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()

Charging empty results

If a product ASIN returns 0 sellers, we charge a minimum of 1 to 5 results to cover proxies costs & infra

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.
