I\u2019ve been building a normalized dataset and API from SEC ownership filings (Forms 3, 4 and 5, including amendments). It currently covers roughly 869,000 filings and more than 2.4 million transaction line items, including issuer and reporting-owner data, roles, transaction codes, timestamps, and price-quality information.<\/p>\n
I\u2019m not launching it as a public API yet. I\u2019m looking for one person who already works with SEC ownership data and has a concrete research, backtesting, or data-engineering task they would be willing to run against it.<\/p>\n
The pilot currently provides one filtered transaction endpoint with cursor pagination through an individual, revocable API key. There is no bulk export or separate filing\/footnote endpoint yet.<\/p>\n
The documentation is available here:<\/p>\n
https:\/\/insiderfilings.info\/api\/v1\/docs\/<\/a><\/p>\n If this fits something you are already working on, please comment or DM me with a sentence or two about your use case. In return for access, I\u2019m mainly looking for candid feedback on whether the API actually saves work, where the data model is unclear, and what blocks the workflow.<\/p>\n<\/div>\n submitted by \/u\/TilmanAmbach <\/a>
