## Pricing

from $2.10 / 1,000 results

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?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Amazon Price Tracker – Change Alerts by ASIN

Track Amazon product prices, availability, ratings, reviews, brands, and price changes across runs. Supports regional stores and optional proxy.

### Start quickly

Paste this input, replace the example values, and run the Actor:

```json
{
  "productUrls": [
    "https://www.amazon.com/dp/0132350882"
  ],
  "emitOnlyChanges": false,
  "proxyConfiguration": {
    "useApifyProxy": false
  },
  "maxItems": 10
}
```

### Output

Each successful result is a normalized dataset row. Export JSON, CSV, Excel, call through the API, schedule runs, or connect webhooks and integrations. The Actor enforces a hard maximum item cap and records partial failures in the run summary.

### Pricing and responsible use

Launch pricing is **$0.003 per successful result** plus the small start event shown in the Pricing tab. Third-party API, proxy, and platform compute costs are separate where applicable. Collect only data you are authorized to use and follow the source platform’s terms, privacy rules, and applicable law.

# Actor input Schema

## `productUrls` (type: `array`):

Amazon product detail URLs containing an ASIN.

## `emitOnlyChanges` (type: `boolean`):

Skip unchanged products after the first run.

## `stateStoreName` (type: `string`):

Named key-value store used to compare this run with previous runs.

## `proxyConfiguration` (type: `object`):

Optional Apify Proxy configuration. Residential access may be required for protected public pages.

## `maxItems` (type: `integer`):

Hard cap for emitted dataset rows and pay-per-event charges.

## Actor input object example

```json
{
  "productUrls": [
    "https://www.amazon.com/dp/0132350882"
  ],

# 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 = {
    "productUrls": [
        "https://www.amazon.com/dp/0132350882"
    ],
    "emitOnlyChanges": false,
    "proxyConfiguration": {
        "useApifyProxy": false
    },
    "maxItems": 10
};

// Run the Actor and wait for it to finish
const run = await client.actor("signal_lab/amazon-price-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 = {
    "productUrls": ["https://www.amazon.com/dp/0132350882"],
    "emitOnlyChanges": False,
    "proxyConfiguration": { "useApifyProxy": False },
    "maxItems": 10,
}

# Run the Actor and wait for it to finish
run = client.actor("signal_lab/amazon-price-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 '{
  "productUrls": [
    "https://www.amazon.com/dp/0132350882"
  ],
  "emitOnlyChanges": false,
  "proxyConfiguration": {
    "useApifyProxy": false
  },
  "maxItems": 10
}' |
apify call signal_lab/amazon-price-tracker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,signal_lab/amazon-price-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).
