Built for Investors & AI Builders
Institutional-grade market data for your AI, without the institutional price tag.
The gap we decided to close
The best financial data APIs and research terminals have always been priced for institutions. Hedge funds pay tens of thousands a year for live quotes, fundamentals, SEC filings, and the tooling to query them. Retail investors and independent builders are left stitching together free tiers, stale exports, and generic AI answers with no real data behind them. We think that's backwards.
Vantafin closes that gap with a REST API and an MCP server that expose the same institutional-grade dataset, live quotes, company profiles, financials, SEC filings, earnings transcripts, screeners, macro data, and more, at a fraction of what legacy providers charge. Plug your API key into Claude, Cursor, or any MCP-compatible AI assistant and let it pull real market intelligence on demand, grounded in verifiable primary sources.
Whether you build custom workflows through the REST API or connect your favorite AI through MCP, you get typed, documented access to high-quality financial data without the five-figure price tag. No black boxes. No hallucinated numbers. Just the data professionals rely on, priced for everyone.
Our Mission
To make institutional-grade financial data affordable for every retail investor and builder, so anyone can power their AI with the same market intelligence the pros use.
- MCP server with 23 tools: quotes, fundamentals, SEC filing search, transcripts, screeners, and more, ready for Claude, Cursor, and other MCP clients.
- Full REST API with OpenAPI spec for custom apps, bots, and research pipelines, same data, same rate limits.
- Institutional-quality data without the institutional budget. High quality at a cost retail investors and indie developers can afford.
MCP-first, API-ready
The MCP server is the centerpiece of Vantafin. Instead of copying data into a chat window or hoping an AI model remembers last quarter's revenue, you connect your assistant directly to live Vantafin tools. Ask Claude to screen undervalued tech stocks, pull a company's latest 10-K risk factors, or compare earnings results against estimates, and it calls real endpoints with real data.
Setup takes minutes. Add your API key to Cursor's MCP config, run a one-line command in Claude Code, or point any MCP-compatible client at our Streamable HTTP endpoint. Your AI gets structured access to quotes, financials, filing search, news, events, and more, without you writing a single integration from scratch.
Need more control? The REST API covers the same dataset with an OpenAPI-documented spec, so you can generate typed clients, build dashboards, or wire Vantafin into your own agents. Either way, you pay a fraction of what institutional data feeds cost, with no quality tradeoff.
