bitFlyer Data Parser & API

bitFlyer is Japan’s leading regulated cryptocurrency exchange by JPY trading volume, and StockAPIS extracts its real-time market data — last-traded prices, best bid/ask, order-book depth, trades and OHLCV candles across 30+ JPY trading pairs — through a single REST API. bitFlyer offers an official public Lightning API, and StockAPIS normalizes it to the same schema you use for every other exchange, so you query bitFlyer, Binance and Coinbase the same way without maintaining separate integrations.

Platform Overview

Market Position

• One of the largest and longest-running regulated crypto exchanges in Japan
• The reference venue for BTC_JPY and other yen-denominated pairs
• 30+ trading pairs across spot and Lightning FX perpetual futures
• Official public REST + WebSocket (Lightning) API, complemented by StockAPIS’s unified normalization

Data Coverage

StockAPIS exposes the full bitFlyer market surface:

• Spot market data — last-traded price (LTP), 24h volume, best bid/ask and sizes
• Order book — live depth snapshots with total bid/ask depth for liquidity analysis
• Trades — recent executions with timestamps, sizes and tick IDs
• OHLCV / candles — candlestick data across intervals for historical and technical analysis
• JPY pairs — yen-denominated markets (BTC_JPY, ETH_JPY and more) for Japanese-market coverage
• Lightning FX — perpetual futures pricing alongside spot

Because StockAPIS normalizes bitFlyer’s product codes, sizes and timestamps into the same response shape used for every other venue, you can add bitFlyer to an existing crypto pipeline without writing exchange-specific parsing or reconciliation logic.

Quick Start

import stockapis
 
client = stockapis.Client(api_key="your-api-key")
 
# Real-time ticker for a bitFlyer pair
btc = client.bitflyer.get_market_data(symbol="BTC_JPY")
print(f"Bitcoin: ¥{btc['ltp']}  ·  24h vol {btc['volume_by_product']:,.0f}")

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