# Disposable-Income Saving Rate Named Scenario Comparison

> Disposable-Income Saving Rate 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 2026-10-22).

Applies up to 20 named override scenarios to a baseline disposable income and outlays and returns a JSON comparison of saving rates across all scenarios.

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 disposable-income-saving-rate-named-scenario-comparison-68691c68 -d '<json body>'
```

Example prompt: Compare saving rates across three scenarios for me: baseline is $10,000 disposable income and $8,000 outlays. Scenario 1 'Raise' bumps income to $12,000, Scenario 2 'Cost Cut' drops outlays to $6,500, and Scenario 3 'Both' sets income to $12,000 and outlays to $6,500.

## When to prefer this

Choose this endpoint when you need to evaluate multiple named what-if configurations of disposable income and outlays simultaneously and compare their saving rates against a single baseline — especially when you want labeled, structured JSON output with formula and limitations included. Prefer it over a single-calculation endpoint when you have 2–20 distinct scenarios to compare in one call, or when audit-ready labeling of each scenario is important for reporting or planning workflows.

## Known failure modes

- Missing or zero disposable_income in baseline triggers validation error (exclusiveMinimum:0)
- Scenarios array with zero items or more than 20 items rejected
- Overrides object with no properties (minProperties:1) causes rejection
- Values exceeding 1,000,000,000,000 are out of range
- Malformed JSON body returns 400-level error
- Payment not included or insufficient USDC results in 402 Payment Required

## How this service works

Disposable-income saving rate - Named scenario comparison: Apply up to 20 explicit input-override scenarios to one baseline and report their differences. Metric: Disposable-income saving 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 named scenario comparison report.

## Output

A JSON object containing the baseline saving rate, each named scenario's saving rate (computed as (disposable_income - outlays) / disposable_income), the difference versus baseline for each scenario, along with the formula used, units, and stated limitations of the calculation.
