# Mining Hardware Purchase Budget — Adjacent Period Changes

> Mining Hardware Purchase Budget — Adjacent Period Changes 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 adjacent period-over-period changes in mining hardware purchase budget totals (units, unit cost, shipping) from user-supplied assumptions, returning a bounded delta report.

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 mining-hardware-purchase-budget-adjacent-period-changes-c88dbccf -d '<json body>'
```

Example prompt: Can you calculate the adjacent period changes in my mining hardware purchase budget? I have two periods: period 1 is 10 units at $3,000 each with $1,000 shipping, and period 2 is 15 units at $3,200 each with $1,200 shipping.

## When to prefer this

Use this endpoint when you need a structured, period-over-period delta report specifically for mining hardware capital expenditure across 2–200 consecutive budget periods. It is purpose-built for mining fleet purchase planning with a fixed cost model, making it preferable over generic spreadsheet tools or broader financial APIs when the user only has unit count, unit price, and shipping as inputs and wants adjacent-period change analysis without live price feeds.

## Known failure modes

- Fewer than 2 rows supplied — minimum of 2 periods required
- Rows exceed 200-item maximum — request will be rejected
- Any row missing required fields (units, unit_usd, shipping_usd) — validation error
- Zero or negative unit/price values — exclusiveMinimum constraint violation
- Payment not processed or insufficient USDC balance — 402 response

## How this service works

Mining hardware purchase budget — Adjacent period changes: Adjacent period changes 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 adjacent period changes report.

## Output

A bounded report detailing the adjacent period-over-period changes for each consecutive pair of input rows, including deltas in total units, unit price, shipping cost, and derived totals — based solely on the user-supplied assumptions with no live market prices or guaranteed returns.
