Coincheck Data Parser & API

Coincheck is one of Japan’s leading regulated cryptocurrency exchanges, owned by the listed Monex Group, and StockAPIS extracts its real-time market data — BTC/JPY and altcoin prices, order books, recent trades and ticker statistics across 20+ yen-quoted pairs — through a single REST API. Coincheck offers an official public API, and StockAPIS normalizes it to the same schema you use for every other exchange, so you query Coincheck, Binance and Kraken the same way without maintaining separate integrations.

Platform Overview

Market Position

• A top-tier Japanese exchange, among the largest by registered domestic users
• Registered with Japan’s Financial Services Agency (FSA) and operated by Coincheck, Inc., a Monex Group company
• The reference venue for JPY-denominated crypto price discovery in the Japanese market
• Official public REST + WebSocket API, complemented by StockAPIS’s unified normalization

Data Coverage

StockAPIS exposes the full Coincheck market surface:

• Spot market data — real-time last price, 24h high/low, volume and bid/ask spread for JPY pairs
• Order book — live depth snapshots with bids and asks for liquidity and slippage analysis
• Trades — recent executed trades with price, size, side and timestamps
• Ticker — best bid/ask, last traded price and rolling volume per symbol
• JPY pairs — Bitcoin and major altcoins quoted directly in Japanese yen
• Exchange info — available trading pairs and supported currencies

Quick Start

import stockapis
 
client = stockapis.Client(api_key="your-api-key")
 
# Real-time ticker for a Coincheck JPY pair
btc = client.coincheck.get_market_data(symbol="btc_jpy")
print(f"Bitcoin: ¥{btc['last']}  ·  24h vol {btc['volume']}")

const { StockAPIS } = require("stockapis");
const client = new StockAPIS({ apiKey: "your-api-key" });
 
// Live order book for BTC/JPY
const book = await client.coincheck.getOrderBook({ symbol: "btc_jpy" });
console.log(book.bids[0], book.asks[0]);
