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 solo-mining-reward-poisson-standard-deviation-calculator-dae1e004 -d '<json body>'
```

Example prompt: Calculate the Poisson standard deviation for solo Bitcoin mining with a block reward of 3.125 BTC and 4 expected blocks found.

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.01 USDC) single-shot Poisson standard deviation calculation for solo Bitcoin mining reward variance, using only your own assumed inputs (block reward and expected block count). It is not suitable for real-time price lookups, pool mining scenarios, or guaranteed return projections.

## Known failure modes

- Invalid or non-positive reward_btc value returns a validation error
- Invalid or non-positive expected_blocks value returns a validation error
- Missing required fields (reward_btc or expected_blocks) causes a schema rejection
- Extremely large values near the upper bound may produce precision edge cases
- Payment failure or insufficient USDC balance prevents call execution

## How this service works

Solo reward Poisson standard deviation — Single calculation: Single 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 single calculation report.

## Output

Returns a single bounded calculation report containing the Poisson standard deviation of solo mining rewards, derived from the supplied block reward in BTC and the expected number of blocks. No live price data or guaranteed returns are included; the formula and units are disclosed in the response.
