Implementation notes
When to use Marketstack
Marketstack covers 125,000+ tickers from 70+ global exchanges — broader international coverage than Alpha Vantage at the free tier. With 100 calls/month free, it suits one-off lookups or a personal watchlist app that fetches end-of-day prices weekly rather than daily.
Common pitfalls
- 100 calls/month is one of the most restrictive free quotas in the finance category — roughly 3 calls/day. A daily polling script for a 5-stock watchlist burns the monthly budget in 20 days. Design around this constraint from day one.
- Free tier is HTTP-only. The HTTPS endpoint (`https://api.marketstack.com`) returns a 401 on free keys with an error stating SSL is not enabled. For browser-facing or production apps, HTTPS requires at least the $9.99/month Basic plan.
- The `demo` key returns only AAPL data and is subject to a separate, undocumented rate limit that differs from real keys. Do not write integration tests against the demo key — test with a real free key.
- End-of-day data (`/v1/eod`) is the primary free endpoint. Intraday and real-time data are paid features. The API returns a 403 for intraday endpoints on free keys without a clear message about the tier requirement.
