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-operating-cash-contribution-adjacent-period-changes-e469b625 -d '<json body>'
```

Example prompt: Can you calculate the adjacent period changes in my mining operating cash contribution? I have two periods: period 1 with revenue $100, electricity $60, maintenance $10, other $5, and period 2 with revenue $110, electricity $66, maintenance $11, other $5.50.

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.01 USDC) period-over-period delta report on mining operating cash contribution using supplied assumptions only. It is purpose-built for adjacent period comparison (not arbitrary period pairs or cumulative aggregation) and accepts up to 200 consecutive periods in a single call. Prefer it over general financial calculators when you specifically need mining cash margin changes broken down by electricity, maintenance, and other cost components.

## Known failure modes

- Fewer than 2 rows provided — minimum 2 periods required
- More than 200 rows submitted — exceeds maxItems limit
- revenue_usd set to 0 or negative — exclusiveMinimum constraint violation
- Non-numeric values in cost fields — schema validation error
- Payment not received or insufficient — x402 payment required before response

## How this service works

Mining operating cash contribution — Adjacent period changes: Adjacent period changes for Mining operating cash contribution. 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
