Second Dot LLC Launches StockFit API, Delivering Audit-Grade US Financial Data Built for Developers and Quantitative Research
LOS ANGELES, CA, UNITED STATES – Second Dot LLC today announced the official launch of StockFit API, a comprehensive US financial data platform designed specifically for software engineers, quantitative researchers, and institutional investment workflows. Operating directly from the SEC EDGAR filing system, the platform establishes a high standard for data integrity by delivering full audit traceability for every value it serves.
Available at https://developer.stockfit.io/, StockFit API was created to solve a persistent industry challenge: the lack of verifiable, point-in-time data at an accessible price point. While legacy data vendors often lock clean historical datasets and audit logs behind high subscription fees, StockFit API provides a transparent, developer-first alternative. The platform includes a generous free tier, enabling developers and research teams to thoroughly evaluate the infrastructure before committing to paid commercial plans.
At launch, the API features more than 90 dedicated endpoints that extend well beyond standard financial statements. The service provides extensive coverage across insider transactions, institutional holdings, beneficial ownership, executive compensation, corporate governance, company peer groups, and detailed revenue segmentation. Every normalized data point links directly to its source filing and date, ensuring that derived fields and subsequent filing amendments are clearly tracked.
“What sets StockFit apart is the audit trail,” said Christopher Gordon, Founder and CEO of Quantum Trade Intelligence. “Every fact in the normalized statements carries its source filing and date, with derived fields called out separately and amendments handled properly.”
A core feature of the platform is its Point-In-Time (PIT) Temporal Rollback Ledger. This architecture enables quantitative analysts to view financial statements precisely as they appeared on any given date in history, systematically eliminating lookahead bias during algorithmic backtesting.
“StockFit is the only financial API I’ve found that provides a true Point-In-Time (PIT) Temporal Rollback Ledger out of the box,” said Marcus M. Simmons of LogicFortress. “Exposing the exact SEC amendment trail allowed me to mathematically eliminate Lookahead Bias from my quantitative execution engine in a single weekend. It is an absolute game-changer for deterministic backtesting.”
The platform covers over 20 years of clean fundamentals spanning all US equities and funds, including delisted entities. Additionally, StockFit API offers a native Model Context Protocol (MCP) server, allowing modern AI agents and automated workflows to query SEC data directly with built-in audit verification.
Andy Reimann, founder of Second Dot LLC, developed the service after experiencing the constraints of existing financial data markets firsthand while building investment software.
“I’ve been on both ends now,” said Reimann. “Five years ago, I needed to subscribe to five different providers just to get all the data needed for my long-term investment app. It was absolutely impossible from a cost perspective to get everything I needed. Now I’m creating the API I wish existed back then.”
