# Mining Hardware Purchase Budget — Sequential Input-Change Attribution

> Mining Hardware Purchase Budget — 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 (waterfall) attribution report showing how each individual input change—units, unit price, shipping—contributes to the total delta in a mining hardware purchase budget.

## 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-sequential-input-change-attribution-1f752ae6 -d '<json body>'
```

Example prompt: Run a sequential input-change attribution waterfall for my mining hardware purchase: the before scenario is 10 units at $3,000 each with $1,000 shipping, and the after scenario is 11 units at $3,300 each with $1,100 shipping — show me how each change contributed to the total budget delta.

## When to prefer this

Choose this endpoint when you need to understand exactly how each individual input change (unit count, per-unit price, shipping) sequentially contributed to a shift in total mining hardware purchase budget — particularly useful for variance analysis, vendor negotiations, or financial reporting where a waterfall decomposition is required. Prefer this over generic budget calculators when the specific sequential (order-dependent) attribution methodology matters.

## Known failure modes

- Invalid schema: missing required fields (units, unit_usd, or shipping_usd) returns a validation error
- Zero or negative units rejected due to exclusiveMinimum constraint
- Extremely large values (up to 1e16) accepted but may produce large numeric outputs
- Payment failure: insufficient USDC balance or x402 protocol error prevents report generation
- Identical before/after inputs produce a zero-delta attribution report

## How this service works

Mining hardware purchase budget — Sequential input-change attribution: Sequential input-change attribution 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 sequential input-change attribution report.

## Output

A bounded sequential input-change attribution report that shows, for each input variable (units, unit price, shipping), the incremental contribution to the total change in mining hardware purchase budget — presented as a waterfall decomposition with units and formulas disclosed. No live prices or guaranteed returns are included.
