Second Dot launches StockFit API for audit-grade SEC data

Second Dot LLC has launched StockFit API, a U.S. financial data service built for developers, quant researchers and institutional workflows. The platform emphasizes point-in-time SEC data, traceability to original filings and pricing meant to make commercial use more accessible.

Why it matters: - StockFit API targets users who need point-in-time financial data they can audit back to the original SEC filing. - The launch is aimed at developers, quant researchers and institutional investment workflows that need cleaner data and less lookahead bias. - Second Dot LLC is positioning the product as a lower-cost alternative to traditional providers that often charge more for commercial use and auditability.

What happened: - Second Dot LLC announced the launch of StockFit API on July 28, 2026. - The service is built on SEC EDGAR filing data and is designed to provide audit-grade accuracy. - Each number served by StockFit API includes an audit trail back to the filing that generated it. - New filings are processed daily as soon as they become available. - A free tier is available for users who want to evaluate the data before paying.

The details: - StockFit API launches with more than 90 endpoints. - The coverage includes insider transactions, institutional holders, beneficial owners, executives, company peers and revenue segmentation. - The feature set also includes 20+ years of clean fundamentals. - The platform covers all U.S. stocks and funds, including delisted securities. - Additional features include IPOs, earnings, stock splits, dividends, fund holdings, daily fund holdings, sector- and industry-aware key metrics, and a native MCP server for AI agent integrations. - Full API documentation is available at the full API documentation. - StockFit API is built so every number can be traced to the filing that produced it.

Between the lines: - Traditional data vendors often normalize financial statements in ways that make the underlying numbers harder to audit. - StockFit API is trying to differentiate itself by keeping the SEC filing trail visible all the way through the data pipeline. - Founder Andy Reimann said the goal is to give small startups a legitimate, high-quality data source they can afford and trust. - Reimann said the product reflects the kind of multi-provider setup he once needed for his own long-term investment app. - Marcus M. Simmons of LogicFortress said the platform’s point-in-time temporal rollback ledger helped eliminate lookahead bias in a quant execution engine.

What's next: - Second Dot LLC is pushing adoption through developer documentation and a free tier. - The company’s next test is whether the combination of traceability, breadth and pricing can win users who need both commercial flexibility and point-in-time accuracy. - More information is available at developer resources. - The company also lists social channels on LinkedIn and X.
