Alpha Vantage API Integration

Financial data API providing stocks, forex, crypto, technical indicators, fundamental data, economic indicators, and AI-powered news sentiment analysis.

Quick Start

Authentication

# Environment variable (recommended)
export ALPHAVANTAGE_API_KEY="your_api_key"

# Or in .env file
ALPHAVANTAGE_API_KEY=your_api_key

Basic Usage (Python)

import requests
import os

API_KEY = os.getenv("ALPHAVANTAGE_API_KEY")
BASE_URL = "https://www.alphavantage.co/query"

def get_quote(symbol: str) -> dict:
    """Get real-time quote for a symbol."""
    response = requests.get(BASE_URL, params={
        "function": "GLOBAL_QUOTE",
        "symbol": symbol,
        "apikey": API_KEY
    })
    return response.json().get("Global Quote", {})

# Example
quote = get_quote("AAPL")
print(f"AAPL: ${quote['05. price']} ({quote['10. change percent']})")

Using Python Package

# Time series data
ts = TimeSeries(key=API_KEY, output_format='pandas')
data, meta = ts.get_daily(symbol='AAPL', outputsize='compact')

# Technical indicators
ti = TechIndicators(key=API_KEY, output_format='pandas')
rsi, meta = ti.get_rsi(symbol='AAPL', interval='daily', time_period=14)

Free vs Premium Features

Free Tier Includes

• 25 requests per day
• 5 requests per minute
• Historical time series (20+ years)
• 50+ technical indicators
• Fundamental data
• Forex and crypto
• Economic indicators
• News sentiment

Premium Required

• Unlimited daily requests
• Adjusted time series
• Realtime US market data
• 15-minute delayed data
• Insider transactions
• Advanced analytics
• Priority support

Best Practices

1. Cache responses - Data doesn't change frequently
2. Use compact outputsize - Unless you need full history
3. Batch requests wisely - 25/day limit is strict
4. Handle rate limits - Check for "Note" key in response
5. Use pandas output - With alpha_vantage package
6. Store historical data - Avoid re-fetching same data

Installation

# Official Python wrapper
pip install alpha_vantage pandas

# For async support
pip install aiohttp

Usage with Pandas

from alpha_vantage.timeseries import TimeSeries
from alpha_vantage.techindicators import TechIndicators
import pandas as pd

# Initialize with pandas output
ts = TimeSeries(key=API_KEY, output_format='pandas')
ti = TechIndicators(key=API_KEY, output_format='pandas')

# Get daily data
data, meta = ts.get_daily(symbol='AAPL', outputsize='compact')

# Get indicators
sma, _ = ti.get_sma(symbol='AAPL', interval='daily', time_period=20)
rsi, _ = ti.get_rsi(symbol='AAPL', interval='daily', time_period=14)

# Combine
analysis = data.join([sma, rsi])
