PricePulse: Real-Time Price Search API for Carousell & Amazon SG - 100 Free Requests/Day

Manually checking prices across Carousell, Amazon, and other marketplaces is a pain. Wouldn't it be great if there was a simple API that searches product prices across multiple platforms with a single request?

That's exactly what I built: PricePulse API - and it's live and ready to use.

What is PricePulse?

PricePulse is a lightweight, RESTful API that aggregates real-time product listings and prices from Carousell Singapore and Amazon Singapore through one unified endpoint.

Send a search query, and PricePulse returns structured JSON with titles, prices, images, URLs, and platform info - ready to power your app, website, or e-commerce tool.

Quick Example 

GET https://pricepulseapi.site/api/v1/search?q=iphone+15&limit=5&api_key=YOUR_KEY
Enter fullscreen mode Exit fullscreen mode

Returns:

{
  "results": [
    {
      "title": "iPhone 15 Pro Max 256GB",
      "price": 1298,
      "currency": "SGD",
      "platform": "carousell",
      "url": "...",
      "image": "..."
    }
  ]
}
Enter fullscreen mode Exit fullscreen mode

Pricing (Developer-Friendly)
