# Mining Fleet Spare Coverage — Before and After Comparison

> Mining Fleet Spare Coverage — Before and After Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Computes and compares spare coverage ratios for a mining fleet before and after a configuration change, given spare and operating unit counts.

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-fleet-spare-coverage-before-and-after-comparison-985aff17 -d '<json body>'
```

Example prompt: Compare my mining fleet spare coverage before and after a fleet expansion — before I had 5 spare units out of 100 operating units, and after I'll have 5.5 spares out of 110 operating units. Give me the before and after report.

## When to prefer this

Use this endpoint when you need a structured, formulaic before-and-after comparison of spare coverage ratios for a mining fleet with user-supplied unit counts. It is ideal for operations analysts or fleet managers evaluating the impact of scaling decisions without needing live pricing data. Prefer this over single-point calculators when a delta or change analysis between two fleet configurations is specifically required.

## Known failure modes

- operating_units set to zero causes division error (exclusiveMinimum enforced)
- missing required nested fields (spare_units or operating_units) in before or after objects returns validation error
- values exceeding the very large maximum bound may cause unexpected behavior
- non-numeric inputs for unit counts will fail schema validation

## How this service works

Mining fleet spare coverage — Before and after comparison: Before and after comparison 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 before and after comparison report.

## Output

A bounded before-and-after comparison report showing the spare coverage ratio for both the before and after fleet configurations, with the formula and units disclosed. No live pricing, mining profitability, or guaranteed return figures are included.
