What You Get
A Real API, Not a Scraper
01

Dual-Chamber Coverage

Both House and Senate disclosures in one unified endpoint. Data sourced directly from official House Clerk Periodic Transaction Reports (PTRs) and Senate Electronic Financial Disclosures (eFD).

House + Senate
02

Deep Filtering

Query by member name, ticker symbol, political party, chamber, state, transaction type (purchase, sale, exchange), date range, and disclosure amount. Get exactly the slice of data you need — no client-side filtering required.

9 Filter Params
03

Clean, Normalized Data

Raw congressional filings are messy — inconsistent member names, variable date formats, unstructured amounts. We normalize everything into consistent JSON with standardized fields before it hits the API.

Structured JSON
04

Updated Hourly

New filings are ingested within an hour of appearing on official House Clerk and Senate eFD sources. No stale data, no manual refreshes. The feed stays current automatically.

Hourly Ingestion
05

Historical Depth

Coverage back to 2008 — the full era of STOCK Act electronic disclosures. 63,000+ individual transactions across hundreds of current and former members of Congress. Enough data for serious historical analysis.

2008 – Present
06

Free. Actually Free.

No trial period, no credit card, no usage caps that kick in after a week. Congressional disclosure data is public information. We believe clean access to it should be free. Get a key and start querying.
