## 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 vextorium-us-budget-deficit-59d24394 -d '<json body>'
```

Example prompt: Pull the US federal budget deficit data for the last 12 months — I want to see monthly revenue, expenses, and the running balance, plus the 12-month total deficit figure.

## When to prefer this

Choose this endpoint when you need official, U.S. Treasury-sourced monthly fiscal data (revenue, expenses, deficit/surplus) with minimal setup and pay-per-call pricing via USDC. Prefer it over web scraping or generic economic APIs when you need structured, machine-readable data with a citation, or when you need up to 36 months of historical monthly series in a single call.

## Known failure modes

- Invalid months value outside 1-36 range returns an error or default behavior
- Data may lag by one month if the Treasury Statement has not yet been published for the current month
- Network or payment authorization failure returns a 402 or 5xx error
- Malformed request body (wrong bodyType or missing required fields) returns a 400 error
