# Solo Mining Reward Poisson Standard Deviation — Benchmark Correlation

> Solo Mining Reward Poisson Standard Deviation — Benchmark Correlation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Computes the Poisson standard deviation of solo mining rewards across multiple scenarios and correlates each against a set of benchmark values.

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-benchmark-correlation-da2302e9 -d '<json body>'
```

Example prompt: Can you compute the Poisson standard deviation for these two solo mining scenarios — one with 4 expected blocks at 3.125 BTC reward and another with 4.4 expected blocks at 3.4375 BTC reward — and correlate the deviations against benchmarks of 10, 20, 30, and 40?

## When to prefer this

Choose this endpoint when you need a statistically grounded Poisson standard deviation computed for solo Bitcoin mining reward scenarios and want those deviations explicitly correlated against a set of numeric benchmark values in a single bounded report. It is ideal when you have multiple scenario rows to compare simultaneously (up to 200) and need a formula-transparent, unit-disclosed output without live market data dependencies.

## Known failure modes

- Fewer than 2 rows or 2 benchmark values provided — minimum array length not met
- expected_blocks or reward_btc set to 0 or negative — exclusiveMinimum constraint violated
- Arrays exceed 200 items — maxItems constraint violated
- reward_btc or expected_blocks set to extremely large values causing numerical instability
- Missing required fields (expected_blocks or reward_btc) in any row object
- Payment of 0.01 USDC not processed — 402 payment required error

## How this service works

Solo reward Poisson standard deviation — Benchmark correlation: Benchmark correlation 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 benchmark correlation report.

## Output

Returns a bounded benchmark correlation report showing the Poisson standard deviation for each supplied mining scenario row (defined by expected_blocks and reward_btc) correlated against each of the provided benchmark values. The report uses the supplied inputs only, with formula and units disclosed; no live prices or return guarantees are included.
