## 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 delx-commerce-break-even-calculator-a010c869 -d '<json body>'
```

Example prompt: How many units do I need to sell to break even if my fixed costs are $10,000 and I make $8 contribution margin per unit?

## When to prefer this

Choose this endpoint when you need a fast, lightweight, pay-per-call break-even calculation without any signup or subscription. Ideal for AI agents that need on-demand financial computation embedded in workflows, especially when integrating with x402 crypto micropayment infrastructure on Base or Solana.

## Known failure modes

- Missing required field (fixed_cost or contribution_per_unit) returns an error
- contribution_per_unit of zero or negative makes break-even infeasible or causes division error
- Payment failure via x402 results in 402 Payment Required response
- Negative fixed_cost may produce nonsensical or negative break-even units

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object indicating whether break-even is feasible, the original fixed_cost, the contribution_per_unit, and the computed break_even_units (the number of units that must be sold to fully cover fixed costs).
