# Mining Fleet Spare Coverage — Weighted Result Mean

> Mining Fleet Spare Coverage — Weighted Result Mean 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 weighted mean of spare-unit coverage ratios across multiple mining fleet scenarios using user-supplied spare and operating unit counts with custom weights.

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-weighted-result-mean-911b40fd -d '<json body>'
```

Example prompt: Calculate the weighted mean spare coverage for my mining fleet: I have two site configurations — Site A with 5 spare units and 100 operating units (weight 1), and Site B with 8 spare units and 120 operating units (weight 3). What's the weighted result mean?

## When to prefer this

Choose this endpoint when you need a single weighted aggregate metric summarising spare-unit coverage ratios across multiple mining fleet configurations or sites, especially when different sites have different importance levels expressed as weights. Prefer this over a simple mean when site-level weighting is meaningful (e.g. larger or higher-priority sites should count more). Not suitable for real-time price data, live mining telemetry, or financial return modelling.

## Known failure modes

- Fewer than 2 rows or weights provided — minimum of 2 required
- operating_units value of 0 causes division error due to exclusiveMinimum constraint
- Row count and weight array length mismatch
- Values exceeding maximum bounds (1e16) rejected
- Non-numeric or missing required fields cause validation failure

## How this service works

Mining fleet spare coverage — Weighted result mean: Weighted result mean 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 weighted result mean report.

## Output

A bounded weighted result mean report containing the computed weighted average of the spare-unit-to-operating-unit coverage ratios across all supplied rows, weighted by the provided weight values. The report is scoped to user-supplied mining assumptions; no live prices or guaranteed returns are included.
