## 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-distribution-histogram-a34eda8c -d '<json body>'
```

Example prompt: Can you generate a Poisson standard deviation distribution histogram for solo Bitcoin mining, with 2 scenarios — one expecting 4 blocks at 3.125 BTC reward and one expecting 4.4 blocks at 3.4375 BTC reward — split into 10 bins?

## When to prefer this

Choose this endpoint when you need a Poisson-based statistical histogram of solo mining reward standard deviations given user-defined block expectations and BTC reward amounts. It is purpose-built for solo mining statistical modeling rather than pool mining, portfolio analysis, or live price feeds. Prefer it over general-purpose statistics tools when you need a ready-made, bounded histogram report with disclosed formula and units for a small number of mining scenarios (up to 200 rows).

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 items required in rows array
- bins value outside 1–30 range — validation error returned
- expected_blocks or reward_btc set to zero or negative — exclusiveMinimum constraint violated
- More than 200 row items submitted — maxItems limit exceeded
- Payment of 0.01 USDC not completed — 402 Payment Required response
- Malformed JSON body — 400 Bad Request

## How this service works

Solo reward Poisson standard deviation — Distribution histogram: Distribution histogram 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 histogram report.

## Output

Returns a bounded distribution histogram report showing Poisson standard deviation buckets for solo mining reward scenarios. The histogram breaks the reward deviation distribution into the specified number of bins, with frequency or probability values per bin, based on the supplied expected_blocks and reward_btc assumptions. Formula and units are disclosed in the response. No live price data or guaranteed returns are included.
