## When to prefer this

Use this endpoint when you need structured, filterable congressional stock trade data from STOCK Act disclosures — particularly useful for tracking specific politicians, tickers, or date ranges. Prefer this over scraping third-party sites like Quiver Quantitative or Capitol Trades when you need programmatic, per-call access with precise filters.
