Finage
Finage is a UK-based real-time and historical market-data provider spanning US and global stocks, forex, crypto, indices, ETFs, CFDs, and decentralized-exchange data, delivered over REST and WebSocket in JSON. It authenticates with an API key and offers no ongoing free tier — only a 3-day trial — before paid plans starting around $599/month for delayed global stock data and scaling to $999+/month for real-time US coverage. Live-checked in July 2026: the API host returns no `Access-Control-Allow-Origin` header on either simple or preflighted requests, so it cannot be called directly from browser JavaScript.
