Monitor Competitor Prices
Across Any Storefront
Retail storefronts build their product pages in the browser — prices, stock and variants arrive after the initial HTML. FineData reads the page the way a browser does and returns clean product data at scale.
The E-commerce Scraping Challenge
Pricing intelligence requires real-time data from hundreds of competitor sites. But modern e-commerce platforms are designed to block exactly this kind of automated access.
Plain HTTP Clients Get Partial Pages
Retail and marketplace sites are tuned for real browsers. A bare HTTP client — no TLS profile of a real browser, no JavaScript engine — often receives an interstitial or a stripped page instead of the product.
JavaScript-Heavy Pages
Product prices, stock status, and variants are often loaded dynamically via JavaScript. Simple HTTP requests miss this data entirely.
Scale Requirements
Monitoring thousands of SKUs across dozens of competitors means tens of thousands of requests daily. Managing proxy pools and retries at this scale is a full-time job.
Regional Pricing
Prices vary by region. You need to see what customers in different countries actually pay, not just your local prices.
How FineData Solves It
A real browser with a matching TLS profile, driven by an API call. You get the complete product page — including prices, stock levels and variants that load after the HTML.
Browser-Grade Requests
Requests carry a genuine browser TLS profile and run a genuine browser engine, so a page written for humans returns the same content to you. If it still does not, the request is not billed.
JS Rendering
Enable JS rendering to capture product data loaded by React, Vue, or Angular storefronts. Wait for specific elements to load before capturing the page.
Batch Processing
Submit up to 100 product URLs in a single batch request. Monitor entire product catalogs efficiently with parallel processing.
Extract Product Data From Any Store
Hosted storefront or a custom React build, FineData renders the page and returns the complete HTML with all product data loaded.
Captures dynamically loaded prices, stock status, and reviews
No browser fleet or custom scripting to maintain on your side
Batch endpoint for monitoring thousands of products per run
import requests
# Read a JavaScript-rendered product page
response = requests.post(
"https://api.finedata.ai/api/v1/scrape",
headers={"x-api-key": "fd_your_key"},
json={
"url": "https://store.example.com/product/wireless-headphones",
"use_js_render": True,
"js_wait_for": "networkidle",
"stealth_antibot": True,
"tls_profile": "chrome124",
}
)
data = response.json()
html = data["content"]
# Parse product data from rendered HTML
from bs4 import BeautifulSoup
soup = BeautifulSoup(html, "html.parser")
price = soup.select_one("[data-price]")
stock = soup.select_one(".stock-status")
Use js_wait_for: "networkidle" to
wait for all AJAX requests to complete before returning the page content.

Frequently Asked Questions
What if a product page returns an interstitial instead of data?
stealth_antibot: true,
which runs a full browser with a matching TLS profile; for the heaviest pages there is
stealth_antibot_headful: true.
Because failed requests are not billed, trying a mode costs you nothing when it does not
work. What FineData does not do is get you access to content that is not publicly
available -- see the Acceptable Use Policy.

What this is for
Publicly available product information — prices, availability, descriptions, specifications. FineData does not sign in to accounts, does not pass paywalls, and does not reach content that a visitor could not open. You remain responsible for the terms of the sites you request and for any personal data you collect; the Acceptable Use Policy sets out both in full.
