## 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 x402stock-fred-macro-series-lookup-1ca55be2
```

Example prompt: What is the current VIX level and how has it changed recently? Pull the latest data from the FRED macro series.

## When to prefer this

Choose this endpoint when you need fast, agent-ready access to key Federal Reserve macro signal series without having to query FRED directly, parse raw XML/JSON, or manage API keys. It is ideal when you need a small set of canonical macro risk indicators (credit spreads, yield curve, VIX, inflation expectations, recession probability) alongside computed change and history fields ready for immediate use by an AI agent. Prefer it over raw FRED API calls when you want pre-computed deltas and YoY changes in a single call.

## Known failure modes

- Invalid series slug returns an error — only the 12 enumerated slugs (vix, yield-curve-10y-2y, yield-curve-10y-3m, high-yield-spread, ig-spread, breakeven-10y, real-yield-10y, jobless-claims, consumer-sentiment, mortgage-30y, financial-conditions, recession-probability) are supported
- FRED data lag — some series update weekly or monthly, so 'latest' may not be today's figure
- Payment failure — if the $0.01 USDC x402 payment is not processed, the request is rejected
- Network timeout if the upstream FRED data source is slow or unavailable

## How this service works

Pull a key market-signal macro series from the Federal Reserve (FRED) by slug: vix, yield-curve-10y-2y, yield-curve-10y-3m, high-yield-spread, ig-spread, breakeven-10y, real-yield-10y, jobless-claims, consumer-sentiment, mortgage-30y, financial-conditions, recession-probability. Each returns the latest value, prior, change, year-over-year, and recent history. No ticker needed. From x402stock

## Output
