## 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-target-gap-calculator-f79033a8 -d '<json body>'
```

Example prompt: I sold an item for $250 on a marketplace, they charge 12% plus a $1.50 fixed fee, I had $8 in refunds, and I want to know how far my net proceeds are from my $200 target — can you calculate that gap for me?

## When to prefer this

Use this endpoint when you need a fast, local calculation of the gap between expected net marketplace proceeds and a target figure, given known fee structures. Ideal for scenario analysis and planning without needing live platform fee lookups or account access. Not suitable if you need real-time fee rates, live inventory data, or actual order execution.

## Known failure modes

- Missing required fields (gross_sale, fee_percent, fixed_fee, refunds) returns a validation error
- Values exceeding maximum bounds (e.g. gross_sale > 1 trillion) are rejected
- Non-numeric inputs for numeric fields cause schema validation failure
- Negative values for refunds, fixed_fee, or gross_sale (below minimum 0) are rejected
