## 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-simple-cash-payback-adjacent-period-changes-c92f1eb2 -d '<json body>'
```

Example prompt: Can you calculate the adjacent period changes in simple cash payback for my mining setup — I have two scenarios: first with a $3,000 investment and $10/day net, then a second with a $3,300 investment and $11/day net?

## When to prefer this

Use this endpoint when you need to understand how the simple cash payback period changes between adjacent mining configurations, such as when comparing sequential hardware upgrades, varying electricity costs reflected in net daily revenue, or modeling sensitivity of payback to input changes. Best suited for pre-investment analysis with user-supplied assumptions rather than live market data.

## Known failure modes

- Fewer than 2 rows supplied — minimum of 2 scenario rows required
- Net daily revenue or investment set to zero or negative — both must be strictly positive
- Array exceeds 200 items — maxItems limit enforced
- Non-numeric values in investment_usd or net_daily_usd fields cause validation failure
- Extremely large values near the maximum bound may produce unusually large payback periods

## How this service works

Mining simple cash payback — Adjacent period changes: Adjacent period changes for Mining simple cash payback. 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

Returns a bounded report showing the period-over-period (adjacent) changes in simple cash payback period for each consecutive pair of supplied mining scenarios, based on investment amount and net daily revenue. Includes computed deltas between adjacent rows using the simple payback formula (investment ÷ net daily), with units and formula disclosed. No live prices or guaranteed returns are included.
