Poloniex Data Parser & API

Poloniex is a long-established cryptocurrency exchange offering spot, margin and lending markets, and StockAPIS extracts its real-time market data — spot prices, 24h volume, bid/ask spreads, order books, OHLCV candles and recent trades across 100+ trading pairs — through a single REST API. Poloniex provides an official public API, and StockAPIS normalizes it to the same schema you use for every other exchange, so you query Poloniex, Binance and Kraken the same way without maintaining separate integrations.

• Official public REST + WebSocket API, complemented by StockAPIS’s unified normalization

Quick Start

# Real-time ticker for a Poloniex pair
btc = client.poloniex.get_market_data(symbol="USDT_BTC")
print(f"Bitcoin: ${btc['last']}  ·  24h vol {btc['baseVolume']}")

const { StockAPIS } = require("stockapis");
const client = new StockAPIS({ apiKey: "your-api-key" });
