Twelve Data Data Parser & API

Twelve Data is a developer-focused financial market data provider covering stocks, ETFs, forex, crypto, commodities and indices worldwide, and StockAPIS extracts its data — real-time and historical quotes, OHLCV time series, technical indicators and fundamentals — through a single unified REST API. Twelve Data offers an official REST and WebSocket API, and StockAPIS normalizes it to the same schema you use for every other source, so you query Twelve Data, Polygon and Alpha Vantage the same way without maintaining separate integrations.

Platform Overview

Market Position

• A widely adopted multi-asset market data API aimed at developers, fintechs and quant teams
• Single API spanning stocks, ETFs, forex pairs, cryptocurrencies, commodities and indices

Data Coverage

StockAPIS exposes the full Twelve Data surface:

• Real-time quotes — live price, change, percent change, bid/ask and intraday OHLC
• Time series (OHLCV) — candlestick data from 1-minute to monthly intervals for history and backtesting
• Forex & crypto — currency pairs and digital-asset rates with the same schema as equities
• Technical indicators — 100+ built-in indicators including SMA, EMA, RSI, MACD and Bollinger Bands
• Fundamentals & reference — company profiles, earnings, dividends, splits and symbol/exchange metadata
• Economic & index data — major indices and macro series for cross-asset context

Quick Start

import stockapis
 
client = stockapis.Client(api_key="your-api-key")
 
# Real-time quote for a US equity from Twelve Data
quote = client.twelve_data.get_quote(symbol="AAPL")
print(f"Apple: ${quote['close']}  ·  {quote['percent_change']}%")

const { StockAPIS } = require("stockapis");
const client = new StockAPIS({ apiKey: "your-api-key" });
 
// 1-minute OHLCV time series
const series = await client.twelveData.getTimeSeries({
  symbol: "AAPL",
  interval: "1min",
});
console.log(series.values[0]);
