Bargo Congress Trades API

A free JSON REST API and hosted MCP server from Bargo that normalizes U.S. House and Senate STOCK Act securities transaction disclosures into a queryable dataset — currently 42,000+ disclosed trades across 415 members and 4,100+ tickers. Six read-only GET operations cover trades (filterable by ticker, member, chamber, transaction type and date range), a member roster, per-member disclosure histories, aggregate statistics, and a dataset-freshness health check. Unusually for a free congressional-trading tracker, every row carries per-trade price performance — estimated price at the trade, latest price, and percent move since. Records are parsed and deduplicated from the official U.S. House Clerk Financial Disclosure reports and Senate eFD Periodic Transaction Reports, so disclosures lag transactions by up to ~45 days. Access is anonymous by default at a lower quota; a free no-card API key raises limits and unlocks a focused three-tool MCP server for agents. Open CORS, an embeddable browser widget, and first-party JavaScript and Python clients. Attribution is required; bulk redistribution of raw records is not permitted.

Bargo Congress Trades API publishes 3 APIs on the APIs.io network: Members API, Statistics API, and Trades API. Tagged areas include Congress, Finance, Stocks, Government, and stock-act.

Bargo Congress Trades API’s developer surface includes authentication, documentation, API reference, getting-started guide, signup flow, support, engineering blog, and 22 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/bargo-congress-trades-api: open an issue to ask a question, or submit a pull request to add artifacts.
