## 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 marketing-contribution-return-named-scenario-comparison-ddf3919e -d '<json body>'
```

Example prompt: Compare my baseline marketing scenario — $5,000 spend with $8,000 attributed contribution — against two named alternatives: 'Budget Cut' with $3,500 spend and $6,200 contribution, and 'Scale Up' with $9,000 spend and $14,000 contribution, and show me the differences in marketing contribution return for each.

## When to prefer this

Choose this endpoint when you need to evaluate multiple named what-if scenarios against a single marketing contribution return baseline in one call, rather than making separate single-calculation calls. It is ideal for sensitivity analysis, budget planning, and side-by-side comparison of up to 20 distinct marketing investment strategies.

## Known failure modes

- Missing required baseline fields (marketing_spend or attributed_contribution) returns validation error
- marketing_spend of zero or negative value is rejected due to exclusiveMinimum constraint
- More than 20 scenarios submitted exceeds maxItems limit
- Scenario overrides object with no properties fails minProperties:1 constraint
- Mismatched currency or reporting periods in inputs produce mathematically valid but meaningless results (not caught by API)
