Sources & accuracy
We mirror the record — we don’t replace it
Legislative data is public, but it’s scattered across dense official sites. Here’s exactly where Bill100’s data comes from, how fresh it is, and where an AI summary should make you go read the primary text.
Principles
How Bill100 handles the record
We mirror, we don't originate
Every bill, sponsor, action and status on Bill100 is sourced from Congress.gov and GovTrack — the two authoritative public feeds for federal legislation. We don't invent or infer data that isn't in the public record.
Updated on an ongoing cadence
Bill status, actions and sponsor data are refreshed on a recurring pull from both sources, not a one-time import. A bill that moves in committee today shows that change on its next sync, not next quarter.
AI summaries can simplify or omit detail
The plain-English summary on every bill is generated from its actual official text and current status — but any summary can compress nuance a full reading wouldn't. It's a starting point, not a replacement for the primary source.
Every bill links to its primary source
Congress.gov and GovTrack links are attached to every bill, every API response and every MCP tool result, so you (or an agent's human reviewer) can verify anything Bill100 shows before relying on it.
API keys stored hashed
API keys are stored hashed, never in plaintext, and can be rotated or revoked instantly from your account if one is ever exposed.
An information tool, not advice
Bill100 mirrors the public U.S. legislative record from Congress.gov and GovTrack and adds plain-English AI summaries. It is an information tool, not legal, compliance or lobbying advice, and it is not affiliated with the U.S. Congress or any government agency. AI summaries can simplify or omit detail — every bill links to the official source; verify there before you rely on it.
FAQ
Accuracy questions
Where does Bill100's data actually come from?
Congress.gov (the official U.S. Congress legislative database) and GovTrack (a long-running independent tracker), cross-referenced for status and action data. Every bill page links to both.
How often does status update?
Bills are re-synced from both sources on a recurring schedule — a status change on Congress.gov or GovTrack lands on Bill100 on the next sync, not instantly, but typically within the same day.
Can I trust the AI summary?
Treat it as a fast, usually-accurate starting point, not the final word. It's grounded in the bill's real text and status, but every bill page and API response links to the official source so you can verify anything before relying on it.
Is a tailored AI impact analysis legal advice?
No. Bill100 mirrors the public U.S. legislative record from Congress.gov and GovTrack and adds plain-English AI summaries. It is an information tool, not legal, compliance or lobbying advice, and it is not affiliated with the U.S. Congress or any government agency. AI summaries can simplify or omit detail — every bill links to the official source; verify there before you rely on it.
Is Bill100 affiliated with Congress?
No — Bill100 is an independent index that mirrors the public legislative record. It is not affiliated with the U.S. Congress, Congress.gov or any government agency, and doesn't provide legal, compliance or lobbying advice.
