Example prompt: Pull up the US Senate LDA lobbying filings for Pfizer (PFE) from 2021-01-01 to 2024-01-01 — I want to see their registrants, quarterly periods, and how much they reported spending each period.

## When to prefer this

Use this endpoint when you need structured, per-filing lobbying spend data tied to a US public company's stock ticker, sourced directly from Senate LDA disclosures. Prefer it over general news or financial APIs when you need official government filing data with registrant names, quarters, and dollar amounts.

## Known failure modes

- Invalid or unrecognized ticker returns empty results or error
- Date range with no filings returns empty array
- Non-US-listed ticker may return no data
- Malformed date format (not YYYY-MM-DD) may cause query failure
- Rate limiting or payment failure returns 402

## How this service works

US federal lobbying disclosures for a public company (sourced from US Senate LDA filings). Pass ticker and optionally a from/to window (YYYY-MM-DD; defaults to ~3 years); returns each filing with the registrant name, the period (year + quarter), reported lobbying income/expenses in USD, and a link to the official Senate filing. Use it to track a company’s lobbying spend over time. Data by Finnhub.

## Output

A list of lobbying filing records, each containing the registrant name, period (year and quarter), reported lobbying income and/or expenses in USD, and a direct link to the official US Senate filing.
