## 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/docs.md):

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

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

## MTG Metagame Scraper

Apify Actor that scrapes **Magic: The Gathering competitive metagame data**:
archetype meta shares, recent tournaments with an importance rating, standings
with player names, and full decklists of the top finishes.

Supported formats: `standard`, `modern`, `legacy`, `vintage`, `pioneer`,
`commander`, `pauper`.

### Data sources

| | MTGTop8 (default) | MTGGoldfish |
|---|---|---|
| Archetype meta shares | ✅ | ✅ |
| Archetype key cards | ❌ | ✅ |
| Real tournaments with standings | ✅ | ❌ |
| Tournament importance (1–5 stars) | ✅ | ❌ |
| Full decklists (main + sideboard) | ✅ | ❌ |

Pick the source with the `source` input option (`mtgtop8`, `mtggoldfish`, or
`both`).

### Input

```json
{
    "formats": ["modern", "standard"],
    "source": "mtgtop8",
    "maxEvents": 8,
    "minPlayers": 100,
    "decklistsPerEvent": 2,
    "includeDecklists": true,
    "requestDelaySecs": "1.0",
    "incremental": false,
    "stateRetentionDays": 30
}
````

- **formats** — which formats to scrape.
- **source** — data source: `mtgtop8` (tournaments + decklists), `mtggoldfish`
  (meta shares + key cards), or `both`.
- **maxEvents** *(MTGTop8 only)* — tournaments per format, picked by importance
  (star rating) then recency.
- **minPlayers** *(MTGTop8 only)* — skip tournaments below this size. Player
  counts are only visible on event pages, so up to 3× `maxEvents` events are
  probed. Tip: use `50` for smaller formats like Vintage or Legacy.
- **decklistsPerEvent** *(MTGTop8 only)* — full decklists (top finishes)
  downloaded per tournament.
- **requestDelaySecs** — polite delay between requests (keep ≥ 1.0).
- **incremental** *(MTGTop8 only)* — remember tournament ids across runs (in
  the named key-value store `mtg-metagame-seen-events`) and only emit NEW
  events. MTGTop8's format page only shows the last few days, so a scheduled
  incremental run accumulates tournament history over time with no duplicates
  — and already-seen tournaments cost no extra requests (fewer paid results,
  faster runs). The `metagame` item (meta shares) is always emitted: it is a
  point-in-time snapshot, not an accumulating stream.
- **stateRetentionDays** — days before a seen tournament id is forgotten
  (keeps the incremental state from growing forever). Default 30.

### Output

Dataset items come in two shapes, discriminated by `type`.

**`metagame`** — one per format+source:

```json
{
    "type": "metagame",
    "format": "modern",
    "source": "mtgtop8",
    "fetched_at": "2026-07-15T10:00:00+00:00",
    "total_archetypes": 49,
    "archetypes": [
        {"name": "Boros Aggro", "meta_share": 0.11, "category": "Aggro"}
    ]
}
```

MTGGoldfish archetypes have `key_cards` instead of `category`.

**`event`** — one per qualifying tournament (MTGTop8 only):

```json
{
    "type": "event",
    "format": "modern",
    "source": "mtgtop8",
    "id": "88185",
    "name": "MTGO Showcase Challenge",
    "stars": 3,
    "importance": "major",
    "date": "12/07/26",
    "online": true,
    "players": 448,
    "decks": [
        {
            "deck_id": "869090",
            "rank": "1",
            "archetype": "Ruby Storm",
            "player": "Fatone",
            "decklist": {
                "mainboard": [{"qty": 4, "card_name": "Ruby Medallion"}],
                "sideboard": [{"qty": 4, "card_name": "Orim's Chant"}]
            }
        }
    ]
}
```

Only the first `decklistsPerEvent` decks carry a `decklist`.

`rank` is a **string, possibly composite** (`"1"`, `"3-4"`, `"5-8"`): shared
placements are how MTGTop8 reports brackets below the finals. Don't parse it
as an integer — sort by its first number if you need an ordering.

Note: no source exposes reliable per-archetype **win rates** for free; that is
why the output deliberately has no win-rate field.

### Notes on importance (stars)

MTGTop8 rates events 1–5 stars. The scraper prioritizes tournaments by stars,
then recency, and maps them to labels: `minor` (≤1★), `competitive` (2★),
`major` (3★), `premier` (4–5★). Use this to weight results: a Top 8 at a
premier event says more about the metagame than a win at a small local.

### Use as a library

The parsers live in the installable `mtg_metagame` package — this repo is the
single source of truth for them (the DeckAssistant backend consumes it as a
pip dependency):

```bash
pip install "mtg-metagame @ git+ssh://git@github.com/MartoEporedia/mtg-metagame-actor.git"
```

```python
from mtg_metagame import MTGTop8Client

client = MTGTop8Client()
data = await client.fetch_metagame_full("modern", max_events=8, min_players=100)
```

Override `PoliteClient.fetch` to plug in your own caching or transport.

### Running locally

```bash
python3 -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
apify run   # or: python -m src (reads storage/key_value_stores/default/INPUT.json)
```

### Fair use

The scraper enforces a ≥1s delay between requests and fetches a bounded number
of pages per run (roughly `formats × (1 + 3×maxEvents + maxEvents×decklistsPerEvent)`
worst case). Please keep the delay at 1 second or higher. MTGGoldfish sits
behind Cloudflare: if requests get blocked on the platform, enable Apify Proxy.

# Actor input Schema

## `formats` (type: `array`):

MTG formats to scrape. Supported: standard, modern, legacy, vintage, pioneer, commander, pauper.

## `source` (type: `string`):

MTGTop8: meta shares + real tournaments with importance rating and full decklists. MTGGoldfish: meta shares + key cards only (no tournaments). 'both' fetches from the two sources.

## `maxEvents` (type: `integer`):

(MTGTop8 only) How many qualifying tournaments to include per format, picked by importance (star rating) and recency.

## `minPlayers` (type: `integer`):

(MTGTop8 only) Tournaments with fewer players are skipped. Set to 0 to include everything. Tip: use 50 for smaller formats like Vintage or Legacy.

## `decklistsPerEvent` (type: `integer`):

(MTGTop8 only) How many full decklists (top finishes) to download per tournament. Each decklist costs one extra request.

## `includeDecklists` (type: `boolean`):

(MTGTop8 only) Disable to skip decklist downloads entirely (faster, fewer requests).

## `requestDelaySecs` (type: `string`):

Polite rate limiting towards mtgtop8.com. Keep at 1.0 or higher.

## `incremental` (type: `boolean`):

Remember tournament ids across runs (named key-value store) and only emit NEW events. Ideal for scheduled runs: results accumulate over time without duplicates, and already-seen tournaments cost no extra requests. Meta shares are always emitted.

## `stateRetentionDays` (type: `integer`):

How long (days) a tournament id stays in the incremental state before being forgotten. Only used with incremental mode.
