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 4 API contracts indexed on the APIs.io network, including Members API, Statistics API, Trades API, and 1 more. Tagged areas include Congress, Finance, Stocks, Government, and stock-act.

The Bargo Congress Trades API catalog on APIs.io includes 1 Spectral governance ruleset.

Bargo Congress Trades API’s developer surface includes authentication, documentation, API reference, getting-started guide, signup flow, support, engineering blog, and 23 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.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

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/.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Government Cloud (FedRAMP, GovRAMP, G-Cloud)	distribution	9.6 (thin)	1	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 3

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
