# Rejected Share Fraction — Weighted Result Mean

> Rejected Share Fraction — Weighted Result Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Computes a weighted mean of rejected share fraction across multiple mining data rows, using user-supplied weights.

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 rejected-share-fraction-weighted-result-mean-bab223e0 -d '<json body>'
```

Example prompt: Calculate the weighted mean rejected share fraction for these 4 mining periods: {total_shares: 1000, rejected_shares: 20}, {total_shares: 1100, rejected_shares: 22}, {total_shares: 1000, rejected_shares: 20}, {total_shares: 1100, rejected_shares: 22}, using weights 1, 2, 1, 2 — I want the single weighted average rejection rate.

## When to prefer this

Use this endpoint when you need a statistically weighted aggregate of rejected share fraction across multiple mining sessions, workers, or time periods and want a single bounded mean value. Prefer this over a simple arithmetic mean when different rows should carry different importance (e.g. larger hash sessions deserve more weight). This is a specialized mining analytics computation — not suitable for live price lookups or profitability forecasting.

## Known failure modes

- Fewer than 2 rows provided — minimum 2 items required
- More than 200 rows provided — maxItems limit exceeded
- weights array length does not match rows array length
- rejected_shares exceeds total_shares for a given row (logically invalid but may still compute)
- total_shares is zero or negative — exclusiveMinimum constraint violated
- Non-numeric values in rows or weights arrays

## How this service works

Rejected share fraction — Weighted result mean: Weighted result mean for Rejected share fraction. 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 weighted result mean report.

## Output

Returns a single bounded weighted result mean report for the rejected share fraction metric, computed from the supplied rows of rejected_shares and total_shares values combined with the given weights. No live pricing or guaranteed return data is included — purely a statistical aggregate based on mining assumptions provided.
