# At-least-one Solo Block Probability — Benchmark Correlation

> At-least-one Solo Block Probability — 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 2026-10-19).

Computes and correlates the probability of finding at least one solo block across varying mining assumptions against a set of benchmark thresholds.

## 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-benchmark-correlation-a394fc35 -d '<json body>'
```

Example prompt: What's the correlation between my at-least-one solo block probability and benchmarks of 10, 20, 30, and 40, given I expect 0.01 blocks per day over 100 days and 0.011 blocks per day over 110 days?

## When to prefer this

Choose this endpoint when you need a statistical correlation between computed solo block probabilities and a set of reference benchmarks across multiple mining assumption scenarios. It is purpose-built for solo mining probability analysis with multi-row, multi-benchmark comparison, making it ideal when you want to evaluate sensitivity of block-finding odds to changes in hashrate or duration relative to known reference points — not for pool mining, live price data, or portfolio analysis.

## Known failure modes

- rows array has fewer than 2 items — returns validation error
- expected_blocks_per_day or days set to 0 or negative — fails exclusiveMinimum validation
- benchmarks array has fewer than 2 entries — returns validation error
- rows or benchmarks exceed 200 items — returns maxItems validation error
- Malformed JSON body — returns 400 bad request
- Payment not provided or insufficient — returns 402 Payment Required

## How this service works

At-least-one solo block probability — Benchmark correlation: Benchmark correlation 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 benchmark correlation report.

## Output

Returns a bounded benchmark correlation report showing the at-least-one solo block probability for each input row (expected_blocks_per_day × days combination) and how those probabilities correlate against the provided benchmark values. Output includes formula-derived probability figures and correlation metrics; no live prices or guaranteed return projections.
