## 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-two-input-scenario-grid-5dc89b65 -d '<json body>'
```

Example prompt: Run a two-input payback scenario grid for my mining setup — baseline investment is $3,000 and net daily profit is $10. Vary investment across $2,500, $3,000, $3,500, and $4,000, and vary net daily profit across $8, $10, $12, and $15, so I can see how long it takes to break even across all those combinations.

## When to prefer this

Use this endpoint when you need a quick, pre-built two-axis sensitivity table for mining simple cash payback — specifically when you want to see how payback days change across a matrix of investment cost and net daily profit values. Prefer this over a single-calculation endpoint when you need to compare multiple scenarios simultaneously without issuing separate requests. It is purpose-built for mining assumptions (no live price feeds), so choose it when your inputs are static estimates rather than real-time market data.

## Known failure modes

- Invalid field_x/field_y values (must be 'investment_usd' or 'net_daily_usd')
- values_x or values_y arrays exceed 10 items (maxItems constraint)
- baseline missing required fields investment_usd or net_daily_usd
- Zero or negative values where exclusiveMinimum:0 applies
- Payment failure or insufficient USDC balance for x402 micropayment
- field_x and field_y set to the same variable, producing a degenerate grid

## How this service works

Mining simple cash payback — Two-input scenario grid: Two-input scenario grid 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 two-input scenario grid report.

## Output

A bounded two-input scenario grid report showing the simple cash payback period (in days) for each combination of the chosen x-axis and y-axis variable values (investment_usd and net_daily_usd). Results are computed from supplied assumptions only, with no live prices or guaranteed returns.
