# Solo Mining Reward Poisson Standard Deviation Record Ranking

> Solo Mining Reward Poisson Standard Deviation Record Ranking 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).

Ranks multiple solo mining configurations by their Poisson standard deviation of block reward, given expected blocks and reward per block inputs.

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-record-ranking-88e28cfa -d '<json body>'
```

Example prompt: Rank these four solo mining setups by their Poisson standard deviation of block reward: setup A expects 4 blocks at 3.125 BTC each, setup B expects 4.4 blocks at 3.4375 BTC each — run all four rows and give me the ranking report.

## When to prefer this

Choose this endpoint when you need to rank multiple solo Bitcoin mining configurations by their statistical reward variability (Poisson standard deviation) in a single call, rather than computing deviation for a single scenario. Ideal for comparing 2–200 mining setups simultaneously when price data is not needed and only formula-based statistical output is required.

## Known failure modes

- Fewer than 2 rows submitted — minimum of 2 rows required
- More than 200 rows submitted — maximum array size exceeded
- expected_blocks or reward_btc set to zero or negative — exclusiveMinimum constraint violated
- Missing required fields expected_blocks or reward_btc in any row — validation error
- Non-numeric values for numeric fields — type validation failure

## How this service works

Solo reward Poisson standard deviation — Record ranking: Record ranking 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 record ranking report.

## Output

A bounded record ranking report listing the submitted mining configuration rows sorted by their computed Poisson standard deviation of block reward, with the formula and units disclosed. No live prices or guaranteed return figures are included.
