## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-data-desk-us-treasury-auctions-fa7d6727
```

Example prompt: Pull the last 5 US Treasury Note auction results — I want to see the high yield, bid-to-cover ratio, and offering size for each.

## When to prefer this

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.

## Known failure modes

- 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
