official US Treasury securities data: auction schedules, announcements and results for marketable securities (bills, notes, bonds, TIPS, FRNs, STRIPS) plus savings-bond rates (Series EE 2.40%, Series I 4.26% incl. 0.90% fixed, for issues May 1-Oct 31 2026), exposed through Treasury's public 'Web APIs Securities' and 'Web APIs Debt Information', whose documentation has moved to the fiscal.treasury.gov community API portal (the cited pages state no auth, key, format or pricing detail, so 'keyless JSON via TA_WS' is not backed by them)
