# Solo Mining Reward Poisson Standard Deviation — Named Scenario Comparison

> Solo Mining Reward Poisson Standard Deviation — Named Scenario Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Computes and compares Poisson standard deviation of solo Bitcoin mining rewards across multiple named scenarios using user-supplied mining assumptions.

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-named-scenario-comparison-2cd31a89 -d '<json body>'
```

Example prompt: Compare the Poisson standard deviation of my solo mining reward across two scenarios: baseline is 3.125 BTC reward with 4 expected blocks, and an alternative called 'High Blocks' with 6.5 expected blocks — give me a named scenario comparison report.

## When to prefer this

Use this endpoint when you need to compare the statistical spread (Poisson standard deviation) of solo Bitcoin mining rewards across multiple explicitly named parameter scenarios in a single bounded call. Prefer this over single-calculation endpoints when you have 2–20 named hypothetical scenarios to evaluate side by side. Not suitable for live price data, pool mining calculations, or guaranteed return projections.

## Known failure modes

- Missing required baseline fields (reward_btc or expected_blocks) returns a validation error
- Scenarios array empty or missing label/overrides causes schema rejection
- Values of zero or negative for reward_btc or expected_blocks are rejected (exclusiveMinimum: 0)
- Scenarios array exceeding 20 items is rejected
- Payment not processed or insufficient USDC results in 402 response

## How this service works

Solo reward Poisson standard deviation — Named scenario comparison: Named scenario comparison 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 named scenario comparison report.

## Output

A bounded named scenario comparison report showing the Poisson standard deviation for solo mining reward under each submitted scenario versus the baseline, with the formula and units disclosed. Does not include live prices, actual mining data, or guaranteed return projections.
