# Solo Reward Poisson Standard Deviation — Base-100 Rebase Report

> Solo Reward Poisson Standard Deviation — Base-100 Rebase Report 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 a Base-100 rebased Poisson standard deviation index for solo Bitcoin mining reward scenarios given expected block counts and per-block rewards.

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-reward-poisson-standard-deviation-base-100-rebase-report-0a242988 -d '<json body>'
```

Example prompt: Give me a Base-100 rebased Poisson standard deviation report for two solo mining scenarios: one with 4 expected blocks at 3.125 BTC reward and one with 4.4 expected blocks at 3.4375 BTC reward, using the first scenario as the base index.

## When to prefer this

Choose this endpoint when you need a statistically rigorous, normalized view of solo mining reward variability using a Poisson model, particularly when comparing multiple mining scenarios on a common Base-100 scale. It is ideal for agents building mining risk dashboards, comparing hashrate tiers, or evaluating how halving events affect reward spread — without needing live price feeds or external data sources.

## Known failure modes

- rows array contains fewer than 2 items — minimum 2 rows required
- base_index out of range — must be between 0 and number of rows minus 1
- expected_blocks or reward_btc set to zero or negative — exclusiveMinimum enforced
- rows array exceeds 200 items — maxItems limit
- Invalid numeric types for expected_blocks or reward_btc — schema validation error
- Payment of 0.01 USDC not fulfilled — x402 payment required error

## How this service works

Solo reward Poisson standard deviation — Base-100 rebase report: Base-100 rebase report 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 base-100 rebase report report.

## Output

Returns a Base-100 rebased report of the Poisson standard deviation for each input row of mining assumptions. Each row's deviation is normalized relative to the designated base index row, giving a comparative index of reward variability across scenarios. No live pricing or guaranteed return figures are included — only formula-derived statistical outputs based on the supplied expected_blocks and reward_btc values.
