When evaluating Amazon APIs, developers and businesses often focus on data accuracy and the breadth of features. However, one of the most critical, yet frequently overlooked, metrics is speed. The response time of an API can directly impact your ability to conduct real-time analysis, react to market changes, and ultimately, your bottom line.
To demonstrate the importance of speed, we conducted a benchmark test comparing EasyParser against two well-known competitors in the Amazon data space. The goal was simple: measure the average response time for a standard, single-product data request.
The Benchmark: Single Product Request Speed
We requested the same product ASIN from EasyParser, Competitor A (a specialized Amazon API), and Competitor B (a general web scraping API) one hundred times and calculated the average response time. The results speak for themselves.

EasyParser averaged 7.5 seconds per request, while Competitor A took 15 seconds and Competitor B required 18 seconds. This means EasyParser is 2x faster than Competitor A and 2.4x faster than Competitor B. While these differences might seem modest for single requests, they become monumental when scaling up operations.
The Scaling Problem: Where Speed Becomes a Bottleneck
Imagine you need to retrieve data for 1,000 products. If you're using an API that only allows single, synchronous requests, the math is simple and brutal:
- Competitor A (15s/request): 15,000 seconds = 4.2 hours
- Competitor B (18s/request): 18,000 seconds = 5 hours
This is where EasyParser's architecture provides a compounding advantage. Not only is our single-request API faster, but our Bulk API is designed specifically for this type of large-scale task.

By using the EasyParser Bulk API, you can submit all 1,000 requests in a single, asynchronous job. Our system processes them in parallel, and you get a webhook notification when the data is ready. The entire process for 1,000 products? Approximately 2 minutes.
This isn't just an incremental improvement; it's a fundamental shift in how you can approach data collection. What takes competitors over an hour, EasyParser can accomplish in the time it takes to make a cup of coffee.
Why Does API Speed Matter for Your Business?
The performance difference has significant real-world consequences:
- Real-Time Competitive Analysis: In a dynamic marketplace, you need to know what your competitors are doing right now, not an hour ago. Faster data means you can react to their pricing changes instantly.
- Dynamic Pricing Engines: If you're running an automated pricing strategy, your engine is only as good as the data it receives. Slow data leads to slow reactions and lost revenue.
- Reduced Infrastructure Costs: Faster APIs mean your systems aren't tied up waiting for responses. This leads to lower resource utilization and reduced server costs.
- Enhanced User Experience: If you're displaying Amazon data in a customer-facing application, a faster API means a snappier, more responsive user experience.
Conclusion: Speed is a Feature
The results of our comparison are clear. While many APIs can deliver data, only a few can deliver it with the speed necessary for modern e-commerce. EasyParser has been engineered from the ground up for performance, combining a faster single-request API with a powerful Bulk API to handle any scale.
