# Inflation-Adjusted Purchasing Value – Named Scenario Comparison

> Inflation-Adjusted Purchasing Value – Named Scenario Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-27).

Applies up to 20 named override scenarios to a baseline inflation-adjusted purchasing value calculation and returns a comparative JSON report with formula, units, and limitations.

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 inflation-adjusted-purchasing-value-named-scenario-comparison-613811f1 -d '<json body>'
```

Example prompt: Compare the inflation-adjusted purchasing value of $12,000 against three named scenarios: 'Low Inflation' with current price index 110, 'Base Case' with current price index 120, and 'High Inflation' with current price index 140 — all starting from a base price index of 100.

## When to prefer this

Choose this endpoint when you need to compare inflation-adjusted purchasing value across multiple named what-if scenarios simultaneously rather than computing a single result — ideal for scenario planning, sensitivity analysis, or presenting decision-makers with labeled alternatives. It is purpose-built for batch comparison (up to 20 scenarios) against one baseline and returns structured JSON suitable for downstream reporting. Prefer alternatives if you need live CPI data feeds, a single-point calculation, or financial advice.

## Known failure modes

- Missing required baseline fields (nominal_value, base_price_index, current_price_index) returns validation error
- base_price_index or current_price_index of zero or negative triggers exclusiveMinimum validation failure
- More than 20 scenarios in the array returns a maxItems validation error
- Scenario overrides object with no properties fails minProperties:1 requirement
- Nominal value exceeding ±1,000,000,000,000 triggers maximum/minimum validation error
- Empty or missing label string in a scenario item fails minLength:1 requirement

## How this service works

Inflation-adjusted purchasing value - Named scenario comparison: Apply up to 20 explicit input-override scenarios to one baseline and report their differences. Metric: Inflation-adjusted purchasing value. 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 named scenario comparison report.

## Output

A JSON object containing the inflation-adjusted purchasing value for the baseline and each named scenario, along with the formula used, measurement units, the difference between baseline and each scenario's real value, and stated limitations of the calculation.
