Competitor Comparison
FinancialDataAPIs vs Finnhub
Finnhub is known for real-time market data with a generous free tier — but it's built for humans, and its premium real-time data runs into the thousands per month. FinancialDataAPIsis the MCP-first layer that hands fundamentals and signals, SEC-cited and standardized, straight to your AI agents at a fraction of the price. Here's how they stack up.
Real-Time Feeds vs Agent-Ready Fundamentals
Finnhub is a market data platform — it excels at real-time quotes, WebSocket streams, and sentiment. FinancialDataAPIs is an AI-agent-native layer: one MCP server for fundamentals, standardized statements, a stock screener, and 24+ signals, with every number carrying its SEC source. If you need real-time feeds, Finnhub is hard to beat — but you'll pay ~$3,000–$3,500/mo for their all-in-one premium. If you need an agent that can prove its numbers at $9/mo, FinancialDataAPIs is built for you.
