Show HN: Finqual – Free SEC-based API for fundamentals, insider and 13F data
myztika Tuesday, March 03, 2026Hi guys,
I’ve been building investing tools for myself and kept running into the same issue:
Most free financial APIs give you price data and some fundamentals, but insider transactions and 13F filings are either delayed or locked behind relatively expensive paid tiers.
What bothered me more was that a lot of data isn’t actually sourced cleanly it’s scraped or inconsistently structured.
So I ended up building my own API called finqual.app
A few things that might be relevant here:
Data is pulled directly from SEC filings
Updated as soon as filings are published
Financial statements, insider transactions, and 13F filings included
Data is normalized and structured (so you don’t have to parse raw SEC filings)
100 free API calls/day
No credit card required
It’s basically structured SEC data without having to deal with EDGAR formatting yourself.
If anyone here is building dashboards, screeners, or running their own fundamental analysis, happy to answer questions or get feedback.
