## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

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

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## Regional Price Monitor

**Track price & stock changes on mid-market and regional European retailers — the stores that global, US-centric price trackers ignore.**

Give it a list of product-page URLs and it returns, for each one: the current price, currency and stock status, whether the price changed since the last run, by how much (%), and a triggered **alert** when a move crosses your threshold, an item hits your target price, or a product goes out of stock. A persistent history is kept per product so changes are detected across runs.

Built for **EU e-commerce sellers and brands** doing competitor pricing and MAP monitoring — and callable as a tool by **AI shopping / price agents**.

---

### Why this instead of a generic Amazon tracker

If your competitors are local, your monitoring has to be local too. Global tools cover Amazon well but barely touch the regional and mid-market players that actually drive pricing in French, DACH, Nordic and Benelux markets. This Actor focuses on those retailers and correctly handles **European number formats** (e.g. `1.234,56 €`) that US-built tools routinely misread.

It reads prices from the **structured data** that modern retailers publish (schema.org / JSON-LD, microdata, Open Graph), so it works across a wide range of mid-market shops out of the box — for example **materiel.net, LDLC, TopAchat** and many similar European retailers.

> Note: a few tier-1 retailers protect their pages with aggressive anti-bot systems and may not be reachable. This Actor is purpose-built for the large, underserved mid-market segment, not for fighting enterprise-grade bot walls. Pages it cannot read are reported clearly and **never charged**.

### What you get (output per URL)

| Field | Description |
|---|---|
| `price`, `currency` | Current price and ISO currency code |
| `in_stock` | `true` / `false` / `null` if unknown |
| `price_changed`, `change_pct` | Whether price moved past your threshold, and the signed % change |
| `previous_price`, `changed_at` | Last known price and when it last changed |
| `first_seen` | `true` the first time a URL is checked |
| `alert`, `alert_reason` | Fires on threshold move, target price, or out-of-stock |
| `price_history` | The last N observations (configurable) |
| `product_title`, `is_live`, `http_status`, `error` | Context and diagnostics |

#### Example record

```json
{
  "url": "https://www.materiel.net/produit/202404260002.html",
  "checked_at": "2026-06-09T16:20:51Z",
  "is_live": true,
  "http_status": 200,
  "currency": "EUR",
  "price": 926.95,
  "in_stock": false,
  "first_seen": false,
  "price_changed": true,
  "previous_price": 999.95,
  "change_pct": -7.30,
  "changed_at": "2026-06-09T16:20:51Z",
  "alert": true,
  "alert_reason": "price dropped 7.3% (999.95 -> 926.95); out of stock",
  "product_title": "MSI GeForce RTX 4070 Ti SUPER VENTUS 2X OC",
  "price_history": [
    { "price": 999.95, "currency": "EUR", "in_stock": true, "checked_at": "2026-06-08T16:20:00Z" },
    { "price": 926.95, "currency": "EUR", "in_stock": false, "checked_at": "2026-06-09T16:20:51Z" }
  ],
  "error": null
}
````

### Input

| Field | Type | Default | Description |
|---|---|---|---|
| `productUrls` | string list | — | Product-page URLs to monitor (press Enter after each one) |
| `alertThresholdPercent` | integer | `5` | Ignore price moves smaller than this percentage |
| `targetPrice` | string | — | Optional. Alert when price ≤ this value (use `.` for decimals) |
| `priceHistoryLimit` | integer | `30` | How many recent observations to keep per product |
| `proxyConfiguration` | proxy | Residential | Residential proxy recommended — retailers block datacenter IPs |

### How it works

1. Loads each page in a **real browser** (so client-rendered prices appear) through a **residential proxy**.
2. Blocks images, fonts, media and third-party trackers before loading — pages load faster and cost less.
3. Extracts price, currency and stock from **structured data** in priority order: JSON-LD (`schema.org/Product`) → microdata → Open Graph → a visible-text fallback that understands European number formats.
4. Compares against the **persistent price history** (a named Key-Value Store that survives across runs) to detect changes and fire alerts.
5. Charges **only on a successful price retrieval** — blocked, failed, or price-less pages cost you nothing.

### Use it from an AI agent

The input schema is self-describing, so AI shopping and price-comparison agents can discover and call this Actor to check live prices and stock before recommending or buying.

### Scheduling & alerts

Run it on an Apify **schedule** (e.g. hourly or daily) to build history and catch drops. Point a webhook at the dataset to push changes/alerts into your own systems.

### Pricing

Pay-per-event: you are billed **$0.02 per product successfully checked**. Pages that are blocked, unreachable, or have no detectable price are **not charged**. Platform costs (proxy and compute) are included — no surprise usage fees.

# Actor input Schema

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

List of product-page URLs to check. Each URL must point to a single product page on a mid-market / regional European retailer (works well with stores that publish structured product data, e.g. materiel.net, LDLC, TopAchat). The Actor returns one result object per URL. Tip: strip tracking query parameters (e.g. ?gclid=, utm\_\*) so the same product is tracked under a stable key across runs.

## `alertThresholdPercent` (type: `integer`):

Minimum absolute price-change percentage (vs the last stored price) required to mark price\_changed=true and raise an alert. Smaller moves are recorded but not flagged. Set to 0 to flag every change. Default 5.

## `targetPrice` (type: `string`):

Optional numeric value. When the observed price is at or below this value, the result's alert flag is set with reason 'at/below target'. Enter a plain number using a dot as decimal separator, e.g. 299.99.

## `priceHistoryLimit` (type: `integer`):

Maximum number of most-recent price observations kept per product in the persistent history and returned in the price\_history array. Default 30.

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

Residential proxy is strongly recommended and used by default: retailers block datacenter IPs. Leave as-is to use Apify Residential.

## Actor input object example

{
  "productUrls": [
    "https://www.materiel.net/produit/202404260002.html",

  ],
  "alertThresholdPercent": 5,
  "priceHistoryLimit": 30,
  "proxyConfiguration": {
    "useApifyProxy": true,
