# Break-even Sales Units Ordered Trend Analysis

> Break-even Sales Units Ordered Trend Analysis is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-14).

Fits a descriptive straight-line trend to a time-ordered series of break-even sales unit observations (up to 200 data points) and returns the trend formula, units, and limitations.

## 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-ordered-trend-analysis-dc321a49 -d '<json body>'
```

Example prompt: Fit a straight-line trend to these 6 periods of break-even data and give me the formula: period 1 fixed costs $4000, price $18, variable cost $10; period 2 fixed costs $4200, price $18.50, variable cost $10.50; period 3 fixed costs $4400, price $19, variable cost $11; period 4 fixed costs $4600, price $19, variable cost $11.50; period 5 fixed costs $4800, price $20, variable cost $12; period 6 fixed costs $5000, price $20.50, variable cost $12.50.

## When to prefer this

Choose this endpoint when you need a descriptive linear trend fitted to a sequence of historically computed or supplied break-even unit values across up to 200 equally spaced periods. It is ideal for summarizing directional movement in break-even performance over time without requiring a forecast. Prefer it over single-point break-even calculators when trend direction and slope matter, and over forecasting endpoints when you only need to describe what has already occurred in the supplied data.

## Known failure modes

- Fewer than 2 rows supplied — minimum row count not met, returns validation error
- unit_price equals zero — division by zero in break-even formula, rejected by schema exclusiveMinimum constraint
- More than 200 rows supplied — exceeds maxItems limit, request rejected
- Negative or out-of-range values for fixed_costs or variable_cost_per_unit — schema validation failure
- variable_cost_per_unit equals or exceeds unit_price — contribution margin is zero or negative, break-even is undefined or infinite
- Malformed JSON body — request parsing error returned

## How this service works

Break-even sales units - Ordered trend analysis: Fit a descriptive straight-line trend to up to 200 equally spaced supplied observations; no forecast. 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 ordered trend analysis report.

## Output

A JSON object containing the fitted straight-line trend formula (slope and intercept), the computed break-even unit values for each supplied observation, a description of units used, and explicit limitations of the descriptive analysis (e.g., no forecast, no live data, confined to supplied observations only).
