## 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 us-treasury-auction-results-calendar-5be7a4da
```

Example prompt: Pull the last 180 days of US Treasury 10-Year Note auction results from TreasuryDirect and show me the bid-to-cover trend, indirect-bidder share, and upcoming auction calendar.

## When to prefer this

Choose this endpoint when you need normalized, signal-enriched US Treasury auction data with computed analytics (bid-to-cover trend, indirect-bidder share) rather than raw data from TreasuryDirect. Ideal for fixed income research, macro analysis, and monitoring government debt demand without building your own data pipeline from TreasuryDirect.

## Known failure modes

- Invalid or unsupported security type returns a validation error
- Days parameter out of range (1-3660) returns a schema error
- TreasuryDirect data unavailable or delayed may result in incomplete results or stale data
- No auctions found for the given type/term/days combination returns an empty list
- Network timeout from upstream TreasuryDirect source

## How this service works

US Treasury auction results plus the upcoming calendar from TreasuryDirect. Returns a normalized list of recent auctions for a security type with computed signals: bid-to-cover trend, indirect-bidder share and average cover. Each auction is cited with its CUSIP, auction date and source.

## Output

Returns a normalized list of Treasury auction records, each with CUSIP, auction date, security type/term, bid-to-cover ratio, indirect-bidder share, and source citation. Also includes computed signals: bid-to-cover trend, average cover across the lookback window, and optionally the upcoming auction calendar entries from TreasuryDirect.
