## 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-distribution-histogram-90678004 -d '<json body>'
```

Example prompt: Can you generate a 10-bin distribution histogram of our mining operating contribution margins? Here are 5 operations: operation 1 had revenue $500,000 and contribution $120,000; operation 2 had revenue $300,000 and contribution $45,000; operation 3 had revenue $800,000 and contribution $250,000; operation 4 had revenue $200,000 and contribution $-10,000; operation 5 had revenue $1,000,000 and contribution $400,000.

## When to prefer this

Choose this endpoint when you need a statistical frequency distribution of mining-specific operating contribution margin rates across multiple operations or time periods. It is purpose-built for mining financials with pre-configured assumptions for the mining domain, making it more appropriate than a generic histogram tool when the context is mining profitability analysis. Best suited for batch analysis of 2–200 mining operation records at low cost ($0.01 USDC per call).

## Known failure modes

- Fewer than 2 rows provided — minimum 2 rows required
- More than 200 rows submitted — exceeds maxItems limit
- revenue_usd is zero or negative — exclusiveMinimum constraint violated
- bins value exceeds 30 or is less than 1 — out of allowed range
- Missing required fields contribution_usd or revenue_usd in any row
- Malformed JSON payload — request rejected

## How this service works

Mining operating contribution margin — Distribution histogram: Distribution histogram 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 distribution histogram report.

## Output

A bounded distribution histogram report showing how mining operating contribution margin rates (contribution_usd / revenue_usd) are distributed across the requested number of bins, including bin boundaries and frequency counts for each bin.
