Marketstack is a Global
Stock Market Data API.

Alpha Vantage

Lead on Technical Indicators (50+ built-in indicators like RSI, MACD).

Marketstack Strength

Exchange Volume. Marketstack supports 70+ global exchanges and 125,000+ tickers. Alpha Vantage is heavily US-centric; their global data often requires specific "Market" parameters that are less documented. Marketstack doesn’t have the crypto data but we have a dedicated, easy-to-use API for that https://coinlayer.com/

Fetch Historical Stock
Market Data with Ease.

Marketstack

Offers a cleaner `date_from` and `date_to` parameters at the API level, or use limit and offset for pagination, getting exactly what you need. Saving developers from parsing massive JSON just to get last week's prices.

# Marketstack example for historical data (last 30 days)

from datetime import datetime, timedelta

end_date = datetime.now()
start_date = end_date - timedelta(days=30)

url = f'https://api.marketstack.com/v1/eod?access_key={api_key}&symbols={symbol}&date_from={start_date.strftime("%Y-%m-%d")}&date_to={end_date.strftime("%Y-%m-%d")}'

r = requests.get(url) data = r.json()

# Each item in data['data'] is a daily entry

Alpha Vantage

Historical data for many symbols is full (15+ years). You can only specify a `date` parameter to retrieve options data for any trading day in the past. Resulting in a massive JSON response and slow to parse.

Clean, Consistent JSON
Responses for Developers

Alpha Vantage's JSON structure is messy: They use keys with spaces and numbers, which is a challenging for dot-notation in JavaScript or Typed classes in TypeScript.

Marketstack's JSON is clean: Standardized, snake_case, more data points, and flat array structures.
