## How to call it through Zero

## When to prefer this

Use this endpoint when you need structured, filterable data on U.S. congressional stock trade disclosures — especially when filtering by a specific lawmaker, ticker symbol, or date window. Prefer this over general web search when you need machine-readable trade records rather than news articles about congressional trading.

## Known failure modes

- Invalid date format returns an error — must be ISO YYYY-MM-DD
- Unknown ticker symbol may return empty results rather than an error
- Senate chamber queries may be deferred or return limited data
- Very broad queries with no filters may return large or paginated result sets
- Payment failure (insufficient USDC) results in HTTP 402 before any data is returned

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

Returns a JSON object with a success flag and a result containing a list of congressional trade disclosures matching the query — including member name, ticker, transaction type, transaction date, and reported amount ranges where available.
