How teams use it
Typical ways teams put structured public-web data to work. These are illustrative scenarios, not customer case studies.
WhoWhat they doWhat they get
Retail pricing team

What they getA dated price history for each product and region, delivered to their own dashboard.
Marketplace seller
What they doWatches price and stock on competing listings so restocking and repricing use current information.
What they getEmail alerts and a record each time a listing's price or availability changes.
Market-research analyst
What they doCollects titles, SKUs, variants, and prices from public catalogs to study a whole category.
What they getOne consistent dataset instead of pages of HTML to clean up.
Data team
What they doFeeds structured product data into internal models, reports, and pricing tools.
What they getTimestamped JSON records, each tied to its source URL.
From a public page to a row in your database
Public product page
A publicly accessible listing, the same page a shopper sees.
Shield Scraper
Collected over HTTP, or in a managed browser session where the page needs one.
Structured JSON
One consistent schema, timestamped and tied to its source URL.
Your systems
Delivered to your database, dashboard, or API.
What a record looks like
Every collected record arrives as structured JSON, ready for a database, a dashboard, or an API, with no HTML to parse.

The right collection method for each source
Some workloads only need a standard HTTP request. Others need a browser to render the page. Shield Scraper supports both, so each source is collected in the simplest way that returns accurate data.
Fig. 1
Standard HTTP collection
Where a page serves its data directly, lightweight HTTP requests collect it quickly and efficiently, with no browser required.
Fig. 2
Managed browser sessions
Managed browser sessions for collecting data from modern JavaScript-rendered websites, including pages that need normal browser interaction to display their content.
Fig. 3
Geo-distributed data collection
Proxy infrastructure is used to collect from multiple regions, so prices, currencies, and availability can be compared the way local shoppers see them. Built for regional market research.
Built for teams that run on public-web data
E-commerce & retail intelligence
Retail is where structured public-web data does the most work. Shield Scraper collects from any public website, with specialty, purpose-built support for select marketplaces such as Daraz.lk.

Shield Scraper collects structured data from public websites — prices, stock status, SKUs, product titles, variants, availability, regional differences, and other product metadata — and delivers it as consistent, timestamped records.
Both. Some sources serve their data directly and are collected with standard HTTP requests. Others render data with JavaScript or need normal browser interaction, and those run in managed browser sessions. We use the simplest method that returns accurate data.
It depends on what is collected, from where, and how it is used, and the answer differs by jurisdiction. Shield Scraper is built for public-web data collection and business intelligence, and we do not claim every use case is lawful or permitted. Customers are expected to comply with applicable laws, contractual obligations, and relevant website policies. Our Acceptable Use Policy lists what is prohibited.
Shield Scraper can collect from any public website. A handful of specialty marketplaces, including Daraz.lk, get deeper, purpose-built support. If you have a specific source or use case in mind, get in touch and we will tell you honestly whether it is a fit.
We may ask customers to describe what they plan to collect and from where. It helps us set up the right controls, and it is part of how we keep the platform to legitimate use.
Email abuse@shieldscraper.com with the affected domain or URL, the approximate time, and what you observed. We review every report and can act on individual customers.
