## 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-gold-reserves-lookup-d4ac9eff -d '<json body>'
```

Example prompt: Pull the latest US Treasury gold reserve data for each storage facility — I want to see the location, how many fine troy ounces are held there, and the book value.

## When to prefer this

Choose this endpoint when you need official, government-sourced US Treasury gold reserve data broken down by storage facility without managing an API key. It is ideal for agents tracking sovereign gold holdings, macroeconomic research, or monitoring changes in US gold stockpiles. Prefer this over scraping Treasury websites or building direct integrations with FiscalData, especially in agentic workflows that already handle x402 micropayments.

## Known failure modes

- Payment failure (402) if USDC payment is not properly attached
- Upstream Treasury FiscalData service unavailable causing proxy to return 5xx
- Empty or stale dataset if Treasury has not published new records recently
- Malformed POST body resulting in 400 bad request
- Network timeout if the upstream fiscal data API is slow to respond

## How this service works

## Output

Returns a list of records for each US Treasury gold storage facility, including the facility name/location, the quantity of gold in fine troy ounces, and the official book value in USD, sourced from the latest available Treasury FiscalData records.
