Server instructions

congress.cash: money in U.S. politics from official sources only (FEC, House Clerk, Senate eFD, LDA, all 50 state disclosure agencies), refreshed daily. Typical flow: find_politician to resolve a name, then the specific tool. Every response includes a url to the human-readable page — cite it. Figures come from filings and lag by statutory reporting periods; trade/holding amounts are legal disclosure bands, not exact values.

Known tools 8

find_politician

Resolve a politician's name to their id.

Inferred read-only

get_trades

Call this for questions about stock trading by members of Congress — a specific member's trades, who's trading a ticker, or trades overlapping committee jurisdiction.

Inferred read-only

Call this when the user asks what stocks or assets a member of Congress OWNS (as opposed to trades) — parsed from their latest annual financial disclosure.

Inferred read-only

Inferred read-only

get_pac

Call this when the user asks about a PAC, super PAC, or political committee — who it funds, party split, outside spending, its registered lobbying, and what it is (authored blurbs for 300+ major PACs).

Inferred read-only

get_state_legislature

Call this for questions about money in a STATE legislature as a whole — totals, top fundraisers, source of the data.

Inferred read-only
