# At-least-one Solo Block Probability — Rolling Mean Report

> At-least-one Solo Block Probability — Rolling Mean Report is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Computes a rolling mean of the at-least-one solo block probability for a series of mining scenarios defined by expected blocks per day and duration.

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 at-least-one-solo-block-probability-rolling-mean-report-7512f172 -d '<json body>'
```

Example prompt: Give me a rolling mean report for solo block probability across 4 scenarios: two entries with 100 days and 0.01 expected blocks per day, and two entries with 110 days and 0.011 expected blocks per day, using a rolling window of 2.

## When to prefer this

Choose this endpoint when you need a statistically smoothed view of solo block probability over a sequence of mining scenarios, rather than a single-point calculation. It is best when you have multiple time-period or hashrate scenarios and want a rolling average to reduce noise and observe trends in the probability of finding at least one block solo mining.

## Known failure modes

- Fewer than 2 rows supplied — minimum row count is 2
- Row missing required fields expected_blocks_per_day or days
- expected_blocks_per_day or days set to zero or negative — exclusive minimum enforced
- Window size less than 2 or greater than 200
- More than 200 rows supplied — maxItems exceeded
- Payment not included or insufficient — x402 payment required at $0.01 USDC

## How this service works

At-least-one solo block probability — Rolling mean report: Rolling mean report for At-least-one solo block probability. 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 rolling mean report report.

## Output

Returns a bounded rolling mean report showing the smoothed at-least-one solo block probability across the supplied mining scenario rows, including the formula used and units, with one report per API call. No live price data or guaranteed returns are included.
