Amendment for AI and data teams
Give your AI the record itself: the U.S. Code and C.F.R. as citable sections, bills in Congress and all 50 states, and the public companies lobbying on federal bills. Bills, law and lobbying filings come back with their official source, and each bill with its stage, last action and date, in Claude, in any MCP client, or through our API.

The side-by-side
Claude Opus 5.5 alone against Claude Opus 5.5 with the Amendment connector, on four questions about what happened after its June 2026 training cutoff. Web search was off in both runs. A point means an answer with its source.
You: Where does the Russia and Iran sanctions bill stand?
I can’t confirm where that bill stands. My training data ends in June 2026, so anything after that is past what I know.
Congress.gov will have its latest action.
No answer
You: Where does the Russia and Iran sanctions bill stand?
It’s law. It was signed on September 18, 2026. Here’s the record, with the companies that lobbied on it.

Why not web search
Search hands the model pages to read, reconcile and summarize, and someone still has to check the result. Amendment hands it fields and the official source.
The companies lobbying on a bill come from joining Senate LDA filings to SEC registrants. The companies whose 10-K names a bill or a code section come from reading the filings themselves. Because the records are already linked, the next question is one more lookup, not a fresh search.
One question
“I own NVIDIA. Which export bill is closest to law, and who else does it hit?”
The holding
Its export bills
The law under all three
Lobbied on the House-passed bill
Who it’s for
They ask: Which pending bills hit this company, and what law do they change?
In Amendment: Ticker to lobbying filings and 10-K disclosures, to the bills named, to the code sections they amend, to the rules on those sections.
Elsewhere: A lobbying-by-ticker feed, a bill tracker and a legal research tool, joined by hand.
They ask: What rules would this bill touch?
In Amendment: Bill to the U.S. Code sections it amends, to the C.F.R. parts that rest on them.
Elsewhere: A policy bill page, then a lawyer in a research tool, or a GRC tool once the rule is final.
They ask: Track this bill, then move people on it.
In Amendment: Follow, get the status alert, launch an ask, supporters co-sign by text, delivery to officials, donations.
Elsewhere: A tracker plus its grassroots module, and donations in a separate payments tool.
They ask: Which lobbyists gave to this bill’s sponsors?
In Amendment: Bill to sponsors, to lobbyist contributions, to the clients lobbying on the same bill.
Elsewhere: A bill tracker for sponsors and a money site for contributions, matched in a spreadsheet.
They ask: Answer a legal or policy question inside our own AI agent.
In Amendment: Any MCP client: search, resolve a citation, read a section’s history, and show cards for bills, law, companies and politicians.
Elsewhere: One MCP vendor for bills, another for legal research, a third for market data. No shared keys.
They ask: Did the new tax law change anything for this client?
In Amendment: The enacted law, the code sections it amended and the dates, in words an advisor can repeat.
Elsewhere: A model reading web pages, and an advisor checking its work.
