Amazon Product Availability Scraper

Amazon Product In-Stock Availability Scraper

The Amazon Product In-Stock Availability Scraper is a specialized, lightweight monitoring tool designed for real-time inventory tracking.

Unlike heavy-duty scrapers that pull entire product pages, this actor is optimized for speed and accuracy, focusing specifically on whether a product is available for purchase and at what price.

It is particularly effective for high-velocity retail environments where stock status changes by the minute.

✨ Features

Buy Box vs. All Offers: Granular control to check only the "Featured Offer" (Buy Box) or broaden the search to include "All Buying Options" (third-party sellers).

Cross-Region Support: Works across all major Amazon domains (e.g., .com, .de, .co.uk, .co.jp).

Price Extraction: Captures the current active price associated with the available stock.

Buy Box Visibility Detection: Identifies if a product is technically in stock but hidden behind the "See All Buying Options" button.

Anti-Bot Resilience: Automatically handles Amazon’s anti-scraping measures to ensure high success rates for ASIN lookups.

High-Speed Batching: Designed to check hundreds of ASINs in parallel for rapid inventory snapshots.

🚀 Use Cases

Inventory Heartbeat: Plug this into a monitoring dashboard to get alerted the second a high-demand item (like a GPU or limited edition sneaker) returns to stock.

Scalping & Resale Defense: Brands can monitor their listings to ensure the Buy Box hasn't been lost to unauthorized resellers or gone "Out of Stock" due to supply chain issues.

Competitive Pricing Strategy: Track the price fluctuations of competitors' stock availability to trigger automatic repricing rules.

Affiliate Link Maintenance: Periodically scan your affiliate link library to disable or redirect traffic from products that are currently unavailable, maximizing your conversion rate.

"Back in Stock" Notifications: Power a customer-facing notification service that emails users exactly when an item becomes purchasable again.

HOW TO RUN via API

On the actor page, go to API > API Endpoints

Copy the url under "Run Actor synchronously and get a key-value store record"

Use the copied url in a request POST and provide as json the same parameters as the apify interface

Python code example

url = "https://api.apify.com/v2/acts/saswave~amazon-product-in-stock-availability-scraper/run-sync?token=apify_api_hJuwI*********"
payload = {
    "amazon_domain": "www.amazon.ae",
    "asins": [
        "B0BFN7LPMP",
        "B0B1575BFZ",
        "B094ZFWV42",
        "B09NSL63GZ",
        "B08R7MWYLG",
        "B098T5W2BK",
        "B07GQC7VYD",

    ],
    "use_apify_dataset": True
}
res = requests.post(url, json=payload)
results = res.json()

HOW MANY CONCURRENT RUNS CAN I DO

⚡ Scalability & Concurrent Runs

Your run capacity depends on your Apify plan.

Example with 32GB RAM:

Each run consumes 128MB

32GB / 128MB ≈ 256 concurrent runs

Each run processes up to 30 ASINs

Each run completes in ~5–10 seconds

⏱️ Throughput: 256 × 30 = 7,680 ASINs every ~10 seconds

That’s ≈ 768 ASINs/second, ideal for continuous seller monitoring or repricing engines.

🚀 Start Monitoring Amazon Sellers at Scale

Extract every seller on any ASIN, track Buy Box changes, monitor pricing shifts, detect new sellers, and automate Amazon intelligence workflows.
