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-seller-monitoring/run-sync?token=apify_api_hJuwI*********"
payload = {
    "amazon_domain": "www.amazon.ae",
    "asins": [
        "B0BFN7LPMP",
        "B0B1575BFZ",
        "B094ZFWV42",
        "B09NSL63GZ",
        "B08R7MWYLG",
        "B098T5W2BK",
        "B07GQC7VYD",
        "B0BHYN9XK7",
        "B09PHLHS51",
        "B07KJR4VB8",
        "B07NCWBTL4",
        "B08V5CY7FR",
        "B08VJ4HPZ3",
        "B09T7249BX",
        "B0B14MF2NJ"
    ],
    "get_amazon": 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.
