# Mining Simple Cash Payback — Sequential Input-Change Attribution

> Mining Simple Cash Payback — 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 2026-10-16).

Computes a sequential (waterfall) attribution of how changes in mining investment and net daily revenue inputs affect the simple cash payback period.

## 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-simple-cash-payback-sequential-input-change-attribution-0d6626e2 -d '<json body>'
```

Example prompt: Run a sequential input-change attribution on my mining simple payback: before the upgrade my hardware cost was $3,000 and net daily revenue was $10, and after the upgrade hardware cost is $3,300 and net daily revenue is $11 — show me which change drove the payback period shift more.

## When to prefer this

Choose this endpoint when you need to understand not just the new payback period, but how much each changed input (hardware investment vs daily net revenue) contributed to the shift — a waterfall/sequential attribution breakdown. Prefer this over a simple before-and-after comparison when you want to isolate and quantify the marginal effect of each input change separately.

## Known failure modes

- net_daily_usd or investment_usd of 0 or negative triggers validation error (exclusiveMinimum:0)
- missing required fields (investment_usd or net_daily_usd) in before or after objects returns error
- extremely large values may hit floating-point precision limits
- payment failure or insufficient USDC balance blocks request
- malformed JSON body returns 400-level error

## How this service works

Mining simple cash payback — Sequential input-change attribution: Sequential input-change attribution for Mining simple cash payback. 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 decomposes the shift in simple cash payback period (investment_usd / net_daily_usd) into the contribution from the change in investment and the contribution from the change in net daily revenue, using the supplied before and after assumptions. No live prices or guaranteed returns are included.
