How this service works
US Treasury auctions results and calendar: upcoming and recent auctions with high yield, bid-to-cover, indirect and dealer shares, and the change vs the previous auction of the same security. Use to track Treasury supply and demand.
Output
A JSON object with two arrays: 'recent' (completed auctions with auction date, security term, security type, high yield percent, bid-to-cover ratio, indirect bidders percent, and delta vs prior auction of the same security) and 'upcoming' (scheduled future auctions with date, term, and type).
Example use cases
Macro research on Treasury demand trends
“Show me the most recent Treasury note and bill auction results — I need the high yields, bid-to-cover ratios, and how indirect bidder participation has changed compared to the previous auctions of the same security.”
Pre-trade bond market context check
“Before I position in Treasuries, can you check what the latest auction data looks like? I want to see if bid-to-cover ratios are improving or deteriorating and what indirect bidders are doing.”
Upcoming auction calendar monitoring
“What Treasury auctions are coming up? Give me the dates, security types, and terms so I can plan around any potential market-moving supply events.”
Technical details
Endpoint
GEThttps://api.marketintelligenceapi.com/api/v1/rates/auctions?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, parsed US Treasury auction metrics (yield, bid-to-cover, bidder composition) in a single call without scraping TreasuryDirect or manually parsing auction announcements. It is especially useful for agents doing macro bond market analysis, monitoring demand trends across auction cycles, or building pre-trade context around Treasury supply events.
Side effects
- No data available for a requested period — returns empty arrays
- Rate limit exceeded — HTTP 429 if call volume exceeds plan limits
- Payment failure — HTTP 402 if x402 payment is not processed correctly
- Stale data — auction calendar may lag official Treasury announcements by a short delay
