## 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-record-ranking-0aa0fcee -d '<json body>'
```

Example prompt: Rank these 3 product scenarios by break-even sales units: Product A has fixed costs of $5000, unit price $20, variable cost $12; Product B has fixed costs $5500, unit price $22, variable cost $13.20; Product C has fixed costs $8000, unit price $30, variable cost $15.

## When to prefer this

Choose this endpoint when you need to rank multiple business scenarios, products, or configurations by their break-even sales volume in a single call. It is purpose-built for comparative break-even analysis across up to 200 records simultaneously, preserving row indices for traceability. Prefer this over a single break-even calculator when the user's goal is relative ranking or prioritization rather than a single calculation.

## Known failure modes

- Unit price equals variable cost per unit causes division by zero (zero or negative contribution margin)
- Fewer than 2 rows supplied returns validation error
- More than 200 rows supplied exceeds maximum limit
- Negative or zero unit price rejected by schema validation
- Missing required fields (fixed_costs, unit_price, variable_cost_per_unit) causes request rejection
- Payment failure or insufficient USDC balance returns 402 error
