# Mining Operating Cash Reserve — Local Finite-Change Elasticity

> Mining Operating Cash Reserve — Local Finite-Change Elasticity is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Computes the local finite-change elasticity of a mining operation's cash reserve with respect to a chosen input variable (daily cost or reserve days), given user-supplied baseline 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-operating-cash-reserve-local-finite-change-elasticity-19b22053 -d '<json body>'
```

Example prompt: Run a local finite-change elasticity report on my mining cash reserve using a baseline of 30 reserve days and $150 daily cost, perturbing the daily_cost_usd field by 1%.

## When to prefer this

Choose this endpoint when you need a precise, formula-disclosed local sensitivity (elasticity) metric for a mining operation's cash reserve at a specific baseline, and you only have static mining assumptions (no live price feeds needed). It is especially useful for budget stress-testing, cost sensitivity analysis, and operational planning where a bounded single-variable perturbation report suffices.

## Known failure modes

- Invalid or out-of-range baseline values (e.g. zero or negative daily_cost_usd or reserve_days) return a validation error
- step_percent outside [0.01, 10] range is rejected
- Missing required baseline fields causes a schema validation error
- Payment failure or insufficient USDC results in a 402 Payment Required response
- Unsupported field enum value returns an error

## How this service works

Mining operating cash reserve — Local finite-change elasticity: Local finite-change elasticity for Mining operating cash reserve. 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 cash reserve metric, showing the elasticity value of the selected field (daily_cost_usd or reserve_days) at the supplied baseline, along with the formula and units used. No live prices or guaranteed returns are included.
