# Mining Operating Contribution Margin — Rolling Mean Report

> Mining Operating Contribution Margin — Rolling Mean Report is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Computes a rolling mean of mining operating contribution margin ratios (contribution_usd / revenue_usd) over a sliding window across a series of time-period rows.

## 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-rolling-mean-report-c5fa3bbf -d '<json body>'
```

Example prompt: I have 6 quarters of mining revenue and contribution figures — can you calculate the rolling mean of the contribution margin rate using a window of 3 periods? Revenues are 100, 110, 105, 120, 115, 130 and contributions are 25, 27.5, 26, 30, 28.75, 32.5.

## When to prefer this

Choose this endpoint when you need a statistically smoothed view of mining operating contribution margin rates over time using a rolling mean, particularly when raw period-to-period figures are volatile and you want to identify underlying trends. Ideal for mining-specific financial analytics where the contribution margin formula and assumptions are fixed and you supply raw revenue and contribution figures per period. At $0.01 USDC per call it is cost-effective for frequent periodic reporting.

## Known failure modes

- Fewer than 2 rows supplied — minimum of 2 rows required
- Window size larger than the number of rows provided — rolling mean cannot be computed
- revenue_usd is zero or negative — excluded by exclusiveMinimum constraint
- More than 200 rows supplied — exceeds maxItems limit
- Window integer outside 2–200 range — schema validation failure
- Malformed row objects missing required contribution_usd or revenue_usd fields

## How this service works

Mining operating contribution margin — Rolling mean report: Rolling mean report for Mining operating contribution margin. Supplied mining assumptions only; formula and units disclosed. No live prices, mining or guaranteed return. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded rolling mean report report.

## Output

A rolling mean report containing the smoothed contribution margin rates (contribution_usd / revenue_usd) computed over the specified sliding window across the supplied period rows. Each output data point represents the mean margin ratio over the preceding N periods as defined by the window parameter. No live prices or guaranteed returns are included — the report applies only the supplied mining assumptions with formula and units disclosed.
