Proxy vs API
to scrape eBay.

Weigh the cost of maintaining a large proxy list against using eBay’s API for listings, prices, seller details and sold-item history. Some use cases need residential proxies, since datacenter IPs are more likely to be flagged on high-value listing pages.

Depending on volume, proxies can be cheaper than eBay’s developer API, but you take on the work of buying, rotating and replacing them.

Data from scraping eBay is not the same as data from the eBay API, and it is unlikely to ever be. A few reasons:

• The API exposes only what eBay chooses to expose.
• Scraping captures what a real buyer sees on the listing page, including details the API omits.
• Scraping quality varies with your scraper, so a weak one may miss fields the API would include.
• The API is consistent, which helps keep your pipeline running.

eBay runs regional sites, so request each one with the right geolocated proxy. Why it matters:

• Results differ by region. eBay.com from a European IP returns different listings, currency and shipping than a United States IP.
• Some promotions and delivery options appear only on certain regional sites, so the right proxy improves coverage.
• Requesting a regional site from an unusual location makes a CAPTCHA or error page more likely.

At Crawlbase we make accessing eBay data a simple GET request to our API. One endpoint, no extra steps.

The main benefits of our API vs the eBay API vs a proxy list:

• An easy interface to any website, including eBay.
• Geolocate your traffic to any eBay regional site.
• Receive raw HTML or scraped, structured data.
• No proxy lists to maintain.
• No CAPTCHA pages or banned IPs to worry about.
• Render listings that need a real browser with JavaScript.
• Scale to any volume your project needs.
