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-two-input-4db516a8 -d '<json body>'
```

Example prompt: Can you run a solo mining reward Poisson standard deviation grid for me? Set the baseline to 4 expected_blocks and 3.125 BTC reward, sweep expected_blocks along the X axis at [3, 4, 5, 6] and reward_btc along the Y axis at [2.5, 3.125, 3.75].

## When to prefer this

Choose this endpoint when you need a structured two-variable sensitivity analysis of Poisson standard deviation for solo Bitcoin mining rewards — specifically when you want to see how reward variability shifts across a grid of expected_blocks and reward_btc combinations simultaneously, rather than a single-point calculation. Ideal for solo miners or analysts stress-testing assumptions without needing live price data.

## Known failure modes

- Invalid field_x/field_y enum values — must be 'expected_blocks' or 'reward_btc'
- baseline missing required fields (expected_blocks or reward_btc) returns validation error
- values_x or values_y arrays exceed 10 items — request rejected
- Zero or negative values for expected_blocks or reward_btc violate exclusiveMinimum constraint
- Payment failure (x402) prevents report generation

## How this service works

Solo reward Poisson standard deviation — Two-input scenario grid: Two-input scenario grid 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 two-input scenario grid report.

## Output

A bounded two-dimensional scenario grid report showing the Poisson standard deviation of solo Bitcoin mining rewards for each combination of the supplied X-axis and Y-axis values, computed from the provided baseline assumptions (expected_blocks and reward_btc). Outputs variability estimates per cell with formula and units disclosed; does not include live prices or guaranteed return figures.
