## 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-ad-cost-per-order-before-after-comparison-fb9d9a4f -d '<json body>'
```

Example prompt: Compare my break-even ad cost per order before and after a cost change: before, my order revenue is $100, product cost $40, fulfilment $10, payment fees $5, and other variable costs $5; after, revenue is $110, product cost $44, fulfilment $11, payment fees $5.50, and other variable costs $5.50.

## When to prefer this

Use this endpoint when you need a quick, local, scenario-based comparison of the maximum affordable ad spend per order across two retail cost/revenue configurations — ideal for modelling the impact of cost changes, price adjustments, or fulfilment switches without needing live platform data or account access.

## Known failure modes

- Missing required fields (order_revenue, product_cost, fulfilment_cost, payment_fees, other_variable_costs) in either before or after object returns a validation error
- Negative or non-numeric values may be rejected or produce nonsensical results
- If total costs exceed revenue in either scenario, break-even ad cost will be zero or negative, indicating no ad budget headroom
- Payment failure (x402) results in no computation being returned

## How this service works

Break-even ad cost per order - Before and after comparison: Before and after comparison for Break-even ad cost per order. Supplied retail figures only. Local calculation and scenario analysis; no live inventory, account access, platform fee lookup or order execution. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded before and after comparison deliverable.

## Output

Returns two computed break-even ad cost per order values — one for the 'before' scenario and one for the 'after' scenario — along with a comparison showing the change, all derived from the supplied revenue and cost figures via local calculation.
