## 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-iqr-outlier-flags-588fb7a6 -d '<json body>'
```

Example prompt: Flag any IQR outliers in my marketing contribution return data — I have four rows: spend $5000/contribution $8000, spend $5500/contribution $8800, spend $5000/contribution $8000, and spend $5500/contribution $8800. Give me the outlier flags with the formula and units used.

## When to prefer this

Choose this endpoint when you need fast, bounded IQR-based outlier flagging specifically on marketing contribution return data (spend vs. attributed contribution pairs) and want the formula, units, and limitations documented in the response. It is not a fraud-detection or financial-advice tool — use it for statistical data quality review of up to 200 marketing records per call at low cost ($0.01 USDC).

## Known failure modes

- Fewer than 2 rows submitted — minimum input not met
- marketing_spend is zero or negative — exclusiveMinimum constraint violated
- Row count exceeds 200 — maxItems limit breached
- Missing required fields (marketing_spend or attributed_contribution) in one or more rows
- Values outside allowed numeric range (±1,000,000,000,000) rejected
- Malformed JSON body returns validation error
