## 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 mining-operating-contribution-margin-iqr-outlier-flags-7e7dae58 -d '<json body>'
```

Example prompt: Can you check my mining operation data for contribution margin outliers? I have 10 rows of revenue and contribution figures — flag any that fall outside the IQR range.

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.01 USDC) statistical outlier check specifically on mining operating contribution margin rates using IQR methodology, with up to 200 rows, and you have revenue and contribution figures in USD. Best for mining finance analytics pipelines, pre-reporting data validation, or portfolio anomaly detection where live price feeds are not needed.

## Known failure modes

- Fewer than 2 rows provided — minimum 2 rows required
- revenue_usd set to zero or negative — exclusiveMinimum constraint violated
- More than 200 rows submitted — maxItems limit exceeded
- Missing required fields contribution_usd or revenue_usd in any row
- Malformed JSON body returns 400-level error
- Payment not included or insufficient — x402 payment required
