## 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-gdp-year-over-year-growth-rate-fred-9f0c8310
```

Example prompt: What's the latest US GDP year-over-year growth rate from FRED — is the economy expanding or contracting right now?

## When to prefer this

Choose this endpoint when you need a simple, single-call lookup for the US GDP year-over-year growth rate without building a FRED API integration yourself. It is ideal for macro dashboards, economic briefings, or agent workflows that need a quick GDP data point at minimal cost ($0.01 USDC). Prefer it over raw FRED API access when you want a pre-processed, ready-to-use growth rate figure rather than raw series data requiring further calculation.

## Known failure modes

- FRED data source temporarily unavailable — upstream fetch failure
- Payment not completed (x402 payment required, $0.01 USDC) — returns 402 status
- Rate limiting or worker timeout on the Cloudflare edge function
- Stale or delayed data if FRED has not yet published the latest GDP revision
