# Rejected Share Fraction Before-and-After Comparison

> Rejected Share Fraction Before-and-After Comparison 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 and compares the rejected share fraction metric for cryptocurrency mining operations between two time periods (before and after).

## 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-before-and-after-comparison-a6e84d99 -d '<json body>'
```

Example prompt: Compare my mining pool's rejected share fraction: before I had 1000 total shares with 20 rejected, and after the hardware change I now have 1100 total shares with 22 rejected — give me a before-and-after report.

## When to prefer this

Choose this endpoint when you need a quick, inexpensive ($0.01 USDC) computation of rejected share fraction for two distinct mining snapshots and want a structured before-and-after comparison report. It is ideal for evaluating the impact of hardware changes, pool reconfigurations, firmware upgrades, or other operational changes on mining share rejection rates. Prefer it over manual calculation when you want a consistent, formula-disclosed report format for a single comparison pair.

## Known failure modes

- total_shares of 0 or missing will cause a division-by-zero or validation error
- rejected_shares exceeding total_shares may produce a fraction greater than 1, which is logically invalid
- missing required fields (total_shares or rejected_shares) in either before or after object will cause a schema validation failure
- extremely large share counts near the maximum boundary may introduce floating-point precision issues

## How this service works

Rejected share fraction — Before and after comparison: Before and after comparison 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 before and after comparison report.

## Output

A bounded before-and-after comparison report showing the rejected share fraction (rejected_shares / total_shares) for both the 'before' and 'after' periods, along with a comparison of the two values. No live prices, actual mining results, or guaranteed returns are included — only the computed metric based on the supplied share counts.
