## 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 solo-mining-reward-poisson-standard-deviation-local-finite-change-5f654927 -d '<json body>'
```

Example prompt: Calculate the local finite-change elasticity of the solo mining reward Poisson standard deviation with respect to expected_blocks, using a baseline of 4 expected blocks and 3.125 BTC reward, with a 1% step.

## When to prefer this

Choose this endpoint when you need a precise, formula-backed local elasticity measure for the Poisson standard deviation of solo Bitcoin mining rewards with respect to a specific input assumption. It is ideal for sensitivity analysis on solo mining risk modeling where live price data is not needed and only the mathematical relationship between inputs and reward spread matters.

## Known failure modes

- Invalid field enum value (not 'expected_blocks' or 'reward_btc') returns validation error
- baseline values of zero or negative for expected_blocks or reward_btc are rejected (exclusiveMinimum: 0)
- step_percent outside range [0.01, 10] returns validation error
- Missing required baseline fields returns schema validation error
- Payment of 0.01 USDC not completed returns 402 Payment Required

## How this service works

Solo reward Poisson standard deviation — Local finite-change elasticity: Local finite-change elasticity for Solo reward Poisson standard deviation. 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 Poisson standard deviation of solo mining rewards, showing how sensitively the standard deviation responds to a small percentage change in the chosen input field (expected_blocks or reward_btc). The report includes the elasticity value, formula, and units, but no live prices or guaranteed return projections.
