## 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-target-gap-calculator-98ae242c -d '<json body>'
```

Example prompt: Calculate the Poisson standard deviation target gap for solo Bitcoin mining, where the reward per block is 3.125 BTC, I expect to find 4 blocks, and my target is 100 BTC.

## When to prefer this

Choose this endpoint when you need a fast, low-cost statistical computation of the Poisson standard deviation target gap specifically for solo Bitcoin mining scenarios. It is ideal when you have known assumptions about block reward size and expected block count and want to quantify how far a revenue target sits from the expected reward distribution. Use it over general statistical APIs when you want a mining-domain-specific preset with formula and units already configured.

## Known failure modes

- Invalid or zero values for reward_btc or expected_blocks (must be positive non-zero numbers)
- Target value outside allowable bounds (±1e18)
- Malformed request body or missing required fields (reward_btc, expected_blocks)
- Payment failure or insufficient USDC balance for the $0.01 fee

## How this service works

Solo reward Poisson standard deviation — Target gap calculation: Target gap calculation 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 target gap calculation report.

## Output

A bounded target gap calculation report showing how far a specified target value is from the expected solo mining reward distribution, expressed in terms of Poisson standard deviation units, based on the supplied reward per block and expected block count. No live prices or guaranteed returns are provided.
