## 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 synthora-us-treasury-securities-auctions-query-760d3cef -d '<json body>'
```

Example prompt: Pull the most recent US Treasury auction records from FiscalData — filter for 10-year notes, sorted by auction date descending, and show me the CUSIP, high yield, and bid-to-cover for each.

## When to prefer this

Choose this endpoint when you need structured, machine-readable US Treasury auction data (CUSIP, yield, bid-to-cover) for primary market analysis, trading pipelines, or auction calendar bots — especially when building autonomous agents that track Treasury supply without managing FiscalData API credentials directly. Prefer this over manual FiscalData queries when you need a simple $0.01-per-call keyless JSON interface with filtering and sorting built in.

## Known failure modes

- Invalid filter syntax returns an error or empty result set
- Unsupported sort field may return unordered or error response
- Page number beyond available records returns empty result
- FiscalData upstream outage causes delayed or failed response
- Malformed request body returns a non-ok response with no data

## How this service works

Upcoming and recent US Treasury auction records (CUSIP, security type/term, auction/issue/maturity dates, high yield, bid-to-cover) from FiscalData (keyless JSON). Powers autonomous primary-market agents, bill/note/bond calendar bots, and agent-to-agent trading pipelines tracking Treasury supply. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.

## Output

A JSON response with an 'ok' flag, a niche identifier ('us-treasury-securities-auctions'), and a result object containing paginated auction records from FiscalData — each record includes CUSIP, security type, security term, auction date, issue date, maturity date, high yield, and bid-to-cover ratio.
