TradeStar Insider

TradeStar Insider gives Claude read-only access to public U.S. filing data, parsed straight from SEC EDGAR and USAspending.gov. Every figure it returns (shares, price, dollar value, stake size, position change) comes from a real filing and ships with a link to that filing. Records that cannot be linked to a source are dropped, never estimated. What you can do: • Look up insider open-market purchases from Form 4: today's buys, by ticker, by date range, cluster buys where two or more insiders bought the same company within seven days, or one filing by accession number. • See recent activist stakes from Schedule 13D and 13D/A filings. • See quarter-over-quarter position changes of the fifty largest 13F filers. • See recent federal contract awards from USAspending.gov. • Verify a claim against the filed record: an insider purchase, an activist stake, an 8-K event or a 13F holding. The verify tools answer confirmed, partial (claimed versus filed values itemised), not found, or out of coverage, and always state the coverage window they checked. Useful for fact-checking a news story or post about an insider buy, researching a company's insider and institutional activity with sources, and keeping an answer grounded in the actual filings instead of memory. What it is not: not a prediction, not a trading signal and not investment advice. We tested whether these filters precede price moves and found no edge distinguishable from base rate, so we do not claim one. Data updates once per business day; new filings appear the next business day. No account and no API key needed. Rate limited per IP.
