# Mining Hardware Purchase Budget — Local Finite-Change Elasticity

> Mining Hardware Purchase Budget — 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 2026-10-15).

Computes the local finite-change elasticity of a mining hardware purchase budget with respect to a specified input field (units, unit price, or shipping cost) given a baseline scenario and a step size.

## 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-hardware-purchase-budget-local-finite-change-elasticity-d74ad380 -d '<json body>'
```

Example prompt: Calculate the local finite-change elasticity of my mining hardware purchase budget with respect to unit price, using a baseline of 10 units at $3,000 each with $1,000 shipping, and a step size of 1%.

## When to prefer this

Choose this endpoint when you need a precise, single-field local elasticity calculation for a mining hardware purchase budget using your own cost assumptions. It is ideal for sensitivity analysis during capital expenditure planning for crypto mining fleets when you want to understand how a marginal percentage change in one cost driver (unit count, unit price, or shipping) affects the total budget. Not suitable for live price lookups, multi-variable simultaneous sensitivity, or guaranteed ROI projections.

## Known failure modes

- Invalid field enum value returns validation error
- Step percent outside 0.01–10 range is rejected
- Zero or negative values for units or unit_usd trigger exclusiveMinimum validation error
- Missing required baseline fields returns schema error
- Payment failure (insufficient USDC) results in 402 response

## How this service works

Mining hardware purchase budget — Local finite-change elasticity: Local finite-change elasticity for Mining hardware purchase budget. 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

Returns a bounded local finite-change elasticity report showing how the total mining hardware purchase budget changes in response to a small proportional change in the selected input field (units, unit price, or shipping cost), expressed as an elasticity coefficient with formula and units disclosed. No live prices or guaranteed returns are included.
