About

Finnhub gives you a free API key that unlocks stock quotes, company profiles, financial statements, market news, and earnings calendars from one service. You can use it to build an earnings calendar notifier, to add live-ish price quotes to a side project, or to read market headlines programmatically for a research digest. The free tier's per-minute allowance is generous enough for personal bots and small apps.

Details

Free to start. You may need a free key, but no credit card.
