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-bitcoin-mining-reward-poisson-standard-deviation-summary-636e506c -d '<json body>'
```

Example prompt: Give me a Poisson standard deviation distribution summary for two solo mining scenarios: one with 4 expected blocks at 3.125 BTC reward each, and another with 4.4 expected blocks at 3.4375 BTC reward each.

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.01 USDC) Poisson statistical summary of solo Bitcoin mining reward variance based on user-supplied block expectations and reward sizes, without needing live price feeds or real-time mining data. Ideal for batch comparison of multiple mining scenarios (up to 200 rows) in a single call.

## Known failure modes

- Input array has fewer than 2 rows — minimum 2 rows required
- expected_blocks or reward_btc set to zero or negative — exclusiveMinimum of 0 enforced
- Array exceeds 200 rows — maxItems limit exceeded
- Missing required fields expected_blocks or reward_btc in any row
- Non-numeric values passed for numeric fields

## How this service works

Solo reward Poisson standard deviation — Distribution summary: Distribution summary 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 distribution summary report.

## Output

A bounded distribution summary report containing the Poisson standard deviation for each input row of expected blocks and reward values, along with the formula and units used. No live prices or guaranteed return figures are included.
