# Mining Operating Contribution Margin — Named Scenario Comparison

> Mining Operating Contribution Margin — Named Scenario Comparison 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).

Compares named what-if scenarios for mining operating contribution margin, computing the margin rate for each against a baseline using supplied revenue and contribution figures.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-named-scenario-comparison-84c26234 -d '<json body>'
```

Example prompt: Compare two mining margin scenarios for me: baseline revenue is $500,000 with a contribution of $120,000, and I want to see what happens under a scenario called 'Cost Reduction' where the contribution goes up to $145,000 — give me the margin rate comparison report.

## When to prefer this

Use this endpoint when you need a quick, formula-driven comparison of named what-if scenarios for mining operating contribution margin rate, and you already have revenue and contribution figures ready. It is ideal for structured scenario planning where you want labeled results (e.g. 'Optimistic', 'Cost Reduction') rather than a single-point calculation. Prefer alternatives if you need live price feeds, real-time mining data ingestion, or guaranteed return projections.

## Known failure modes

- Missing or zero revenue_usd in baseline causes validation error (revenue must be > 0)
- Scenarios array empty or missing causes schema rejection (minItems: 1)
- Scenario overrides object has no properties (minProperties: 1 required)
- Extremely large values near maximum bounds may cause precision issues
- Payment failure (0.01 USDC not settled) results in 402 response and no report

## How this service works

Mining operating contribution margin — Named scenario comparison: Named scenario comparison 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 named scenario comparison report.

## Output

A bounded named scenario comparison report showing the operating contribution margin rate (contribution divided by revenue) for the baseline and each named scenario, with labels identifying each scenario. No live prices or guaranteed returns are included — only formula-based computation on the supplied figures.
