## 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-real-gdp-growth-bea-9751dce7
```

Example prompt: What's the latest US real GDP growth print from the BEA — did it beat expectations, and how does the first release compare to the revised number?

## When to prefer this

Choose this endpoint when you need a structured, agent-ready GDP data package that goes beyond raw FRED numbers — specifically when you need first-release vs revised comparison, a quantified surprise metric with labeled expectation source, and the next release date all in one call. Prefer this over direct FRED API calls when surprise analysis or revision tracking is the goal, or when you want prediction-market-linked expectations rather than purely statistical baselines.

## Known failure modes

- FRED/ALFRED data temporarily unavailable — may return stale or partial data
- No matching prediction market exists — expectation_source falls back to trend-model
- Data not yet released for current quarter — latest_print reflects prior quarter
- Upstream BEA revision delay — revised flag may lag actual BEA revision schedule
- Payment not processed — x402 payment required before data is returned

## How this service works

Real GDP growth (BEA, quarterly): latest print, revisions, surprise — Latest Real GDP growth print from the BEA 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 quarterly release date, and a 12-observation mini-series.…

## Output

A JSON object containing: the FRED series ID and metadata (title, units, frequency, source agency, release name); the latest print object with observation date, headline value, first-release value, latest revised value, and a revised boolean flag; a surprise object with actual, expected, surprise delta, expectation source (market-implied or trend-model), expectation detail, and optional comparable prediction market info; the next quarterly release date; a 12-observation recent mini-series array; and a revisions array comparing first vs latest values by observation date.
