# Break-even Sales Units – Two-Input Scenario Grid

> Break-even Sales Units – Two-Input Scenario Grid is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-23).

Calculates break-even sales units across a grid of up to 100 combinations of two chosen input variables (fixed costs, unit price, or variable cost per unit), reporting invalid combinations.

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 break-even-sales-units-two-input-scenario-grid-9f28571d -d '<json body>'
```

Example prompt: Run a break-even units scenario grid varying fixed_costs across [4000, 5000, 6000, 7000] and unit_price across [18, 20, 22, 24], using a baseline of fixed_costs=5000, unit_price=20, variable_cost_per_unit=12 — give me all the combinations and flag any invalid ones.

## When to prefer this

Choose this endpoint when you need to explore how break-even sales volume responds to simultaneous changes in two of the three core variables (fixed costs, unit price, variable cost per unit) across a structured grid of up to 100 scenarios. It is ideal for financial modeling, pricing decisions, and cost-structure stress testing where a two-dimensional sensitivity table is needed rather than a single calculation or a one-variable sweep.

## Known failure modes

- Invalid combination flagged (e.g. unit_price <= variable_cost_per_unit makes break-even undefined or infinite)
- field_x and field_y set to the same variable (duplicate axis error)
- values_x or values_y arrays exceed 10 items (maxItems constraint violation)
- Baseline object missing required fields (fixed_costs, unit_price, variable_cost_per_unit)
- Payment failure or insufficient USDC balance (x402 payment required)
- Numbers outside allowed range (0 to 1,000,000,000,000)

## How this service works

Break-even sales units - Two-input scenario grid: Calculate up to 100 combinations of two distinct supplied input fields, with invalid combinations reported. 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 two-input scenario grid report.

## Output

A JSON response containing the break-even sales units for each of the requested combinations of the two chosen input variables (up to 100 cells in the grid), the formula used, units, flags for any invalid combinations (e.g. where unit price does not exceed variable cost per unit), and stated limitations of the calculation.
