# Price Index Inflation Rate – One-Input Sensitivity Table

> Price Index Inflation Rate – One-Input Sensitivity Table is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Varies one input (current_index or previous_index) across up to 50 values to compute a sensitivity table of price index inflation rates.

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 price-index-inflation-rate-one-input-sensitivity-table-4b01366c -d '<json body>'
```

Example prompt: Give me a one-input sensitivity table for the price index inflation rate — hold the previous index fixed at 100 and vary the current index across these values: 95, 100, 105, 110, 115, 120, 125.

## When to prefer this

Choose this endpoint when you need to understand how the price index inflation rate responds to a range of one specific input while keeping all other parameters constant — ideal for scenario planning, break-even analysis, or presenting a sweep of outcomes to a stakeholder. It is more efficient than calling a single-calculation endpoint repeatedly when you have up to 50 test values ready.

## Known failure modes

- More than 50 values supplied in the values array — rejected due to maxItems constraint
- Zero or negative values for current_index or previous_index — rejected due to exclusiveMinimum:0
- Values outside the allowed range of -1e12 to 1e12 — rejected with validation error
- Missing or invalid field selector not in enum [current_index, previous_index] — schema validation failure
- Empty values array (minItems:1 not met) — request rejected

## How this service works

Price index inflation rate - One-input sensitivity table: Vary one declared input across up to 50 supplied values while holding other inputs fixed. Metric: Price index inflation 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 one-input sensitivity table report.

## Output

A JSON object containing a sensitivity table with one row per supplied input value, showing the computed price index inflation rate for each scenario, along with the formula used, units, and noted limitations of the calculation.
