## 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`):

```

Example prompt: Compare my marketplace net proceeds across two adjacent periods: first period had gross sales of $100, 10% fee, $1 fixed fee, and $5 refunds; second period had gross sales of $110, 11% fee, $1.10 fixed fee, and $5.50 refunds — show me the period-over-period change in net proceeds.

## When to prefer this

Choose this endpoint when you need a lightweight, local computation of marketplace net proceeds across consecutive periods without requiring live platform API access, account credentials, or real-time inventory data. Ideal for scenario modeling, fee sensitivity analysis, and period-over-period financial reporting on retail marketplace sales using only supplied numeric figures.

## Known failure modes

- Missing required fields (gross_sale, fee_percent, fixed_fee, refunds) returns validation error
- Array with fewer than 2 rows rejected (minItems: 2)
- Values exceeding maximum (1e12) cause schema validation failure
- fee_percent above 100 is rejected
- Non-numeric values in numeric fields cause parse errors
- Empty or malformed rows array returns 400-level error
