Stop Overpaying Online: How I Built a Real-Time Price API That Saves You Money

#api #webdev #python #opensource

Ever bought something online, only to find it cheaper on another platform the next day? Yeah, me too.

That frustration is exactly why I built PricePulse — a simple, fast API that fetches real-time prices from major e-commerce platforms (Amazon, eBay, Carousell, and more).

What Is PricePulse?

PricePulse is a REST API that returns current market prices for any product. Point it at a product URL or search term, and it returns structured JSON with price, currency, platform, and more.

No scraping setup. No browser automation. No proxy management headaches. Just one API call.

Quick Start (30 Seconds)

# Get product price by URL
curl -X GET "https://pricepulseapi.site/api/v1/price?url=https://www.amazon.com/dp/B0B8V35XQQ"

# Search for products
curl -X GET "https://pricepulseapi.site/api/v1/search?q=iPhone+15&source=amazon"

Response:

{
  "product_name": "iPhone 15",
  "price": 799.00,
  "currency": "USD",
  "platform": "amazon",
  "in_stock": true,
  "url": "https://www.amazon.com/dp/B0B8V35XQQ"
}

What You Can Build

Price drop alerts — Get notified when prices fall below your threshold
Competitive analysis — Track competitors' pricing automatically
Arbitrage tools — Spot price differences across platforms instantly
Shopping assistants — Build a chatbot that finds the best deals
Price history tracking — Monitor trends over time

Pricing (Fair and Simple)

Plan	Price	Calls/Day
Free	$0	100
Starter	$10/month	5,000
Pro	$50/month	25,000

No credit card required to start. The free tier gives you 100 calls/day — enough to build a prototype or run personal price checks.

Why I Built This

I was tired of the over-engineered "solutions" out there. Most price APIs charge an arm and a leg or force you into annual contracts. PricePulse is designed to be straightforward:

Simple REST API — Works with any programming language
Fast response times — Results in seconds, not minutes
Multiple platforms — Amazon, eBay, Carousell, and growing
No hidden fees — What you see is what you pay
Free tier — Because everyone deserves access to price data

Python SDK (pip install)

pip install pricepulse

from pricepulse import PricePulse

client = PricePulse(api_key="your_key")
result = client.get_price("https://www.amazon.com/dp/B0B8V35XQQ")
print(f"Price: ${result.price}")
