# Unemployment Rate Adjacent Period Changes Calculator

> Unemployment Rate Adjacent Period Changes Calculator 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).

Computes adjacent-observation differences and percent changes in unemployment rate across a supplied sequence of time periods, returning formula, units, and limitations with no interpolation.

## 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-adjacent-period-changes-calculator-d17fb90d -d '<json body>'
```

Example prompt: Can you calculate the adjacent period changes in unemployment rate for these four observations — unemployed counts of 50, 55, 50, 55 against labour forces of 1000, 1100, 1000, 1100 — and show me the period-over-period differences and percent changes?

## When to prefer this

Choose this endpoint when you have a time-ordered sequence of raw unemployed and labour-force counts and need adjacent-period differences and percent changes in unemployment rate computed from those exact figures — no smoothing, interpolation, or live data feeds. Ideal for economists, policy analysts, or automated reporting pipelines comparing discrete reporting periods (e.g. monthly, quarterly, annual) using only supplied data.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 rows required for any adjacent comparison
- Labour force value of zero — labour_force has exclusiveMinimum of 0 to prevent division by zero
- More than 200 rows supplied — exceeds maxItems limit
- Missing required fields unemployed or labour_force in any row — schema validation error
- Negative unemployed or labour_force values — minimum is 0
- Payment not included or insufficient — x402 payment of 0.01 USDC required per call

## How this service works

Unemployment rate - Adjacent period changes: Report adjacent-observation differences and eligible percent changes; no interpolation. Metric: Unemployment rate. Supplied figures only; returns JSON with formula, units and limitations. One of 50 calculators with 20 analysis modes. No live feed, financial advice or trade execution. 0.01 USDC includes one bounded adjacent period changes report.

## Output

A JSON response containing the computed adjacent-period unemployment rate differences and eligible percent changes for each consecutive pair of input rows, along with the formula used, units of measurement, and stated limitations — no interpolation applied, only differences between directly supplied observations.
