com's public bot-price data feeds directly — the same feeds eCampus's robots.txt publishes for AI/search crawlers to use instead of scraping HTML pages. No login, no cookies, no proxy configuration needed.

Why isn't this a buyback/sell-price comparator? eCampus.com's robots.txt explicitly disallows crawling its dedicated /buyback/ sell-quote pages. Other textbook buyback-comparison sites (BookScouter.com, CampusBooks.com, GetTextbooks.com) were evaluated and found to gate their price pages behind Cloudflare Turnstile / proof-of-work challenges that cannot be solved without paid CAPTCHA-solving or residential proxies — both out of scope for this actor. This actor instead exposes eCampus's sanctioned, multi-vendor marketplace (buy-side) price comparison, which surfaces the same kind of "many sellers, one ISBN" data. When eCampus's own sanctioned priceSnapshot feed happens to include a buybackPrice for a title (some titles carry a same-endpoint Buyback available value), it's passed through — but there's no separate buyback crawl or lookup mode.

What if an ISBN has no current marketplace offers or isn't sold by eCampus? The ISBN is simply skipped for that mode — no error, no placeholder record. If none of your ISBNs return data, check the run's status message.

Can I look up multiple ISBNs in a single request to eCampus? No — eCampus's feed only accepts one ISBN per request. This actor loops over your isbns list and issues one lookup per ISBN, so you can still batch as many ISBNs as you like in a single actor run.

Is vendorRating always present? No — many marketplace sellers have no rating yet (too new / no ratings). Those records simply omit vendorRating and vendorRatingCount rather than showing 0 or null.

What currency are prices in? USD — eCampus.com is a US textbook retailer.

How fresh is the data? Live — every actor run queries eCampus's price feed in real time; there is no caching layer.
