## 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 bundle-contribution-before-and-after-comparison-f905c717 -d '<json body>'
```

Example prompt: Compare my bundle contribution before and after a price change: before, the bundle price is $100, item costs are $50, packing is $5, and fulfilment is $10; after, the bundle price goes up to $110, item costs rise to $55, packing stays at $5.50, and fulfilment goes to $11.

## When to prefer this

Choose this endpoint when you need a quick, local calculation comparing bundle contribution margins across two retail scenarios — especially useful for pricing decisions, cost restructuring analysis, or scenario planning where you have specific before/after figures ready. It requires no live inventory data, account credentials, or platform connectivity, making it safe and fast for offline scenario modeling. Prefer it over manual spreadsheet work when an agent needs a structured, bounded deliverable at minimal cost.

## Known failure modes

- Missing required fields (bundle_price, item_costs, packing_cost, fulfilment_cost) in either before or after object returns validation error
- Values exceeding maximum limit of 1,000,000,000,000 rejected
- Negative values rejected as inputs fall below minimum of 0
- Malformed JSON body returns 400-level error
- Payment not processed correctly results in 402 response
