Build a Price Tracker in 10 Lines of Code with PricePulse U0001F680

Ever needed to check product prices across e-commerce platforms for market research, dropshipping, or arbitrage?

Manually browsing Shopee, Lazada, Amazon, eBay and Carousell is a nightmare. What if you could query them all with a single API call?

That’s exactly what PricePulse does.

What is PricePulse?

PricePulse is a real-time e-commerce price aggregation API that covers multiple platforms in one unified endpoint.

Current sources:

  • Shopee (Singapore & Indonesia)
  • Lazada
  • Amazon (SG & US)
  • eBay (US)
  • Carousell (Singapore)
  • AliExpress

You send a product name, it returns live prices, platform, currency, and product URLs — all in JSON.

Quickstart (10 Lines of Python) 

import requests

BASE_URL = "https://pricepulseapi.site/api/search"
headers = {"x-api-key": "YOUR_API_KEY"}
params = {"query": "iPhone 16 Pro", "source": "shopee"}

resp = requests.get(BASE_URL, headers=headers, params=params)
data = resp.json()

for item in data.get("results", [])[:5]:
    print(f"{item['title'][:50]}... → ${item['price']} ({item['platform']})")
Enter fullscreen mode Exit fullscreen mode

That’s it. Real product prices from real stores, in seconds.

Pricing (Fair & Simple)

Plan Price Daily Calls
Free U0001F193 $0 100/day
Starter U0001F680 $10/month 5,000/day
Pro ⚡ $50/month 30,000/day

No credit card required to start. The Free tier is genuinely usable for personal projects, research, and prototyping.

Why I Built This

I needed to track e-commerce prices in Singapore and Southeast Asia for an arbitrage project. Every existing solution was either:

  • Too expensive (enterprise scraping services charging $500+/month)
  • Too fragile (DIY scraping that breaks weekly)
  • Too limited (only covering 1–2 platforms)

So I built PricePulse to solve all three. One stable API, growing coverage, and a free tier that actually works.
