From the Senate Office of Public Records (SOPR) LDA database via the official bulk download endpoint or the LDA search API. Both are federal public record. SleekRank reads them directly without paid intermediaries. The bulk download covers LD-1 registrations and LD-2 quarterly reports back to 1999.

Filings are submitted on quarterly deadlines (the 20th of January, April, July, and October). SOPR publishes new filings shortly after submission. Setting cache_duration to weekly captures the quarterly spike plus any amended or late-filed reports without overfetching during the long gaps between deadlines.

{entity-name-slug}-{registrant-id} reads well in SERP and stays unique even when entity names overlap (e.g. two different firms named "Capitol Group"). The registrant ID is the canonical SOPR identifier and survives firm rebrands and mergers without forcing a URL change in the corpus.

Yes. Each LD-2 carries a quarterly expenditure or income figure. Sum the four quarters of a calendar year for the headline annual total and render the quarterly breakdown below as a small table. Most journalism queries are about annual figures, so the aggregated number belongs in the hero block above the filings detail.

Each LD-2 lists registered lobbyists by name with a flag indicating whether they previously held a covered government position. Render the list with the prior-government flag visible since the revolving-door angle is the dominant editorial framing on lobbying coverage.

When an entity files an LD-2 termination report, its registrant_type updates and no further quarterly filings appear. Keep the page published with the historical filings visible and a "no longer registered" banner. Removing the page would harm the historical research use case that the corpus is built to serve over the long term.

Yes. The LDA issue codes are 78 three-letter codes with a hierarchical structure. Render the issues for each filing as tag pills colored by category (tax, trade, telecom, energy, etc). A tag cloud at the corpus level lets users find every entity lobbying on a given issue, with each pill linking into a filtered archive.

No. LDA covers federal lobbying meeting the income and time thresholds. State-level lobbying, grassroots lobbying, and informal influence outside the LDA threshold are not in the SOPR file.
