ANSWERS “how did Rep. X vote on bill Y” / “what were X’s last 20 votes” / “did X vote against the budget resolution” — one House member’s recorded position (Yea, Nay, Present, Not Voting, or not on the roll) on roll calls, newest first, from the U.S. House Clerk’s roll-call votes. Filter by bill (e.g. “H R 1”), question_contains (matched against question, bill number and description) or a roll range. Quorum calls and Speaker elections are left out unless include_non_recorded is true. Every response names its congress, session, the last roll it covers and data_as_of. House only: a Senate request, an unknown member, or a Congress/session not held each return a named reason, never an empty list.

Parameters

Name	Type	Required	Description
`bill`	string	no	Legislation number as the Clerk prints it, e.g. “H R 1”, “H J RES 104”, “S 2403” (punctuation and spacing ignored; exact match).
`question_contains`	string	no	Case-insensitive text to match in the vote question, bill number or description, e.g. “suspend the rules”, “continuing appropriations”.
`from_roll`	number	no	First roll number to consider.
`to_roll`	number	no	Last roll number to consider.
`include_non_recorded`	boolean	no	Include quorum calls and Speaker-election rolls (default false).
