Feature comparison

“—” indicates a feature we haven't confirmed on the competitor's public surface. If something here is out of date, email admin@disclosedcapitol.com and we'll update.

When to choose Disclosed Capitol

• You want to build with the data — there's a clean REST API with a free tier (/developers).
• You want AI-assisted analysis on top of the raw filings — Chad answers questions like “which committee chairs are buying defense names this quarter?” directly.
• You want committee-level views, not just individual member pages — every committee (House Armed Services, Senate Banking, etc.) has its own aggregated portfolio.
• You want performance metrics (CAGR, alpha vs. the S&P 500, win rate) computed per-member, not just trade lists.

When Capitol Trades might fit

Capitol Trades has been around longer and is a fine option if you only need the trade-feed view and don't care about API access, AI analysis, or aggregated committee portfolios. Both surfaces are pulling from the same primary STOCK Act filings, so the underlying data is the same — the differentiation is in what each platform layers on top.

Does Capitol Trades have an API?

As of July 2026, Capitol Trades does not advertise a public developer API on its site. If you searched for a “Capitol Trades API,” what you're usually after is programmatic access to congressional stock-trade data — and that is exactly what Disclosed Capitol offers.

• A documented REST API with a free tier — clean JSON for politicians, trades, tickers, and committee portfolios.
• Per-member performance fields (CAGR, alpha vs. the S&P 500) in the response.
• New STOCK Act filings ingested within minutes of public posting.
• Get a key on the API access page — no credit card for the free tier.

We only state what a competitor's public surface shows. If Capitol Trades has since launched an API, email admin@disclosedcapitol.com and we'll update this page.
