## 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-operating-cash-reserve-adjacent-period-changes-a3a2fae3 -d '<json body>'
```

Example prompt: I have two mining periods I want to compare: first period has 30 reserve days at $100/day, and the second has 33 reserve days at $110/day — can you calculate the adjacent period changes in my mining operating cash reserve?

## When to prefer this

Use this endpoint when you need to quantify how a mining operation's cash reserve changes between consecutive periods based on static cost assumptions. Ideal for scenario modeling where daily costs and reserve days vary across periods and you want a structured adjacent-period delta report. Not suitable for live price feeds, real-time mining profitability, or non-mining financial calculations.

## Known failure modes

- Fewer than 2 rows provided — minimum 2 rows required for period comparison
- More than 200 rows submitted — exceeds maxItems limit
- daily_cost_usd or reserve_days set to zero or negative — exclusiveMinimum of 0 enforced
- Missing required fields daily_cost_usd or reserve_days in any row
- Values exceeding the maximum threshold cause validation rejection

## How this service works

Mining operating cash reserve — Adjacent period changes: Adjacent period changes for Mining operating cash reserve. 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 adjacent period changes report.

## Output

A bounded report showing the adjacent period changes in mining operating cash reserve for each consecutive pair of input rows, including computed deltas based on supplied daily cost and reserve days assumptions. No live prices or guaranteed returns are included.
