# ASIC Straight-Line Daily Depreciation — Local Finite-Change Elasticity

> ASIC Straight-Line Daily Depreciation — Local Finite-Change Elasticity is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).

Computes the local finite-change elasticity of ASIC straight-line daily depreciation with respect to a chosen input parameter (purchase price, residual value, or asset life).

## 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-local-finite-change-elasticity-98b43c17 -d '<json body>'
```

Example prompt: What's the local finite-change elasticity of daily straight-line ASIC depreciation with respect to purchase price, assuming I bought the miner for $3,000, expect a $300 residual value, and plan to use it for 900 days — use a 1% step?

## When to prefer this

Choose this endpoint when you need a precise, formula-based sensitivity metric (finite-change elasticity) for ASIC hardware depreciation under the straight-line method, and you already have your own purchase cost, residual value, and useful life assumptions. Prefer it over generic depreciation calculators when you specifically need to understand how much the daily depreciation rate changes in response to a small percentage perturbation in one input.

## Known failure modes

- Invalid field enum value — must be one of purchase_usd, residual_usd, life_days
- life_days must be strictly greater than 0 (exclusiveMinimum)
- purchase_usd must be strictly greater than 0 (exclusiveMinimum)
- step_percent out of range — must be between 0.01 and 10
- Payment failure — 0.01 USDC not processed via x402 protocol
- Baseline object missing required fields (purchase_usd, residual_usd, life_days)

## How this service works

ASIC straight-line daily depreciation — Local finite-change elasticity: Local finite-change elasticity 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 local finite-change elasticity report.

## Output

A bounded local finite-change elasticity report showing how the ASIC's straight-line daily depreciation value responds to a small percentage change in the selected input field (purchase price, residual value, or asset life), computed using the supplied baseline assumptions and step size. No live pricing or return guarantees are included.
