## 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-federal-budget-monthly-data-monthly-treasury-statement-ef412968 -d '<json body>'
```

Example prompt: Pull the last 18 months of US federal budget data from the Monthly Treasury Statement — I want to see monthly receipts, outlays, and the deficit or surplus for each month, plus the trailing 12-month deficit total.

## When to prefer this

Use this endpoint when you need structured, machine-readable US federal budget data (receipts, outlays, deficit/surplus) sourced directly from the Monthly Treasury Statement without scraping Treasury websites. It is ideal for agents performing fiscal analysis, building dashboards, or monitoring US government financial health over time. Prefer this over general web search when you need clean numeric time-series data going back up to 36 months.

## Known failure modes

- Invalid meses value outside 1-36 range may return an error or default behavior
- Data lag: the most recent month's data may not be available immediately after month-end as the Treasury releases MTS reports with a delay
- Network or upstream Treasury data unavailability may cause empty or null series fields
- Missing or malformed request body may return a schema validation error
