Vantafin is a financial data and research platform that gives individual investors, analysts, and developers institutional-grade market data without the enterprise price tag. In one place you get company profiles, live and delayed quotes, SEC filings back to 1994, fundamentals, earnings transcripts, a stock screener, AI research chat, and a full developer API, including an MCP server for AI assistants.

Who is Vantafin for?
Vantafin serves three overlapping audiences:
- Individual investors and analysts who want reliable data and research tools without a Bloomberg or FactSet subscription.
- AI builders who want to feed verifiable market data into assistants like Claude, Cursor, and other MCP clients, or into their own apps over REST and WebSocket.
- Developers who need a clean, well-documented financial data API with predictable pricing.
For example, a long-term investor might screen for profitable dividend growers, open the company profile for each result, then ask AI Chat to summarize the latest 10-K risk factors. A developer might instead pull the same fundamentals through the REST API.
What data does Vantafin cover?
Vantafin combines several data types into a single, cross-linked experience:
- Quotes: live and delayed prices for stocks and ETFs, plus intraday minute charts.
- Fundamentals: income statement, balance sheet, and cash flow, with history.
- SEC filings: 10-K, 10-Q, 8-K, and more, indexed since 1994.
- Earnings: dates, call transcripts, and investor materials.
- Corporate actions: dividends, stock splits, and IPOs.
- Ownership: institutional holders and insider (Form 3/4/5) transactions.
- News: market-wide and per-ticker headlines.
- Macro: key economic series for context.
Data availability varies by security type (for example, ETFs show holdings instead of earnings transcripts).
