# Margin of Safety Base-100 Rebase Report

> Margin of Safety Base-100 Rebase Report 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).

Calculates margin of safety values for a series of actual vs break-even sales figures and rebases them to a base-100 index anchored at a specified observation.

## 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 margin-of-safety-base-100-rebase-report-edcb5740 -d '<json body>'
```

Example prompt: I have four quarterly periods: Q1 actual sales $10,000 and break-even $7,000; Q2 actual $11,000 and break-even $7,700; Q3 actual $10,000 and break-even $7,000; Q4 actual $11,000 and break-even $7,700 — can you rebase the margin of safety figures to a base-100 index anchored at the first observation?

## When to prefer this

Choose this endpoint when you need to normalize a series of margin of safety figures to a common baseline index (base-100) rather than viewing raw percentages, especially when comparing performance across periods or benchmarking against a specific reference point. It is ideal for time-series financial analysis where relative change from a base period is more informative than absolute values. Use it over a raw margin of safety calculator when stakeholders need an indexed view for trend charts or when you want to anchor performance to a specific quarter or year.

## Known failure modes

- Fewer than 2 rows supplied — violates minItems constraint
- actual_sales value of 0 — violates exclusiveMinimum constraint
- base_index out of range (≥ number of rows or > 199) — invalid reference period
- Extremely large values near the 1 trillion maximum may cause precision issues
- Missing required fields actual_sales or break_even_sales in any row — validation error
- break_even_sales equal to or exceeding actual_sales produces a zero or negative margin of safety which may distort the rebased index

## How this service works

Margin of safety - Base-100 rebase report: Rebase ordered calculated values against a supplied positive base observation. Metric: Margin of safety. 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 base-100 rebase report report.

## Output

Returns a JSON object containing the rebased margin of safety values for each supplied row, normalized so the specified base observation equals 100, along with the formula used, the units of measurement, and stated limitations of the calculation.
