Trades by ticker or member
Every disclosed transaction with the member and their position, the transaction and filing dates, the owner type and the disclosed amount band.
STOCK Act disclosures · REST API · MCP
Congressional trading API and MCP server for STOCK Act data
Follow stock trades disclosed by members of the US House and Senate: trades by ticker or by member, member search, disclosed net-worth bands and market-wide aggregates. Query the REST API in your own code, or ask Claude, ChatGPT or any MCP client whether Congress traded a stock this year.
Free: 100 requests a day, no credit card. One account works with REST and MCP.

What the API and the MCP tools cover
Both surfaces read the same store the Equibles pages render, so a figure on the site and a figure in your code agree.
Members and net worth
Search members by name and read the net-worth bands their annual disclosures report.
Market-wide activity
Aggregate what Congress is buying and selling across the market over a period, and see the most traded names.
REST endpoints and MCP tools
Every endpoint below is a GET under the api.equibles.com/v1 base URL, authenticated with an API key. Each MCP tool answers the same question in plain English from Claude, ChatGPT or any connected client.

Read the disclosures correctly
Every amount is a disclosed dollar band rather than an exact figure, so totals are ranges and rankings use band midpoints.
The STOCK Act's general filing deadline is 45 days after a trade, and late or amended records can arrive later still, so a trade can post well after it happened.
What the API preserves
- The member and the position they held as disclosed
- The transaction date and the filing date, kept separate
- The amount band exactly as filed, never a point estimate
- The owner type, so a spouse's or dependent's trade is not read as the member's own
- Paging and stable member identifiers for reproducible pulls

Frequently asked questions
What is a congressional trading API?
It turns the stock transactions members of Congress disclose under the STOCK Act into structured endpoints: trades by ticker or member, member search, net-worth bands and market-wide aggregates.
How exact are the amounts?
They are not. Members disclose a dollar band, such as $15,001 to $50,000, never an exact figure. Equibles keeps the band as filed; rankings use band midpoints and say so.
How quickly does a trade appear?
The STOCK Act's general deadline is 45 days after the trade, and late or amended disclosures can arrive later. Both the transaction date and the filing date are kept.
Can I get congressional trades in Claude or ChatGPT?
Yes. Connect the Equibles MCP server and ask whether Congress traded a stock; the GetCongressionalTrades tool answers by ticker and GetMemberTrades by member. The REST API returns the same data as JSON.
Is there a free congressional trading API?
Yes. The Equibles free tier includes 100 requests a day, shared across the REST API and MCP server, with no credit card. Paid plans raise the limit.
