## 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-operating-contribution-margin-target-gap-calculator-a27349b6 -d '<json body>'
```

Example prompt: My mining operation has revenue of $500,000 and a contribution of $120,000 — can you calculate the gap between the current contribution margin and my target of $175,000?

## When to prefer this

Use this endpoint when you need a quick, structured target-gap calculation for a mining operation's contribution margin, given your own revenue and contribution assumptions, and want a bounded report without live market data dependencies. Prefer it over generic spreadsheet calculations when you need a standardised, auditable output per operation within a shared multi-profile mining engine.

## Known failure modes

- Revenue value of zero or below causes validation error (revenue_usd must be > 0)
- Contribution value outside allowed range (-1,000,000,000 to 10,000,000,000,000,000) causes schema rejection
- Target value outside allowed range causes validation failure
- Missing required fields (revenue_usd or contribution_usd) returns error
- Payment failure (insufficient USDC balance) blocks request
