Legislative sessions
Regular and special sessions from 2021 through 2027, with convening and sine die dates.
98%
of bills carry at least one sponsor
94%
of bills carry at least one text version
34%
of bills carry a recorded roll call
Read that last figure as a fact about legislatures rather than a gap in the data. Most bills die in committee without a recorded vote ever being taken, so no source can show a roll call that does not exist. Where a vote happened, we carry every member's individual position, not just the tally.
Elections
The same API carries the races those bills are being run on. One call returns a state's entire slate — every contest, every candidate, every measure — and the official vote counts underneath them.
/v1/midterms?state=FL returns every congressional, statewide-executive, and state-legislative race, each with its primary, runoff, and general kept as separate contests so a primary margin is never mistaken for a general-election result.
Vote counts flow from 45 state election-office feeds across 44 states and D.C., with precincts reporting and a capture timestamp. Every row carries the official source URL, so any number on your screen can be traced back to the state that published it.
Statewide measures across 38 states with ballot title, full text, summary, and the Secretary of State page they came from — enough to render a voter guide without a second source.
Congressional, state senate, and state house districts with boundaries as GeoJSON on request, simplified to the tolerance you ask for. Enough to draw a live results map from this API alone.

]We report what the official source reports: vote totals, the share of precincts reporting, and the timestamp it was captured. We do not call races, project winners, or publish a forecast. If you need a call, that is a decision your product makes on top of numbers you can audit — every result row carries the state URL it came from.
Our MCP server drops the entire legislative corpus into Claude, Cursor, and any MCP-compatible client — search bills, pull roll-call votes, and read full text in plain language, with your own API key.
