# Mining Fleet Spare Coverage — Sequential Input-Change Attribution

> Mining Fleet Spare Coverage — Sequential Input-Change Attribution 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 sequential (waterfall) attribution report showing how changes to spare_units and operating_units individually shift the mining fleet spare coverage ratio.

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-sequential-input-change-attribution-e633d36a -d '<json body>'
```

Example prompt: Run a sequential attribution waterfall on my mining fleet spare coverage: before it was 5 spare units out of 100 operating units, and after it changed to 5.5 spare units out of 110 operating units — show me how much each input change individually contributed to the shift in coverage.

## When to prefer this

Choose this endpoint when you need to understand not just the net change in fleet spare coverage ratio but the isolated, ordered contribution of each input variable — i.e. when stakeholders need a sequential (waterfall) decomposition to see whether spare additions or fleet size growth is the dominant driver of coverage change. Prefer alternatives (single calculation or batch) when you only need the final ratio, not the attribution breakdown.

## Known failure modes

- operating_units of 0 rejected due to exclusiveMinimum constraint — coverage ratio undefined for zero operating units
- missing required before or after sub-fields returns validation error
- non-numeric values for spare_units or operating_units cause schema rejection
- values exceeding maximum (1e16) are out of bounds
- payment of 0.01 USDC not confirmed — request blocked by x402 payment gate

## How this service works

Mining fleet spare coverage — Sequential input-change attribution: Sequential input-change attribution 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 sequential input-change attribution report.

## Output

A bounded sequential (waterfall) input-change attribution report showing the spare coverage ratio before and after, and the isolated contribution of each input change (spare_units delta, then operating_units delta) to the total coverage ratio shift, expressed using supplied assumptions and disclosed formula/units with no live pricing.
