Fundamental API for Multibagger Metrics
A specialized financial data API focused on delivering deep historical fundamental metrics—like decade-long EBITDA and asset growth—tailored for retail algorithmic traders. It bridges the gap between prohibitively expensive institutional feeds and free APIs that lack historical depth.
Why this matters
As a retail algorithmic trader trying to backtest long-term fundamental investing frameworks, you frequently hit a brick wall when sourcing data. You discover a proven study about historical stock multibaggers and want to code a strategy based on EBITDA and asset growth over a ten-year span. However, when you look for data providers, institutional-grade feeds are prohibitively expensive, and the affordable APIs lack historical depth or accuracy. You end up relying on clunky third-party ranking tools or manually verifying screener results, breaking the automation loop that attracted you to quant trading in the first place.

MVP Scope · 1–2 weeks
- Identify the top 5 fundamental metrics required for multibagger strategies (e.g., EBITDA, ROIC, total assets).
- Evaluate and select a cost-effective upstream wholesale data provider with minimum 10-year history.
- Set up a cloud database to ingest and standardize this data for the S&P 500.
- Build a basic REST API with an endpoint that returns the historical series for these specific metrics.
- Create a minimal landing page focused on the specific value prop of 'affordable multibagger data for quants'.
- Develop a simple Python script example demonstrating how to backtest with the API.
- Implement API key generation and usage tracking.
- Integrate a payment gateway for self-serve subscription signup.
- Write a comprehensive documentation page showing query formats.
- Launch a beta program on developer forums offering 1-month free for feedback.
Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1The cost of licensing reliable historical fundamental data without survivorship bias might erode retail-friendly profit margins.
- 2Target users might tolerate the clunkiness of existing broad platforms rather than paying for a specialized data feed.
- 3Retail quants often prefer high-frequency technical trading over slow, fundamental, long-term strategies, limiting the total addressable market.
