## 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 suverse-treasury-savings-bonds-proxy-ee3f3b20 -d '<json body>'
```

Example prompt: Pull the latest US savings bond data from Treasury FiscalData — I want to see the most recent series, issue amounts, and redemption figures for tracking retail government debt.

## When to prefer this

Choose this endpoint when you need retail US government savings bond data (series, issuance, redemptions) without managing a Treasury API key. Ideal for AI agents or pipelines that need quick, keyless access to the latest FiscalData savings bond records, especially when building financial dashboards, monitoring government debt metrics, or conducting fixed income research on retail Treasury instruments.

## Known failure modes

- Treasury FiscalData upstream service unavailable causing 502 or 503 response
- Payment of 0.002 USDC not provided or rejected resulting in 402 error
- Malformed POST body causing 400 bad request
- Rate limiting if too many calls are made in a short window
- Stale or delayed data if Treasury FiscalData has not updated recently

## How this service works

US savings bonds issued and redeemed from the official Treasury FiscalData service, no key, latest records. Returns series, issue amounts, and redemptions. For AI agents tracking retail government debt.

## Output

Returns structured records from the US Treasury FiscalData service including savings bond series identifiers (e.g. Series I, Series EE), total issue amounts in dollars, redemption amounts, and associated date metadata — all reflecting the latest available records with no authentication required.
