Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-fleet-spare-coverage-local-finite-change-elasticity-bdf39a87 -d '<json body>'
```

Example prompt: Calculate the local finite-change elasticity of my mining fleet spare coverage, using a baseline of 5 spare units and 100 operating units, measuring sensitivity with respect to spare_units at a 1% step — I need the formula and units in the report.

## When to prefer this

Choose this endpoint when you need a precise, formula-disclosed local finite-change elasticity estimate for a mining fleet spare coverage ratio given known baseline assumptions, and want a bounded single-operation report at low cost ($0.01 USDC). Prefer this over generic sensitivity tools when you need mining-domain-specific framing with transparent formula and unit disclosure.

## Known failure modes

- operating_units set to zero (exclusiveMinimum violated) returns validation error
- step_percent outside [0.01, 10] range returns validation error
- spare_units or operating_units exceeding maximum (1e16) returns validation error
- invalid field enum value returns schema validation error
- missing required baseline properties returns error

## How this service works

Mining fleet spare coverage — Local finite-change elasticity: Local finite-change elasticity for Mining fleet spare coverage. 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 local finite-change elasticity report.

## Output

A bounded local finite-change elasticity report for the mining fleet spare coverage metric, including the computed elasticity coefficient, the formula used, and the units — based entirely on the user-supplied baseline assumptions. No live prices or guaranteed returns are included.
