# Unemployment Rate Ordered Trend Analysis

> Unemployment Rate Ordered Trend Analysis is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Fits a descriptive straight-line (OLS) trend to a user-supplied series of unemployment rate observations (up to 200 equally spaced data points) and returns the trend formula, units, and limitations — no forecast.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 unemployment-rate-ordered-trend-analysis-a07e4175 -d '<json body>'
```

Example prompt: I have 12 quarterly unemployment observations — unemployed counts and labour force counts for each period — can you fit a straight-line trend to the unemployment rate and give me the formula and slope?

## When to prefer this

Choose this endpoint when you need a fast, bounded descriptive linear trend fit on a supplied unemployment rate series (2–200 equally spaced points) and want a structured JSON result with the formula and limitations. It is not a forecasting tool and does not pull live data, so prefer it when you already have historical observations and need a simple trend summary rather than a predictive model or real-time feed.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 observations required
- More than 200 rows supplied — exceeds maxItems limit
- labour_force value of zero — exclusiveMinimum violation causes validation error
- Non-numeric or missing unemployed/labour_force fields — schema validation failure
- unemployed exceeds maximum of 1,000,000,000,000 — out-of-range error
