Treasury auction and yields API

One call for a US rates snapshot: Treasury par curve with 2s10s, 3m10y and 5s30s and their changes, upcoming Treasury auctions with ET close times, and recent results with bid-to-cover and dealer share versus prior auctions.

Agents that touch rates, futures or macro need three things before the session: where the curve is, which Treasury auctions are coming, and how the last ones went. GET /rates/treasury-desk packs all three into one response, with a three-line headline you can drop straight into a prompt.

What you get

Curve: the Treasury daily par yield curve from 1 month to 30 years, the 2s10s, 3m10y, 2s5s and 5s30s spreads, a shape label (normal, flat or inverted on 2s10s), and 1-day, 1-week and 1-month changes in basis points for every tenor and spread.
Upcoming auctions (default next 14 days): security, CUSIP, offering size, ET close time and minutes to close. Reopenings are labeled with both terms, for example 10-Year TIPS (reopening, 9-Year 8-Month). Auctions that are scheduled but not yet announced are flagged announced: false.
Recent results (default last 6): high yield, bid-to-cover, the share taken by indirect bidders, direct bidders and primary dealers, the averages of the prior six auctions of the same security, and a demand label: weak if bid-to-cover is 0.10 or more below that average or the dealer share is 5 points or more above it, strong if bid-to-cover is 0.10 or more above with no higher dealer share, otherwise average.

Price and payment

$0.01 per call over x402, in USDC on Base or Solana. A bad parameter gets a 400 before any payment. The route is also a tool called treasury_desk on the remote MCP server. Auctions also appear as events in the session brief and the event-risk gate.

Sources and limits

All data is from the US Treasury: the daily par yield curve (end of day, not published on bond-market holidays), TreasuryDirect auction announcements and results, and Treasury Fiscal Data as a fallback. The demand label is a simple comparison with past auctions, not a when-issued tail. Nothing here is investment advice.
