How this service works
US Treasury debt auctions (bills, notes, bonds, TIPS, FRNs): upcoming announced auctions or recent results with term, offering amount, high yield and bid-to-cover demand. Official Fiscal Data.
Output
A JSON object containing a list of auction records, each with: security type (Bill/Note/Bond/TIPS/FRN), CUSIP, term (e.g. '4-Week', '10-Year'), coupon rate (if applicable), maturity date, auction date, offering amount in USD, high yield percentage, and bid-to-cover ratio. Also includes a source attribution and a flag indicating whether results are upcoming or recent.
Example use cases
Monitor T-bill auction demand
“Show me the last 15 Treasury bill auctions with their bid-to-cover ratios and high yields so I can see how demand has been trending.”
Check upcoming TIPS auctions
“Are there any upcoming US Treasury TIPS auctions announced? Give me the details including term and offering amount.”
Track 10-year note auction results
“What were the results of the most recent Treasury note auctions — specifically the high yield and how much was offered?”

Endpoint
POSThttps://api.vextorium.com/subastas-tesoro-eeuu-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, up-to-date US Treasury auction data — either upcoming scheduled auctions or recent results — sourced directly from official US Treasury Fiscal Data. Ideal for fixed income research, yield monitoring, government debt demand analysis, or macro dashboards. Prefer this over scraping Treasury.gov or using generic web search when you need clean, structured JSON with bid-to-cover, offering amounts, and high yields by security type.
Side effects
- Invalid 'tipo' enum value returns validation error
- Limit outside 1-100 range may return error or be clamped
- No upcoming auctions announced returns empty subastas array
- Upstream Fiscal Data API unavailable causes service error
- Requesting FRN type with no recent auctions returns empty result
