Free API Monitoring ??PricePulse Tracks Any Price, Anytime

rock2089 — Sat, 25 Jul 2026 02:04:33 +0000

Tired of checking competitor prices manually? Too broke for expensive scraping tools? Meet PricePulse ??a dead-simple price monitoring API that works out of the box.

What Is PricePulse?

PricePulse is a REST API that monitors any public-facing price or numeric value you care about. You define a target (product page, commodity, crypto pair, whatever), and PricePulse polls it on a schedule, stores the history, and surfaces changes through a clean dashboard and webhook alerts.

No browser to maintain. No proxies to configure. No ML training. Just results.

Why I Built It

I got tired of:

Writing scrapers that break after every site redesign
Paying $200+/month for enterprise monitoring tools when all I needed was a price
Missing price drops on things I wanted to buy

So I built the thing I wished existed. It's been running in production since early 2026.

Features That Actually Matter

?? Smart Monitoring

100 free requests/day ??enough for a side project or personal use
Desktop notifications via browser push
Configurable polling intervals
Automatic retries with exponential backoff

?? Clean Dashboard

Visual price history charts (time-series)
Price change alerts at a glance
Filter, sort, search your monitored items
Works on mobile too

?? Real-Time Alerts

Webhook notifications when prices cross your thresholds
Customizable alert conditions (above, below, percentage change)
Low latency ??alerts fire within seconds of detection

?? Pricing That Makes Sense

Plan	Price	Daily Requests	Best For
Free	$0	100	Personal projects, trying it out
Starter	$10/mo	10,000	Freelancers, small shops
Pro	$50/mo	100,000	Agencies, production apps

No hidden fees. No long-term contracts. Cancel anytime.

Quick Start

Ping a price:

curl -X POST https://pricepulseapi.site/api/monitor \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com/product", "selector": ".price", "threshold": 29.99}'

That's it. The API returns a monitor ID, starts polling immediately, and fires a webhook when your threshold is hit.

Who Is This For?

E-commerce sellers tracking competitor pricing
Deal hunters wanting instant price-drop alerts
Developers who need pricing data for their apps
Freelancers building price-aware solutions for clients
Anyone who wants to stop manually refreshing a browser tab

Try It Right Now

https://pricepulseapi.site

No credit card required. Free tier ships with 100 daily requests. If it doesn't work for you, you've lost nothing but a few minutes.

If it does work ??well, you just saved yourself a lot of pointless browser refreshing.

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?

Response:

{
  "product_name": "iPhone 15",
  "price": 799.00,
  "currency": "USD",

Build a Price Tracker in 10 Lines of Code — Free API, 100 Calls/Day

rock2089 — Thu, 16 Jul 2026 02:12:23 +0000

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']})")

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.
