How this service works
US Treasury auction results - high yield, bid-to-cover, offering size and dates for bills, notes, bonds, TIPS and FRNs, past and upcoming
Output
A JSON object containing a count of returned items and an array of auction records, each including the security type, auction date, high yield, bid-to-cover ratio, offering size, and the data source. Optionally filtered by security type (Bill, Note, Bond, TIPS, FRN, CMB) with configurable result limit (1–30, default 10).
Example use cases
Monitor Treasury yield trends
“Get me the last 10 Treasury Bill auction results so I can see how high yields have been trending recently.”
Research upcoming TIPS auctions
“What are the most recent TIPS auction results? Show me the offering size and bid-to-cover ratio — I want to understand demand for inflation-protected securities.”
Compare FRN auction history
“Fetch the last 5 Floating Rate Note Treasury auctions with their dates and offering sizes so I can track how FRN issuance has changed.”

Endpoint
GEThttps://saylorinnovations.com/api/treasury/auctions?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, machine-readable US Treasury auction data including yield, bid-to-cover, and offering size, filterable by security type. Prefer it over scraping TreasuryDirect or using financial data aggregators when you need a lightweight, pay-per-call API with no subscription commitment. Especially useful for agents building fixed-income dashboards, macroeconomic monitors, or yield trend analyses.
Side effects
- Invalid type parameter (not one of Bill, Note, Bond, TIPS, FRN, CMB) returns an error or empty result
- Limit out of range (below 1 or above 30) may be rejected or clamped
- Payment failure (x402) if USDC payment not properly submitted
- No auctions available for the requested type returns count:0 and empty auctions array
- Upstream Treasury data source unavailable causes stale or error response
