# Mining Simple Cash Payback — Weighted Result Mean

> Mining Simple Cash Payback — Weighted Result Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Computes a weighted mean of simple cash payback periods across multiple mining investment scenarios using user-supplied assumptions.

## 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-weighted-result-mean-291f6916 -d '<json body>'
```

Example prompt: I have four mining rigs — two cost $3,000 each earning $10/day net, and two cost $3,300 each earning $11/day net. Give me the weighted mean simple cash payback period using weights of 1, 2, 1, 2 respectively.

## When to prefer this

Choose this endpoint when you need a single weighted aggregate payback metric across multiple distinct mining scenarios, rather than individual payback values per scenario. It is ideal when different rigs or configurations should contribute unequally to the summary result (e.g., reflecting fleet composition). If you need individual per-row payback figures or a simple unweighted mean, use the corresponding batch or single-calculation endpoints instead.

## Known failure modes

- Fewer than 2 rows provided — minimum 2 rows required
- More than 200 rows provided — maximum is 200
- investment_usd or net_daily_usd set to 0 or negative — both must be strictly positive
- Weights array length does not match rows array length — arrays must be the same size
- net_daily_usd exceeds maximum allowed value
- Malformed JSON body — returns 400 error
- Payment not included or insufficient — returns 402 Payment Required

## How this service works

Mining simple cash payback — Weighted result mean: Weighted result mean 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 weighted result mean report.

## Output

A bounded weighted result mean report containing the weighted average simple cash payback period (in days) computed from the supplied investment amounts, net daily earnings, and per-row weights. No live prices or guaranteed returns are included — results are based entirely on the user-supplied assumptions.
