Veridion Disclosure API · early access

The public record, made usable.

Congressional stock disclosures and SEC ownership filings are public — and scattered across separate government systems with separate formats, separate identifiers, and no common schema. Veridion collects them at the source, parses them, links every row to its official document, and serves one normalized dataset. You verify any number against the government's own file without asking us.

What the dataset is

STOCK Act transactions. House and Senate periodic transaction reports: member, ticker, transaction type, trade date, filing date, disclosed amount range, owner type — with the filing-delay arithmetic already done.
SEC ownership filings. Form 3 and Form 4 insider activity, 13F institutional positions, and Schedule 13G/13D beneficial ownership, parsed from EDGAR.
A receipt on every row. Each record carries the office it came from, the document identifier, and a URL that resolves to the government's own file.
Honest coverage numbers. Every response states its own completeness — how many rows matched, what share carry parsed amounts, what share link to receipts. Gaps are reported, never papered over.

What it deliberately is not

No market data. Quotes, price history, and chart data are licensed inputs on our consumer product and are not redistributed here.
No third-party datasets. Only records Veridion collects itself from the official government systems are licensed. Rows sourced from commercial providers are excluded, and the machine-readable coverage endpoint reports that split.
No recommendations. Amounts stay as the bounded ranges disclosed in the filings. No motive is inferred. Identification data, not investment advice.
