## 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-before-and-after-comparison-33f21cc3 -d '<json body>'
```

Example prompt: Compare the simple cash payback period for my mining setup: before the upgrade I invested $3,000 and net $10/day, and after the upgrade I'll invest $3,300 and net $11/day — how does the payback period change?

## When to prefer this

Choose this endpoint when you need a structured, side-by-side simple cash payback comparison for exactly two mining scenarios (before and after a change). It is ideal for evaluating the impact of a hardware upgrade, energy cost change, or revenue adjustment on capital recovery time. It is not suitable for multi-scenario sweeps, live price lookups, or complex ROI models — it uses only supplied assumptions with disclosed formula.

## Known failure modes

- net_daily_usd of 0 or negative will be rejected (exclusiveMinimum:0 enforced)
- investment_usd of 0 or negative will be rejected (exclusiveMinimum:0 enforced)
- missing required fields (investment_usd or net_daily_usd in either before or after object) returns a validation error
- values exceeding 1e16 will be rejected by schema
- payment of less than 0.01 USDC will result in a 402 Payment Required response

## How this service works

Mining simple cash payback — Before and after comparison: Before and after comparison 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 before and after comparison report.

## Output

A bounded before-and-after comparison report showing the simple cash payback period (investment divided by net daily income) for both the 'before' and 'after' mining scenarios, along with the formula and units used, so you can see exactly how the payback period changes between the two configurations.
