FAQ

What data can you deliver?
Publicly available data from the web — catalogues, listings, directories, marketplaces — as JSON records with the fields you choose, built on request. Ready today: product data from 12 Amazon marketplaces, with title, brand, the selected variant and its siblings, price, Best Sellers Rank, rating and every label–value pair of the product-details section. A field that cannot be read is null — values are never guessed.
Where does the data come from?
From publicly available web pages. Marketplace data comes from publicly available Amazon product pages, read on demand and on a schedule for monitoring. Screaming Data is an independent service and is not affiliated with Amazon.
How is it priced?
Ready-made marketplace data has public list prices, charged per call from a prepaid balance in US dollars, and every response states its exact cost. Custom datasets are quoted per project; volume terms are available. See pricing.
How do I get access?
Request access with a few lines about the data you need and your expected volume. Our data team scopes every request and replies with a written proposal. Once your account is set up, you receive a secure one-time link to your API login and first key — keys are never sent in plain e-mail.
