## 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

## Anime Figure Price Drop & Restock Alerts API

Track anime figure product pages and get structured JSON alerts when prices drop, products restock, products sell out, or preorder status changes.

This Actor is built for anime figure collectors, deal channels, Discord bots, storefront monitors, and resale tools. Instead of returning a raw price snapshot, it compares each run to the previously stored state and emits usable change events.

---

### What it detects

- `first_seen`
- `price_drop`
- `price_increase`
- `restocked`
- `sold_out`
- `availability_change`

Each dataset item includes the current price, previous price, current availability, previous availability, and a concise `change_summary`.

---

### Best use cases

- Anime figure restock alerts
- Nendoroid and scale-figure watchlists
- Crunchyroll, Good Smile, and specialty-store monitoring
- Discord or Telegram deal bots for anime merch
- Reseller backends watching sellouts and restocks

---

### Input

```json
{
  "productUrls": [
    "https://www.goodsmileus.com/products/nendoroid-belle-14589",
    "https://www.goodsmileus.com/products/hello-good-smile-sesshomaru-15314"
  ],
  "niche": "anime figures",
  "emitUnchanged": false,
  "followCanonicalUrl": true,
  "timeoutSecs": 20,
  "userAgent": "Your Company research@yourcompany.com"
}
````

| Field | Type | Notes |
|---|---|---|
| `productUrls` | string\[] | Product pages to monitor. |
| `niche` | string | Optional label stored on each output item. |
| `emitUnchanged` | boolean | If `true`, writes current state even when nothing changed. |
| `followCanonicalUrl` | boolean | Uses the page canonical URL when present. |
| `timeoutSecs` | integer | Per-request timeout. |
| `userAgent` | string | Set this to your company name and email for polite crawling. |

***

### Output fields

| Field | Meaning |
|---|---|
| `event_types` | One or more change events for the product |
| `price_amount` | Current parsed price |
| `previous_price_amount` | Previous stored price |
| `availability` | Normalized availability (`in_stock`, `out_of_stock`, `preorder`, `backorder`, `unknown`) |
| `previous_availability` | Previous stored availability |
| `change_summary` | Human-readable description of what changed |
| `tracked_at` | ISO timestamp of the current run |

***

### How it works

The Actor fetches each product page, extracts structured data from JSON-LD, Open Graph, meta tags, and text fallbacks, then stores the latest known state in Apify key-value storage. On the next run, it compares the new snapshot to the prior one and emits only meaningful changes by default.

That makes it suitable for scheduled runs, webhook pipelines, Discord bots, and deal-alert backends.

***

### Notes

- Extraction quality is best on stores that expose product schema or standard meta tags.
- Some stores block automated traffic; blocked pages will be returned with an `error`.
- This Actor is intentionally watchlist-first. It monitors URLs you already care about rather than discovering every figure in a category.
