# Mining Fleet Spare Coverage Index — Base-100 Rebase Report

> Mining Fleet Spare Coverage Index — Base-100 Rebase Report 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 Base-100 rebased index of mining fleet spare coverage ratios across up to 200 time periods or scenarios, anchored to a user-selected base observation.

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-index-base-100-rebase-report-412dd420 -d '<json body>'
```

Example prompt: I have 8 periods of mining fleet data — can you compute a Base-100 spare coverage index rebased to period 0, using spare unit counts of [5, 6, 4, 7, 5, 6, 5, 8] against operating unit counts of [100, 110, 95, 120, 100, 115, 105, 130]?

## When to prefer this

Choose this endpoint when you need a normalized, Base-100 rebased view of mining fleet spare coverage ratios across multiple time periods or scenarios. It is purpose-built for mining operational analytics with supplied assumptions, not for live pricing or financial forecasting. Prefer it over generic index calculators when your domain is mining fleet management and you need a ready-made preset engine that handles up to 200 observation rows at minimal cost.

## Known failure modes

- Fewer than 2 rows provided — minItems:2 constraint violated, request rejected
- operating_units set to 0 — exclusiveMinimum:0 means zero is not allowed, causing validation failure
- base_index out of range — must be between 0 and (number of rows minus 1), else error
- More than 200 rows submitted — maxItems:200 exceeded, request rejected
- Payment failure — 0.01 USDC x402 payment not processed, endpoint returns 402

## How this service works

Mining fleet spare coverage — Base-100 rebase report: Base-100 rebase report 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 base-100 rebase report report.

## Output

Returns a Base-100 rebased index series where each row's spare coverage ratio (spare_units / operating_units) is expressed relative to the chosen base row (set to 100). The report includes the normalized index value for each input row, allowing direct comparison of spare coverage across periods or scenarios without raw unit distortion. No live prices or guaranteed returns are included.
