## Pricing

from $4.76 / 1,000 product rows

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
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`).

# README

## Amazon Product, Price, and Stock Tracker

Give ASINs or product URLs on 9 Amazon marketplaces. You get one flat row per product with the buy box price, list price, stock, seller, and rating, read for that marketplace's own delivery country. Run it on a schedule and it adds a free change row each time a price moves or a product goes out of or back into stock. Mamba Labs pays the platform costs.

### Features

- **Price for the country you sell in.** Amazon prices for the delivery country. A page seen from abroad can show a different price (we measured EUR 87.13 against EUR 74.35 on amazon.de, and GBP 10.89 against GBP 13.07 on amazon.co.uk), so a page priced for another country is refused and read again. Every row says which delivery location the page was priced for.
- **Only the buy box price.** Product pages carry other products' prices in carousels. The price comes from the buy box only. No featured offer means no price and `stock_status` `no_buy_box`, not a guess.
- **Change rows.** Change rows report `price_up`, `price_down`, `out_of_stock`, and `back_in_stock`, with the previous value and the percent. They are free.
- **Blocks are free.** If Amazon refuses every attempt for a product, you get a free `blocked` row and pay nothing for that product.
- **Cost guards.** A maximum charge per run, and the actor stops cleanly before its timeout.

### How the data is read

The actor reads Amazon's public mobile product page, the page a phone browser opens, through the Apify proxy. amazon.com and amazon.ca use the Apify proxy pool with residential addresses as the fallback. The other marketplaces use residential addresses in that country. No Amazon account, no login, no key, and no other developer's actor. Requests are retried on a new address when Amazon answers with a captcha page.

### Input

| Field | Type | Default | What it does |
|---|---|---|---|
| `products` | array |  | ASINs or Amazon product URLs, up to 1,000 per run. A URL uses the marketplace in the URL; a bare ASIN uses the Marketplace setting. |
| `marketplace` | string | `amazon.com` | The store a bare ASIN is read from. |
| `track_changes` | string | `true` | true (default) or false. With true, the actor keeps each product's last reading in a key value store in your account, and a later run writes a change row when the price moves or the product goes out of or back into stock. |
| `state_key` | string |  | Optional name for the set of last readings, when you keep several separate tracking lists. Letters, numbers, dots, dashes, underscores. |
| `previous_snapshot` | array |  | Optional. Rows from an earlier run of this actor, as a JSON list. When given, changes are computed against these rows, not the stored readings. |
| `max_charge_usd` | string |  | Optional. The run stops before a charge that would pass this amount. Summary rows are always returned. |
| `proxy_mode` | string | `auto` | auto (default): amazon.com and amazon.ca are read through the Apify proxy pool with residential as the fallback; other marketplaces use residential addresses in that country, because Amazon prices for the delivery country. residential: every product uses residential addresses in its marketplace country and is billed as product-row-local. |

Give at least one ASIN or URL. Up to 1,000 products per run. A value that is neither an ASIN nor a product URL on a supported marketplace gets its own free row and the rest still run.

### Output

| Field | Type | What it holds |
|---|---|---|
| `row_type` | string | One of: product, change, run_summary. run_summary is the one free row written when the input is refused. |
| `input` | string | The ASIN or URL you gave. |
| `marketplace` | string | The Amazon store read. |
| `asin` | string | The product's Amazon ID. |
| `asin_on_page` | string | Set only when Amazon showed a different ASIN than you asked for, such as a variation. |
| `product_url` | string | Link to the product. |
| `title` | string | Product title. |
| `brand` | string | The brand line on the page. |
| `price` | number | The buy box price as a number. Empty when the product is out of stock or has no featured offer. |
| `list_price` | number | The struck through list price, when the page shows one. |
| `currency` | string | Currency code of the marketplace. |
| `price_text` | string | The price exactly as the page shows it. |
| `stock_status` | string | in_stock, low_stock, out_of_stock, preorder, other (see stock_text), or no_buy_box. |
| `stock_text` | string | The availability message on the page. |
| `stock_left` | integer | The number when the page says Only N left in stock. |
| `seller` | string | Who sells the buy box offer. |
| `ships_from` | string | Who ships the buy box offer. |
| `rating` | number | Average rating out of 5. |
| `review_count` | integer | Number of ratings. |
| `image_url` | string | Main product image. |
| `delivery_location` | string | The delivery location Amazon priced this page for. Prices and stock can differ by location. |
| `change_type` | string | Change rows: price_up, price_down, out_of_stock, or back_in_stock. |
| `previous_price` | number | Change rows: the last price read. |
| `previous_stock_status` | string | Change rows: the last stock status read. |
| `change_pct` | number | Price change rows: percent change from the previous price. |
| `route` | string | Which proxy route read the page. |
| `attempts` | integer | Fetch attempts for this product, refused ones included. |
| `row_status` | string | ok, or why this row carries no data: no_results, no_change, partial, blocked, or error. |
| `error_reason` | string | Why the row is not ok. A refused input reads input_invalid: followed by what to fix. |
| `billable_events_json` | string | What this row was billed as, for example {"product-row":1}. {} means free. |
| `scraped_at` | string | When the row was written, UTC. |

### Pricing

Pay per event. You pay for each product page read, and for the run start. Change rows, blocked products, missing products, unreadable pages, and a refused input are free.

| Event | Free plan | Bronze | Silver | Gold |
|---|---|---|---|---|
| `product-row`, one product from amazon.com or amazon.ca | $0.0056 | $0.00532 | $0.00504 | $0.00476 |
| `product-row-local`, one product from any other marketplace, or with Proxy mode residential | $0.015 | $0.01425 | $0.0135 | $0.01275 |
| `apify-actor-start`, once per run (one per GB of memory; the default 256 MB is one) | $0.002 | $0.002 | $0.002 | $0.002 |

Per 1,000 rows of `product-row`: $5.60 on the free plan, $4.76 on Gold.

Free plan cap: 1.50 USD of evaluation a month, about 268 rows. Any paid Apify plan removes the cap, and it resets on the 1st. The run stops before a charge that passes your maximum charge per run in Apify or your `max_charge_usd` input.

Mamba Labs pays the platform costs of your run, Apify proxy traffic included.

The second price exists because other marketplaces are read through residential addresses, which cost more than the proxy pool, so those rows cost more than most Amazon actors in the Store.

### Usage examples

**A daily price and stock watch.** Schedule this; the second run on will add change rows.

```json
{
  "products": ["B00MNV8E0C", "B00FLYWNYQ"],
  "marketplace": "amazon.com",
  "state_key": "my-watchlist"
}
```

**Another marketplace, by URL.**

```json
{
  "products": ["https://www.amazon.de/dp/B01N5IB20Q"]
}
```

Read the rows with `GET https://api.apify.com/v2/datasets/{datasetId}/items`.

**Clay.** Number and on or off inputs are text fields, which is what Clay sends. A list input takes a JSON list, so put the column inside a one item list. To compute changes inside a table with no stored state, pass the earlier rows as `previous_snapshot`.

**MCP.** The Mamba Labs MCP server `@mambalabsdev/mcp-amazon-product-price-stock-tracker` exposes this actor to Claude and other MCP clients.

### Error handling

| Case | What you get |
|---|---|
| Missing or unreadable input | One free row, `row_type` `run_summary`, `error_reason` starting `input_invalid:` with what to fix. The run ends successfully and charges nothing but the run start |
| Amazon refuses every attempt for a product | A free row, `row_status` `blocked`, with the attempts count |
| The ASIN has no page on that marketplace | A free row, `row_status` `no_results` |
| A listing with no featured offer | A charged row with `stock_status` `no_buy_box`, an empty price, and title and rating. This also covers a parent listing that needs an option picked |
| A page with no title and no price | A free row, `row_status` `partial` |
| Out of stock | A charged row with `stock_status` `out_of_stock` and an empty price. That is the answer you asked for |
| The run is close to its timeout | The actor stops starting new work 90 seconds before the timeout and delivers what it has |

### Limitations

- Prices and stock are for the location Amazon assigns the address it read from, shown in `delivery_location`. You cannot choose a zip code in this version: the location form asked for a sign in on the pages tested.
- A parent listing that needs an option picked has no featured offer. Pass the ASIN of the exact variation.
- A residential page is about 200 KB on the wire, so a marketplace outside the US and Canada costs more per row.
- Coupons, member prices, and tax are not added to or taken from the price.

# Actor input Schema

## `products` (type: `array`):

ASINs or Amazon product URLs, up to 1,000 per run. A URL uses the marketplace in the URL; a bare ASIN uses the Marketplace setting.

## `marketplace` (type: `string`):

The store a bare ASIN is read from.

## `track_changes` (type: `string`):

true (default) or false. With true, the actor keeps each product's last reading in a key value store in your account, and a later run writes a change row when the price moves or the product goes out of or back into stock.

## `state_key` (type: `string`):

Optional name for the set of last readings, when you keep several separate tracking lists. Letters, numbers, dots, dashes, underscores.

## `previous_snapshot` (type: `array`):

Optional. Rows from an earlier run of this actor, as a JSON list. When given, changes are computed against these rows, not the stored readings.

## `max_charge_usd` (type: `string`):

Optional. The run stops before a charge that would pass this amount. Summary rows are always returned.

## `proxy_mode` (type: `string`):

auto (default): amazon.com and amazon.ca are read through the Apify proxy pool with residential as the fallback; other marketplaces use residential addresses in that country, because Amazon prices for the delivery country. residential: every product uses residential addresses in its marketplace country and is billed as product-row-local.

## `source_tag` (type: `string`):

Internal attribution tag. Leave empty.

## Actor input object example

```json
{
  "products": [
    "B00MNV8E0C"
  ],
  "marketplace": "amazon.com",
  "track_changes": "true",
  "proxy_mode": "auto"
}
```

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "products": [
        "B00MNV8E0C"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("mambalabs/amazon-product-price-stock-tracker").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = { "products": ["B00MNV8E0C"] }

# Run the Actor and wait for it to finish
run = client.actor("mambalabs/amazon-product-price-stock-tracker").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "products": [
    "B00MNV8E0C"
  ]
}' |
apify call mambalabs/amazon-product-price-stock-tracker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,mambalabs/amazon-product-price-stock-tracker"
        }
    }
}
```

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).
