Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

### 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

```python
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.

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
