The filing it was read fromread_from names the 10-K and its accession number. Open the filing on Thaler or on SEC EDGAR. Sources and revisions goes down to the XBRL fact.
The value, as filedvalue is a decimal string, never a float, so 416161000000 arrives exactly as Apple’s 10-K states it: $416.2 billion of revenue in fiscal 2025.
The release that served itmeta.release names the day’s data release and says whether its checks passed. Every response carries it.
