## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

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

# README

## Cardmarket Deal Finder - Underpriced TCG Listings

Finds **live Cardmarket listings priced well under the card's own trend price** - condition-aware, so a cheap damaged card never masquerades as a deal. Works on Pokémon, Magic, Yu-Gi-Oh!, Lorcana, One Piece and ten more games. One row per underpriced offer with condition, language, price, ship-from country and the exact discount versus Cardmarket's official trend price.

### Quick start

1. Type what you hunt: **"charizard"**, "umbreon vmax", "black lotus".
2. Set your bar: minimum **25% under trend** and **Excellent or better** are the defaults.
3. Run. Each row is one live offer:

```json
{
  "name": "Charizard (PGO 010)",
  "game": "Pokémon",
  "condition": "NM",
  "language": "English",
  "priceEur": 2.8,
  "quantity": 3,
  "locationCountry": "Germany",
  "trendEur": 5.6,
  "avg30Eur": 5.1,
  "discountPct": 50,
  "productUrl": "https://www.cardmarket.com/en/Pokemon/Products/Singles/Pokemon-GO/Charizard-PGO010",
  "priceGuideDate": "2026-08-28"
}
```

### How it works

1. Loads Cardmarket's **official daily price guide** (the trend and 30-day average of every product) - the benchmark.
2. Searches your query and short-lists products whose cheapest listing already undercuts trend by your threshold.
3. Opens those product pages and inspects the actual offers: **condition, language, price, quantity, ship-from country**.
4. Delivers only offers that clear both bars - the discount and the minimum condition.

### FAQ

**Can I use this as a plain Cardmarket scraper?**
Yes - set `minDiscountPct` to **0** and the actor returns *every* live offer of the products your search matches: price, condition, language, quantity and ship-from country per listing (set `minCondition` to PO to include damaged copies). It is a Cardmarket listings scraper without the part that should not be scraped: seller identity.

**Why condition-aware?**
The cheapest listing of a card is usually the most damaged one. A "50% under trend" Poor-condition card is priced correctly, not underpriced. This actor compares like with like: set `minCondition` to NM and only near-mint bargains reach your dataset.

**What is the trend price?**
Cardmarket's own smoothed market price per product, from its official daily price guide. Every row carries the trend, the 30-day sale average and the guide date, so you can audit every flagged deal.

**Does it show the seller?**
No. Seller identity is deliberately never extracted - you get the product link and open the offer on Cardmarket yourself. The output contains market facts only: prices, conditions, languages, countries.

**Why do I need the Site Unblocker proxy?**
Cardmarket protects its pages with anti-bot measures. The preset proxy configuration (Apify Site Unblocker) handles that server-side. Runs without it will fail with a clear message.

**How fresh are the results?**
Live - the offers are read from the product pages at run time, and benchmarked against today's price guide.

**How do I watch a niche continuously?**
Schedule the run (hourly or daily) with your query and thresholds. Combine with the price band (`priceMinEur`/`priceMaxEur`) to stay in your buying range.

**Which games work?**
Pokémon, Magic, Yu-Gi-Oh!, Lorcana, One Piece, Digimon, Flesh and Blood, Star Wars Unlimited, Dragon Ball Super, Final Fantasy, Weiss Schwarz, Cardfight!! Vanguard, Battle Spirits Saga, Riftbound and Force of Will.

**What does a run cost?**
You pay per delivered deal row plus a small start fee. `maxProducts` and `maxItems` cap the run; a focused query typically costs cents.

**A deal was gone when I clicked it.**
Real bargains go fast - that is what makes them bargains. Schedule frequent runs for the niches you care about.

# Actor input Schema

## `game` (type: `string`):

Which trading card game to hunt deals in.

## `searchQuery` (type: `string`):

What to hunt for, e.g. "charizard", "umbreon vmax", "black lotus".

## `minDiscountPct` (type: `integer`):

An offer counts as a deal when it undercuts the card's trend price by at least this much. Set 0 for listings mode: every offer of the matched products, like a classic Cardmarket scraper (minus seller data).

## `minCondition` (type: `string`):

Ignore offers below this condition - a cheap damaged card is not a deal.

## `languages` (type: `array`):

Only count offers in these languages. Japanese and Korean prints trade far below the trend price, so mixing them in fakes discounts. Empty = all languages.

## `priceMinEur` (type: `integer`):

Skip cards whose trend price is below this - filters bulk noise.

## `priceMaxEur` (type: `integer`):

Skip cards whose trend price is above this.

## `maxProducts` (type: `integer`):

How many candidate products to open and inspect per run.

## `maxItems` (type: `integer`):

Upper bound on delivered deal rows.

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

Cardmarket requires Apify's Site Unblocker proxy (the UNBLOCKER group, preset here).
