# Break-even Sales Units – Weighted Result Mean

> Break-even Sales Units – Weighted Result Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Computes a weighted mean of break-even sales unit values across up to 200 supplied scenarios, returning the formula, units, and limitations in JSON.

## 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 break-even-sales-units-weighted-result-mean-8c36ae45 -d '<json body>'
```

Example prompt: I have four product scenarios with different fixed costs, unit prices, and variable costs — can you calculate the weighted mean break-even sales units using weights of 1, 2, 1, and 2? Scenario 1: fixed costs $5000, unit price $20, variable cost $12. Scenario 2: fixed costs $5500, unit price $22, variable cost $13.20. Scenario 3: same as Scenario 1. Scenario 4: same as Scenario 2.

## When to prefer this

Choose this endpoint when you need to aggregate multiple break-even unit calculations into a single representative figure using non-uniform weights — for example when scenarios have different probabilities, market sizes, or importance levels. It is not a pooled accounting ratio and does not access live financial data, so it is best suited for offline scenario analysis and sensitivity studies.

## Known failure modes

- Fewer than 2 rows or weights supplied — minimum 2 items required
- Mismatched array lengths between rows and weights
- Unit price of zero or below — excluded by exclusiveMinimum constraint
- Values exceeding the maximum of 1,000,000,000,000 — rejected
- Variable cost per unit equal to or exceeding unit price — results in undefined or infinite break-even units
- Payment failure — endpoint requires 0.01 USDC via x402 protocol

## How this service works

Break-even sales units - Weighted result mean: Calculate a mean of up to 200 results using supplied nonnegative weights; not a pooled accounting ratio. Metric: Break-even sales units. 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 weighted result mean report.

## Output

A JSON object containing the weighted mean break-even sales units computed from the supplied rows and weights, along with the formula used, measurement units, and stated limitations of the calculation.
