Bitfinex Data Parser & API

Bitfinex is a long-established cryptocurrency exchange known for deep liquidity, advanced margin trading and a peer-to-peer funding market, and StockAPIS extracts its real-time market data — spot and margin prices, order book depth, OHLCV candles, recent trades and funding stats across 300+ trading pairs — through a single REST API. Bitfinex offers an official public REST and WebSocket API, and StockAPIS normalizes it to the same schema you use for every other exchange, so you query Bitfinex, Binance and Coinbase the same way without maintaining separate integrations.

Platform Overview

Market Position

• One of the longest-running crypto exchanges, favored by professional and institutional traders
• 300+ trading pairs spanning spot, margin and perpetual derivatives
• A distinctive peer-to-peer funding (margin lending) market with its own rates and book
• Deep liquidity on major pairs makes it a key reference venue for price discovery
• Official public REST + WebSocket API, complemented by StockAPIS’s unified normalization

Data Coverage

StockAPIS exposes the full Bitfinex market surface:

• Spot market data — real-time last price, 24h volume, bid/ask, daily change absolute and relative
• Order book — live depth snapshots with configurable precision (P0–P4) and length
• Trades — recent trades with timestamps, prices and sizes
• OHLCV / candles — candlestick data across intervals for historical and technical analysis
• Funding market — peer-to-peer lending rates, funding book and funding ticker data
• Tickers — 24h high/low, volume and price-change statistics per pair

Quick Start

import stockapis
 
client = stockapis.Client(api_key="your-api-key")
 
# Real-time ticker for a Bitfinex pair
btc = client.bitfinex.get_market_data(symbol="tBTCUSD")
print(f"Bitcoin: ${btc['last_price']}  ·  24h vol {btc['volume']}")

const { StockAPIS } = require("stockapis");
const client = new StockAPIS({ apiKey: "your-api-key" });
 
// Live order book (precision P0, top 25 levels)
const book = await client.bitfinex.getOrderBook({ symbol: "tBTCUSD", precision: "P0", len: 25 });
console.log(book.bids[0], book.asks[0]);
