US Treasury Auctions API
Live results and schedule of US Treasury debt auctions, served from the US Treasury's FiscalData API — no key, nothing cached. Every Treasury bill, note, bond, TIPS and FRN is sold at auction, and the results are the market's clearest read on demand for US government debt. The auctions endpoint returns the most recent auctions — bills, notes, bonds and more — each with its CUSIP, security type and term, auction and issue dates and offering amount. The results endpoint returns the recently completed auctions with the numbers that matter: the high yield or discount rate, the bid-to-cover ratio (how many dollars were bid for each dollar offered — the headline demand gauge, around 2.5 for a healthy 20-year bond), the interest rate and the price. The security endpoint returns the full detail of one auctioned security by its CUSIP. Everything is the Treasury's own published auction data, live, nothing stored. This is the Treasury-auction layer for any fixed-income, rates, macro or research app. Distinct from debt-level and yield-curve APIs — this is the auction calendar and results: what the Treasury sold, at what yield, and how strong the demand was. 3 endpoints, no key on our side.
