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 asic-straight-line-daily-depreciation-adjacent-period-changes-f54672d0 -d '<json body>'
```

Example prompt: Calculate the adjacent period changes in straight-line daily depreciation for two ASIC miners: first one purchased for $3,000 with a $300 residual value over 900 days, and second purchased for $3,300 with a $330 residual over 990 days.

## When to prefer this

Choose this endpoint when you need period-over-period changes in straight-line daily depreciation specifically for ASIC mining hardware, using only asset cost, residual value, and life in days — no live price feeds, profitability estimates, or mining yield data needed. Ideal for accountants, fleet operators, or analysts doing depreciation reconciliation across adjacent reporting periods.

## Known failure modes

- Missing required fields (purchase_usd, residual_usd, life_days) returns validation error
- Fewer than 2 rows in the array returns a minimum items error
- life_days set to zero or negative triggers exclusiveMinimum violation
- Exceeding 200 rows in the array returns a maxItems error
- Non-numeric values for price or life fields cause schema type errors

## How this service works

ASIC straight-line daily depreciation — Adjacent period changes: Adjacent period changes for ASIC straight-line daily depreciation. 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 adjacent period changes in straight-line daily depreciation for each submitted row pair, including the computed daily depreciation amounts and the delta between consecutive periods, based solely on supplied purchase price, residual value, and useful life inputs.
