# Track Amazon prices and stock for a list of ASINs

**Use case:** 

Monitor a fixed list of Amazon products. Each run reads the current price, list price, coupon, stock, seller and rating of every ASIN and compares it with the previous run: the changes field shows the price before and after, the change in percent and stock changes. Schedule it daily and turn on Only changed products to receive just the products whose price or stock moved.

## FAQ

### How does the Amazon price tracker task find price changes?

The Amazon price tracker task remembers the last price, stock, rating and rank of each ASIN in your own Apify account under the tracker name, and every run adds a changes field with the price before, after and the change in percent.

### How do I get only the products whose price changed?

Turn on Only changed products in the Amazon price tracker task. Unchanged products are then left out and not charged; products seen for the first time are always delivered.

### How do I run it every day?

Save the Amazon price tracker task, add a daily schedule in Apify, and connect the task's Integrations tab to email, Slack, Google Sheets, Zapier, Make or a webhook to receive each run's prices.

### How much does the Amazon price tracker task cost?

The Amazon price tracker task costs $2.50 per 1,000 products on the Apify Free plan and $2.00 on Starter, plus $0.001 per run. A daily check of 200 ASINs with 15 price changes costs about 3 cents on Starter in only-changed mode.

## About this Actor

This example demonstrates how to use [Amazon Product Scraper: Prices, BSR, Sales & Price Tracker](https://apify.com/panix/amazon-product-scraper.md) with a specific input configuration.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

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 full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/panix/amazon-product-scraper.md

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`).
