# Mining Fleet Spare Coverage — Distribution Histogram

> Mining Fleet Spare Coverage — Distribution Histogram 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).

Generates a distribution histogram showing the spread of spare-to-operating unit coverage ratios across a fleet of mining operations.

## 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-fleet-spare-coverage-distribution-histogram-493acc64 -d '<json body>'
```

Example prompt: Give me a distribution histogram across 10 bins for my mining fleet: Site A has 8 spares and 120 operating units, Site B has 5 spares and 100 units, Site C has 12 spares and 150 units, and Site D has 3 spares and 80 units — I want to see how spare coverage is spread across these operations.

## When to prefer this

Choose this endpoint when you need a statistical frequency distribution of spare coverage ratios across a mining fleet — specifically when you want to see how spare-to-operating unit ratios cluster across multiple sites rather than a single calculation. Prefer this over single-calculation endpoints when you have 2–200 fleet rows and want histogram binning with configurable bucket counts. Best suited for fleet-level analysis, audit preparation, or benchmarking spare coverage spread.

## Known failure modes

- Fewer than 2 rows supplied — minimum row count not met
- bins value exceeds maximum of 30 or is less than 1
- operating_units is zero or negative — exclusiveMinimum violation
- spare_units or operating_units exceed maximum allowed value
- More than 200 rows supplied — maxItems exceeded
- Malformed row objects missing required spare_units or operating_units fields
- Payment not attached or insufficient — x402 payment required

## How this service works

Mining fleet spare coverage — Distribution histogram: Distribution histogram for Mining fleet spare coverage. 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

Returns a bounded distribution histogram report showing how spare coverage ratios (spare_units / operating_units) are distributed across the supplied fleet rows, bucketed into the specified number of bins. Includes bin boundaries, frequency counts per bin, and summary statistics — based solely on supplied mining assumptions with disclosed formula and units. No live prices or guaranteed returns.
