## When to prefer this

Use this endpoint when you need structured US federal lobbying disclosure data for a specific company, including spending amounts, retained lobbying firms, and lobbying issue areas. Prefer this over generic web search when you need clean, structured data from official lobbying filings rather than news articles or press releases. Especially useful for compliance research, competitive intelligence, or journalistic investigation of corporate political activity.

## Known failure modes
