## 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-u-s-treasury-yield-ad19b294
```

Example prompt: What is the current 10-year U.S. Treasury yield, and how does it compare to where it was a year ago? Pull the data in JSON format.

## When to prefer this

Choose this endpoint when you need authoritative, analytics-enriched 10-year U.S. Treasury yield data with pre-computed z-scores, percentile ranks, and trend signals — particularly for financial modeling, duration risk analysis, equity valuation, or macro research where context around the yield level matters as much as the raw number. Prefer this over raw FRED data pulls when you want derived analytics out of the box without post-processing.

## Known failure modes

- Invalid date format returns an error — dates must be YYYY-MM-DD
- date_from after date_to returns empty or error response
- Requesting future dates returns no data
- Invalid fmt enum value may cause a bad request error
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Benchmark long-term U.S. government borrowing rate. Anchors mortgage rates, corporate bond yields, and equity discount rates. Widely used as the risk-free rate in financial models. Critical for duration risk, equity valuation, and global capital flow analysis. Daily frequency, 60+ year history.

## Output

Returns an array of daily observations, each containing the date, raw yield value, month-over-month and year-over-year absolute and percentage changes, 12-month and 5-year z-scores, 5-year percentile rank, 3-month and 12-month rolling averages, and a flag indicating whether the yield is above the long-run trend.
