I Built a Real-Time E-Commerce Price API (100 Free Calls/Day)

The Problem

Every e-commerce developer eventually faces the same wall: pricing data is locked inside marketplaces.

Scraping is fragile. Proxy services cost $500+/month. Public APIs either don’t exist or cost a fortune.

So I built PricePulse API — a simple REST API that returns structured pricing data from major e-commerce platforms.

What It Does

import requests

API_KEY = "your_key_here"
headers = {"Authorization": f"Bearer {API_KEY}"}

# Search Carousell Singapore
r = requests.get(
    "https://pricepulseapi.site/api/v1/search",
    params={"q": "iphone 15", "source": "carousell"},
    headers=headers
)
print(r.json())

Enter fullscreen mode Exit fullscreen mode

Returns clean, structured JSON:

{
  "query": "iphone 15",
  "results": [
    {
      "title": "iPhone 15 Pro Max 256GB",
      "price": "$1,299",
      "currency": "SGD",
      "url": "https://carousell.sg/...",
      "source": "carousell"
    }
  ]
}

Enter fullscreen mode Exit fullscreen mode

Python package:

from pricepulse_api import PricePulse

client = PricePulse(api_key="your_key")
results = client.search("macbook pro", source="amazon")
for item in results[:5]:
    print(f"{item['title']} — {item['price']}")

Enter fullscreen mode Exit fullscreen mode

Why Free?

Building trust takes time. I want you to test the data quality before paying a cent. If 100 calls/day covers your needs, great. If you need more, the paid plans start at $10/month.

The API has been running reliably for over a month. It’s production-ready.
