Frequently asked questions

What does the Disclosed Capitol API give me access to?: Real-time disclosed congressional stock trades sourced from official U.S. House and Senate STOCK Act filings (PTRs and annual reports), structured as clean JSON. Endpoints cover per-member, per-ticker, per-committee, and recent-trades views.
Is there a free trial?: Yes. A free account comes with 750 credits to try the API. Core also comes with a 7-day free trial (one per account) that includes its full 7,500 monthly credits. A card is required at checkout for the trial, and if you cancel before it ends you're not charged. Each plan includes a monthly credit allowance: Core ($6/month) has 7,500 credits a month and 120 requests per minute, Pro ($15/month) has 30,000 credits, 240 requests per minute and webhooks, and Max ($30/month) has 125,000 credits, 600 requests per minute and webhooks.

How fresh is the data?: Disclosed Capitol ingests new STOCK Act filings on a continuous schedule throughout each trading day. Once a filing is parsed and verified, it's available through the API within minutes.
Can I redistribute or republish the data?: The underlying STOCK Act filings are public-record U.S. government disclosures, and the Ethics in Government Act restricts how financial disclosure reports may be obtained and used, other than by news and communications media for dissemination to the general public. Republishing in news or media coverage is permitted; redistributing the dataset in bulk as a standalone feed or API is not. Disclosed Capitol's value-add (parsing, normalization, performance metrics, AI analysis) is licensed under the terms posted at /terms. Attribution to Disclosed Capitol is appreciated.
How do I get an API key?: Sign up for a free account (it comes with 750 credits to try the API) and generate a key from the Account → API Keys panel. Send it in the DC-API-Key request header on every call. The API quickstart at /developers/guides/api-quickstart walks through your first call.
Does the API support webhooks for real-time alerts?: Yes — Pro and Max accounts can subscribe to HMAC-signed webhooks for real-time events (trade.created, disclosure.detected, insider.filed, lobbying.filed, contract.awarded, whale.filed), or receive the same events by email with no server required. Set up in Account → Webhooks; setup guide at /tutorials/webhooks.
What can I use the API data for?: Personal use and news or media use. Much of the data comes from financial disclosure reports filed under the Ethics in Government Act, which provides that it is unlawful to obtain or use a report “for any commercial purpose, other than by news and communications media for dissemination to the general public.” So the API is licensed for your own research and analysis, and for reporting, newsletters, and other publication to the general public. Any other use needs our written permission — email admin@disclosedcapitol.com describing your intended use. Section 9.1 of /terms has the detail. This is not legal advice; consult your own counsel if you are unsure.

It returns disclosed congress stock trades as JSON: query by member of Congress, by ticker, by committee, or pull the most recent filings. Each trade includes the transaction type, ticker, amount range, transaction date, and disclosure date, sourced from official STOCK Act filings. Start with Core's 7-day free trial at /plans.
Can I get politician stock trades through the API?: Yes. GET /politicians lists every tracked member with aggregate stats, and GET /politicians/{id}/trades returns that politician's full disclosed stock-trade history. Per-member performance fields (CAGR, alpha vs. the S&P 500) are included where enough enriched trades exist.
Does the API include both Senate and House trading data?: Yes — coverage spans both chambers. Every endpoint includes U.S. Senate and U.S. House STOCK Act disclosures (and executive-branch filers where available), so a single API key covers House trading data, Senate trading data, and cross-chamber views by ticker or committee.
