How this service works
U.S. Senate Lobbying Disclosure Act filings for one named entity: total disclosed income and expenses, the issue codes lobbied on, government bodies targeted, individuals registered, and counterparties - a lobbying firm's client roster, or a client's hired firms. Normalizes the LDA issue code table and separates income from expenses, which are reported per filing and are not interchangeable. One entity per call.
Output
Returns structured LDA filing data for the queried entity: total disclosed income and/or expenses (separated and labeled as non-interchangeable), normalized LDA issue codes lobbied on, government bodies and agencies targeted, individual lobbyists registered under the entity, and counterparty relationships (either the clients a firm represents or the firms a client has hired). Results are scoped to the requested year, quarter, and entity type.
Example use cases
Corporate lobbying spend audit
“How much did Boeing spend on lobbying in 2023, which firms did they hire, and what issues were those firms lobbying on? Use the LDA filings data.”
Lobbying firm client roster review
“Give me the full client roster and billing figures for the lobbying firm Brownstein Hyatt for Q4 2023 — I want to know every company they represented and how much each paid them.”
Individual lobbyist activity lookup
“Look up the LDA filings for lobbyist John Smith in 2022 — which registrants are they associated with and which government bodies did they target?”
Technical details
Endpoint
GEThttps://bryan-hermes.lenok-gorgon.ts.net:8443/v1/lobbying?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, normalized U.S. Senate LDA lobbying disclosure data for a specific named entity — either a lobbying firm (registrant) or a company that hires lobbyists (client) — and want income/expenses separated, issue codes normalized, and counterparty relationships resolved. Prefer this over raw EDGAR or Federal Register endpoints when the question is specifically about lobbying activity, spend, or issue targeting rather than SEC filings or regulatory rulemaking.
Side effects
- Entity name not found or misspelled — returns empty results or no match
- Ambiguous entity name matching multiple filers — may return unexpected records
- Year or quarter outside available LDA data range — returns empty or error
- Limit parameter exceeding 100 — capped or rejected
- No filings exist for the specified period — empty result set
- Network or upstream LDA data source unavailable — service error
