## 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 stationfx-10-year-breakeven-inflation-rate-70e51ce8
```

Example prompt: Pull the 10-year breakeven inflation rate from StationFX for the past 6 months in JSON format, including z-scores and trend flags, so I can see whether inflation expectations are historically elevated right now.

## When to prefer this

Choose this endpoint when you need market-implied inflation expectations (not realized CPI) derived from Treasury-TIPS spreads, with precomputed derived metrics like z-scores, trend flags, and rolling averages. Prefer it over raw FRED data when you need analysis-ready inflation data without building your own derived metrics. Best suited for real rate models, inflation regime detection, and Fed policy analysis.

## Known failure modes

- Invalid date format returns a 400 error
- date_from after date_to returns empty data or an error
- Requesting fields that don't exist returns an error or omits those fields
- Dates beyond the available 20+ year history return empty arrays
- Network or payment failure (x402) returns a 402 Payment Required before data is delivered

## How this service works

Market-implied inflation expectation over the next 10 years, derived from the spread between nominal Treasury and TIPS yields. Primary input for real rate calculations, inflation regime detection, and Fed policy models. Rises when markets expect higher future inflation. Daily frequency, 20+ year history with full derived metrics.

## Output

Returns a JSON array of daily observations, each containing the raw breakeven rate value (in percent), month-over-month and year-over-year changes (absolute and percentage), trailing z-scores over 12-month and 5-year windows, a percentile rank over 5 years, a binary above-trend flag, and rolling 3-month and 12-month averages. History spans 20+ years.
