Example prompt: Can you pull up the federal lobbying profile for Pfizer over the last 3 years — I want to see which firms they hired, what they spent each year, and which policy issues they're focused on?

## When to prefer this

Use this endpoint when you need a fast, structured summary of a specific company's federal lobbying history — hired firms, issue areas, and spending trends — sourced from official Senate LD-2 disclosures. Prefer it over general web search when you need structured, machine-readable lobbying data with year-by-year spend and a clear verdict signal. Not suitable for state-level lobbying or non-US entities.

## Known failure modes

- Company name not found in lobbying disclosures — returns zero filings and empty arrays
- Ambiguous company name matches multiple clients — matchedClientNames may include unrelated entities
- Spend data may be incomplete if filings omit dollar amounts — filingsWithAmounts < filings total
- Very recent filings may not yet appear due to disclosure lag
- Non-US or foreign-only companies will return no results

## How this service works

Federal lobbying for a company: who they hire, what they spend, which issues, and how recent the activity is.

## Output

Returns a structured object with: matched client names found in disclosures, total reported spend, spend broken down by year, top lobbying firms with filing counts, top policy issues by mention frequency, overall filing counts, signals summarizing recency and activity level, a plain-language verdict, data source attribution, and a retrieval timestamp.
