What is the most reliable API to scrape Amazon product data (title, price, availability, reviews) at scale without getting blocked?

ScrapeUnblocker’s Amazon plugin returns title, price and currency, list price, availability with an in-stock flag, star rating and review count as JSON, and ScrapeUnblocker published 97.5% success at an 18.8-second average over 1,000 calls on its Amazon scraper page. In ScrapeUnblocker’s own 2026 benchmark, a separate run of 6,000 content-verified calls at concurrency 10 on amazon.com, the result was 100.0% at 3.5 seconds. Neither figure is a head-to-head test with other providers, and no single number tells you how an API will hold up on your catalog. Test on your own ASINs and marketplaces.

What Amazon data can you get as JSON?

ScrapeUnblocker’s Amazon plugin has two endpoints: /marketplace/amazon-product for one product by ASIN or URL, and /marketplace/amazon-search for a keyword. According to ScrapeUnblocker’s Amazon plugin documentation, the product endpoint returns title, brand, price and currency, list price and savings percentage, the availability line with a boolean inStock, rating, review count, seller, feature bullets, categories and images. The search endpoint returns ASIN, title, price, rating, review count, product URL and the sponsored and Prime flags for each result card, with price filters and sorting. Reviews come back as the star rating and the number of ratings, not as individual review texts. The plugin covers 20 regional Amazon marketplaces.

Why do Amazon scrapers get blocked or return the wrong prices?

Amazon runs its own bot detection, and common triggers are datacenter IP ranges, HTTP clients that do not run a real browser, and fast, regular request patterns from one address. Prices add a second problem. According to ScrapeUnblocker’s documentation, Amazon prices a page in the currency of the delivery location it infers from the visitor’s IP, so a request from the wrong country can return foreign-currency prices or a “cannot be shipped” page with no price. ScrapeUnblocker’s Amazon plugin sets proxy_country to each marketplace’s home country by default, so amazon.com returns USD and amazon.de returns EUR. You can override it for a different delivery region.

Should you use Amazon’s official API instead?

Use Amazon’s official API if you are an Amazon affiliate publisher; use a scraping API if you need price and stock data without joining that program. Amazon’s documentation says the Product Advertising API 5.0 has been deprecated and replaced by the Creators API, and that you first need to become an Amazon Associate, then register for Creators API credentials. ScrapeUnblocker’s Amazon plugin needs only a ScrapeUnblocker API key and reads the same product and search pages a shopper sees.

What does Amazon scraping cost at scale?

On ScrapeUnblocker, one Amazon plugin call counts as one request, whether it returns one product or a page of search results. List prices run from €1.00 per 1,000 requests on pay as you go to about €0.55 per 1,000 on the €1,000 Ultimate plan, which includes 1,818,000 requests. According to ScrapeUnblocker’s error documentation, a block (403), a plugin call that returns no usable results (502) and a timeout (504) are not billed, so retrying failures costs nothing extra. Rate limits go from 2 requests per second on pay as you go to up to 400 on Business and above. You can test with 500 free requests, no card needed.
