## 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`).

## Amazon Deals & Coupon Monitor: Catch Every Coupon the Day It Appears

Scan any Amazon search or category and get back every product currently carrying a clippable coupon or a deal badge, with the real price after the coupon is applied. Run it again and it tells you which coupons just appeared, which ended, and which deals started.

Built for deal sites, resellers and shoppers who need the discount while it is still live, not after it expires.

### How it works

```mermaid
flowchart LR
    A["Search terms"] --> B["Render Amazon search<br/>(residential proxy, pinned country)"]
    B --> C["Coupon badge +<br/>deal badge + list price"]
    C --> D["Price after clipping<br/>= effective price"]
    D --> E{"Compare with<br/>last run"}
    E -->|coupon now there| F["coupon appeared"]
    E -->|coupon now gone| G["coupon ended"]
    E -->|badge now there| H["deal started"]
    F --> I[("Alert rows")]
    G --> I
    H --> I
```

The number that matters is `effectivePrice`: the shelf price with the coupon applied. A "$5.00 off coupon" on a $24.04 item is reported as $19.04, so you can filter on what a buyer actually pays rather than on the sticker.

### Built for

- **Deal sites and newsletters** sourcing genuinely live discounts
- **Resellers** finding stock that is cheap right now, coupon included
- **Brand teams** watching how aggressively rivals discount a category
- **Shoppers** waiting for a specific product to drop below a number

### Input

```json
{
  "keywords": ["coffee mug", "standing desk"],
  "marketplace": "US",
  "dealsOnly": true,
  "onlyCoupons": true,
  "minSavingPercent": 20
}
```

| Setting | What it does |
| --- | --- |
| `keywords` | Search terms, tracked separately across runs |
| `marketplace` | Which Amazon site to scan: `US`, `UK`, `DE` and 12 more |
| `dealsOnly` | Use Amazon's own Today's Deals filter. Turn off to find coupons Amazon does not badge |
| `pagesPerKeyword` | How deep into the results to scan |
| `onlyCoupons` / `onlyDeals` | Keep only clippable coupons, or only badged deals |
| `minSavingPercent` | Only discounts worth acting on |
| `onlyChanged` | Return only coupons and deals that appeared or ended |

### Output

```json
{
  "asin": "B0C74C5T2L",
  "keyword": "coffee mug",
  "title": "Insulated Stainless Steel Travel Mug, 20oz",
  "price": 24.04,
  "currency": "$",
  "listPrice": 29.99,
  "discountPercent": 19.8,
  "hasCoupon": true,
  "couponAmount": 5,
  "couponPercent": null,
  "couponText": "$5.00 off coupon applied",
  "dealBadge": "limited-time-deal",
  "effectivePrice": 19.04,
  "totalSavingPercent": 36.5,
  "rating": 4.4,
  "changeType": "coupon-appeared",
  "url": "https://www.amazon.com/dp/B0C74C5T2L",
  "checkedAt": "2026-09-15T18:25:11.902Z"
}
```

`changeType` is the field to filter on. It is one of `coupon-appeared`, `coupon-ended`, `deal-started`, `deal-ended`, `price-drop`, `price-rise`, `new-deal`, `unchanged` or `first-run`.

### Turn it into a deal alert

Set `onlyChanged` and `onlyCoupons` and schedule it a few times a day. The first run records what is already discounted. Every run after that returns only the coupons that just appeared.

```json
{
  "keywords": ["mechanical keyboard"],
  "onlyChanged": true,
  "onlyCoupons": true,
  "minSavingPercent": 15
}
```

### Run it as an API

```bash
curl -X POST "https://api.apify.com/v2/acts/arched_friend~amazon-deals-monitor/run-sync-get-dataset-items?token=YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "keywords": ["coffee mug"],
    "marketplace": "US",
    "onlyCoupons": true
  }'
```

### Pricing

You pay $0.02 for each search actually scanned, however many products it returns. A search returning 70 products costs the same as one returning 5.

| Scanning 10 categories, 3x daily | Monthly cost |
| --- | --- |
| Checking by hand | not realistically possible |
| Most deal-tracking tools | $30 to $200 per month |
| This Actor | $18 per month |

### Common questions

**Why is `listPrice` sometimes null when Amazon shows a struck-through price?** Because that slot is not always an RRP. Amazon reuses it for unit pricing and for ad placements, which on one real search page produced 21 rows out of 73 whose "list price" sat *below* the selling price. Anything not above the selling price is rejected rather than reported as a saving.

**Does it clip the coupon for me?** No. It finds and prices them; clipping happens in your own Amazon account.

**Why do some deal badges come back null?** Only real discount badges are kept. A "Best Seller" or "Amazon's Choice" flag is not a discount, so it is deliberately not reported as one.

**Should I turn `dealsOnly` off?** Turn it off when you want coupons Amazon has not badged as deals. It scans more products for the same price, but a larger share of them will have no promotion at all.

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

Which Amazon site to scan. Use a country code such as US, UK or DE.

## `dealsOnly` (type: `boolean`):

Apply Amazon's own Today's Deals refinement so the search only returns products already carrying a promotion. Turn off to scan the whole search and find coupons Amazon does not badge as deals.

## `pagesPerKeyword` (type: `integer`):

How many pages of results to scan for each search term.

## `onlyChanged` (type: `boolean`):

Return only coupons that appeared or ended, deals that started or ended, and price moves. Turn this on for scheduled monitoring.

## `onlyCoupons` (type: `boolean`):

Keep only products carrying a clippable coupon.

## `onlyDeals` (type: `boolean`):

Keep only products carrying a deal badge such as a Lightning Deal or a limited time deal.

## `minSavingPercent` (type: `integer`):

Keep only products saving at least this much off the list price, coupon included.

## `minPrice` (type: `integer`):

Keep only products at or above this price after the coupon. 0 means no minimum.

## `maxPrice` (type: `integer`):

## `minRating` (type: `integer`):

Keep only products rated at least this many stars. 0 means no minimum.

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

Amazon blocks datacentre IPs, so this defaults to Apify residential proxy pinned to the marketplace country.

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).
