Livermore

Data coverage and freshness

get_data_coverage

Read-onlyIdempotent

What data Livermore has and how fresh it is: the Form 4 filing-date range, the 13F quarters loaded (with the number of filers), the latest complete 13F quarter, the number of curated superinvestors, the Schedule 13D, 13G and Form 144 filing-date ranges, the filing-date range of politicians' trade reports (the congress field: reports by members of the U.S. Congress), the date ranges of company filings (10-K, 10-Q, 8-K), FINRA short interest, daily short volume, weekly ATS volume and SEC fails-to-deliver, the number of companies with financial statements, and the number of companies with a market cap with the newest close date used (market_caps); each of these is null until loaded and has its own last_updated. Also the last successful data updates (ISO 8601 UTC), the update schedule and the usage limits of this server. Call it to check whether a date or quarter is covered.
