## 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 x402-factory-building-permits-economic-data-3ac9324a
```

Example prompt: What's the latest US building permits print — did it surprise versus expectations, has it been revised from the first release, and when is the next one due?

## When to prefer this

Choose this endpoint when you need a self-contained, structured view of the US building permits economic release — combining the first-print vs revised value distinction, an economic surprise calculation, and the next release date in a single call. Prefer it over raw FRED API when you also want surprise analytics and revision tracking without building that logic yourself. It is particularly useful for macro dashboards, economic calendars, or agents reacting to housing-sector data releases.

## Known failure modes

- FRED/ALFRED upstream outage — endpoint may return 503 or stale data
- No surprise value if the release date hasn't occurred yet — surprise field returns null
- Missing prediction market — expectation_source falls back to trend-model
- Payment not completed via x402 protocol — returns 402 Payment Required
- Rate limit or quota exceeded — returns 429

## How this service works

Building permits (Census, monthly): latest print, revisions, surprise — Latest Building permits print from the Census via FRED/ALFRED: first-release vs latest value with a revised flag (revisions never pose as print-day numbers), surprise vs a labeled expectation (market-implied when a matching prediction market exists, else trend-model), next monthly release date, and a 12-observation…

## Output

A JSON object with the series ID and title, latest print (obs_date, headline value, units, basis, first-release value, latest revised value, revised flag), surprise object (actual, expected, surprise delta, expectation source — market-implied or trend-model — and optional prediction market details), next release date, a 12-observation recent mini-series array, and a revisions array showing first vs latest values per observation date.
