Data Infra · 06
Who is buying, selling and disclosing, from official filings only: congressional trades since 2012, insider transactions and 13F holdings since 2006, fund and activist letters, all ticker-linked.
Accurate · Reliable · Source‑backed
Five datasets · five endpoints
Call one stream or join them all on the same ticker and CIK spine. Every endpoint returns rows that carry their official source and, where it matters, both dates: when it happened and when it was disclosed.
Filed trades from official House and Senate disclosures, with both the trade date and the filing date preserved.
Form 4 transactions: who bought, who sold, clustered where it matters, plus insider-related news.
13F-derived positions with quarter-over-quarter changes per institution and per name.
Collected and ticker-tagged: the arguments behind the positions.
Collected and ticker-tagged: campaigns, demands and targets.
The data, not a description of it
Every disclosure ships with both of its dates and its official source, so you always know what was knowable when.
Bargo Verification Layer · Accurate · Reliable · Source‑backed
A scanned disclosure lands. Here is what happens before it becomes a row:
Disclosures arrive as messy scanned documents. The resolver can only choose among securities that exist, or decline. It cannot invent a symbol.
The day the trade happened and the day it was disclosed are different facts. Both are preserved on every row, forever.
Insider clusters, holding changes and committee-sector overlaps are arithmetic on verified rows, never narrative.
Only then does the disclosure ship: officially sourced, dual-dated, resolved or honestly unresolved. Two decades of it, on one identifier spine. See the full Verification Layer →
Access
Ownership questions with receipts: who bought, who sold, who filed, and when.
Wire it into Claude, Cursor or your own agents, or pull straight into pandas.
Congressional, insider and holdings data as clean endpoints, dual-dated throughout.
Who runs on it
13F changes, insider clusters and congressional flow on the same names, same spine.
Every row traces to the government document it came from. Clean enough for a memo.
Filed-versus-traded preserved on every row: event studies without date archaeology.
