# Amazon Price Tracker: Drop Alerts & Daily CSV

Source: https://zentor.ai/use-cases/amazon-price-tracker

Amazon price tracker run by an AI agent: daily CSV exports, drop alerts, and change summaries. No code.

## Prompt

```text
Every morning, scrape the top 100 Baby Toys on Amazon, save a CSV, and alert me if any price drops more than 10 percent.
```

Variations:

- **ASIN watchlist**: Check these Amazon ASINs daily, log price and BSR into a CSV, and ping Slack when any item falls below my target price.
- **Competitor brand**: Monitor Amazon search results for my competitor brand name each day, capture price and rating, and write a short change summary.
- **Category under $50**: Scrape Amazon Kitchen gadgets under $50 every weekday, keep only items with 4 stars or higher, and export a CSV to my workspace.

## How it works

1. **Say what to watch on Amazon**: Category, keyword, ASIN list, schedule, and how you want alerts. Plain English is enough.
2. **Zentor opens a browser and pulls the list**: It runs in a real browser session, paginates results, and writes structured rows instead of screenshots.
3. **Get a CSV plus a short change summary**: Files land in your workspace on the schedule you set, with optional Slack or Telegram pings for drops.

## What you can monitor

- Category top lists: Top N results for a category or keyword, with price and rank.
- ASIN watchlists: A fixed set of products checked on a schedule.
- Drop alerts: Notify only when price moves past a threshold you set.
- CSV exports: Structured files in your workspace for Sheets or BI tools.
- Change summaries: A short note on what moved since the last run.
- Other storefronts: Same monitoring pattern on Walmart, eBay, or a brand site when you ask.

## FAQ

### How does an Amazon price tracker work in Zentor?

You describe the category or ASINs and the schedule. Zentor opens a browser, collects the fields you asked for, saves a CSV, and can alert you when prices move.

### How often can it run?

Hourly, daily, weekly, or a custom schedule. Most teams run once a day and keep the CSV history in the workspace.

### How many products can one run cover?

A single task can page through a search and collect on the order of 100 products. Split categories into separate tasks when you need more.

### Is this a Keepa alternative?

Different shape. Keepa is a fixed Amazon dashboard. Zentor is an agent you instruct in plain English, with CSV output and the option to watch sites beyond Amazon.

### Do I need APIs or code?

No. Describe the monitoring job in chat. Zentor handles the browser session, extraction, and scheduling.

### Can it watch marketplaces other than Amazon?

Yes. The same pattern works on other storefronts when you name them in the task.
