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 ## Kimchi Premium Tracker Track the **Kimchi Premium** — the price difference between Korean crypto exchanges (Upbit, Bithumb) and global exchanges (Binance) — in real time. ### What is the Kimchi Premium? The Kimchi Premium refers to the phenomenon where cryptocurrency prices on South Korean exchanges trade at a premium (or sometimes discount) compared to global exchanges. This premium is driven by capital controls, high domestic demand, and limited arbitrage pathways. ### Features - **200+ tokens tracked** — auto-detects all KRW-listed coins on Upbit - **Real-time price comparison** across Upbit, Bithumb, and Binance - **Premium calculation** with automatic USD/KRW exchange rate conversion - **Reverse premium detection** — alerts when Korean prices dip below global prices - **Upbit-Bithumb spread** — compare prices between Korean exchanges - **Threshold filtering** — only show tokens above a certain premium % - **Sorting options** — by premium (high/low) or alphabetically - **Fallback price sources** — CoinGecko backup if Binance is unavailable ### Input | Field | Type | Default | Description | |-------|------|---------|-------------| | `autoDetectAll` | boolean | `true` | Track all KRW-listed coins on Upbit (~240 tokens) | | `symbols` | string[] | `[]` | Specific tokens to track (only used when autoDetectAll is off) | | `includeUpbit` | boolean | `true` | Include Upbit exchange | | `includeBithumb` | boolean | `true` | Include Bithumb exchange | | `premiumThreshold` | number | `0` | Minimum absolute premium % to include | | `sortBy` | string | `premium_desc` | Sort: `premium_desc`, `premium_asc`, `symbol_asc` | ### Output Each result in the dataset contains: | Field | Description | |-------|-------------| | `symbol` | Token symbol (e.g., BTC) | | `binance_usdt` | Binance USDT price | | `binance_krw_equivalent` | Binance price converted to KRW | | `upbit_krw` | Upbit KRW price | | `upbit_premium_pct` | Upbit premium percentage | | `bithumb_krw` | Bithumb KRW price | | `bithumb_premium_pct` | Bithumb premium percentage | | `upbit_bithumb_spread_pct` | Price difference between Upbit and Bithumb | | `usd_krw_rate` | Exchange rate used | | `timestamp` | UTC timestamp | A **SUMMARY** key-value record is also saved with aggregate stats (average premium, top tokens, etc.). ### Pricing This Actor uses Pay-Per-Event (PPE) pricing: - **$0.003 per token tracked** (e.g., default full scan of ~200 tokens ≈ $0.60 per run) ### Use Cases - **Arbitrage monitoring** — spot premium spikes for arbitrage opportunities - **Market sentiment** — Kimchi Premium is a popular indicator of Korean retail FOMO - **Research & analytics** — track historical premium trends - **Trading signals** — combine with other indicators for entry/exit decisions ### Example Output ```json { "symbol": "BTC", "binance_usdt": 67500.00, "binance_krw_equivalent": 92340000, "upbit_krw": 95200000, "upbit_premium_pct": 3.10, "upbit_is_reverse": false, "bithumb_krw": 95050000, "bithumb_premium_pct": 2.94, "bithumb_is_reverse": false, "upbit_bithumb_spread_pct": 0.16, "usd_krw_rate": 1368.0, "timestamp": "2026-03-28T23:00:00+00:00" } ```` ### Notes - All exchange APIs are public (no API key required) - Exchange rate sourced from open.er-api.com with fallback to exchangerate-api.com - Rate limits are respected automatically - Prices are snapshot at the time of the run (not streaming) - Bithumb may be unavailable during maintenance hours (KST 01:00-08:00) - Tokens with unrealistic premiums (>15%) are filtered as likely symbol mismatches ### Disclaimer This Actor is unofficial and not affiliated with Upbit, Bithumb, or Binance. Data is provided as-is for informational purposes. # Actor input Schema ## `autoDetectAll` (type: `boolean`): Automatically detect and track all KRW-listed coins on Upbit (~240 tokens). Overrides the symbols list below. ## `symbols` (type: `array`): Specific token symbols to track (e.g., BTC, ETH, XRP). Only used when 'Track All Coins' is off. ## `includeUpbit` (type: `boolean`): Include Upbit exchange in comparison. ## `includeBithumb` (type: `boolean`): Include Bithumb exchange in comparison. ## `premiumThreshold` (type: `number`): Only include tokens with absolute premium above this threshold. Set to 0 to include all. ## `sortBy` (type: `string`): Sort results by premium percentage. ## Actor input object example ```json { "autoDetectAll": true, "symbols": [ "BTC", "ETH", "XRP", "SOL", "DOGE" ], "includeUpbit": true, "includeBithumb": true, "premiumThreshold": 0, "sortBy": "premium_desc" } ``` # API You can run this Actor programmatically using our API.
