# ASIC Straight-Line Daily Depreciation — Sequential Input-Change Attribution

> ASIC Straight-Line Daily Depreciation — 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 input-change attribution (waterfall) report for ASIC miner straight-line daily depreciation, showing how changes in purchase price, residual value, and useful life each shift the daily depreciation figure.

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-sequential-input-change-6cddfd1e -d '<json body>'
```

Example prompt: Run a sequential input-change attribution report for ASIC straight-line daily depreciation: before scenario is purchase $3,000, residual $300, life 900 days; after scenario is purchase $3,300, residual $330, life 990 days — show me how much each input change contributes to the shift in daily depreciation.

## When to prefer this

Choose this endpoint when you need to understand not just the difference in daily depreciation between two ASIC mining scenarios, but specifically which input change (cost, residual, or life) is responsible for how much of that difference — i.e., a waterfall/attribution breakdown rather than a simple delta. It is purpose-built for ASIC straight-line daily depreciation attribution, so prefer it over generic depreciation calculators when the sequential decomposition of input changes is the core requirement.

## Known failure modes

- life_days equal to zero triggers exclusiveMinimum validation error
- missing required fields (purchase_usd, residual_usd, life_days) in either before or after object returns validation error
- residual_usd exceeding purchase_usd may produce a negative depreciable base (edge case, formula-dependent)
- payment failure or insufficient USDC balance returns 402 Payment Required
- extremely large life_days values (approaching maximum) may produce near-zero daily depreciation figures that appear to be errors but are valid

## How this service works

ASIC straight-line daily depreciation — Sequential input-change attribution: Sequential input-change attribution 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 sequential input-change attribution report.

## Output

A bounded sequential input-change attribution report detailing: the before and after daily straight-line depreciation amounts for the ASIC miner, and the incremental contribution of each changed input (purchase price, residual value, useful life in days) to the total shift in daily depreciation, calculated in sequence.
