## 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 marketplace-proceeds-waterfall-sequential-input-change-attribution-25d75fab -d '<json body>'
```

Example prompt: Can you do a sequential waterfall attribution showing how each input change contributed to the difference in my marketplace net proceeds? Before: gross sale $100, fee 10%, fixed fee $1, refunds $5. After: gross sale $110, fee 11%, fixed fee $1.10, refunds $5.50.

## When to prefer this

Choose this endpoint when you need to understand not just the total change in marketplace net proceeds, but how each individual input variable sequentially contributed to that change — a classic waterfall/bridge chart decomposition. It is a local, offline calculation requiring no live platform connection, making it ideal for scenario planning, financial reporting, or explaining payout differences to stakeholders.

## Known failure modes

- Missing required fields in before or after objects returns validation error
- Values outside allowed range (e.g. fee_percent > 100, negatives) rejected
- Malformed JSON body returns 400-level error
- Service unavailable returns 5xx; retry recommended
- Payment failure or insufficient USDC balance blocks request

## Output

A sequential (waterfall) attribution report breaking down how each individual input change (gross_sale, fee_percent, fixed_fee, refunds) contributed to the total difference in net marketplace proceeds between the 'before' and 'after' scenarios, showing the step-by-step incremental impact of each variable.
