## 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-adjacent-period-changes-b12a91d3 -d '<json body>'
```

Example prompt: Can you calculate the adjacent period changes in rejected share fraction for my last four mining periods? The data is: period 1 had 20 rejected out of 1000 total shares, period 2 had 22 rejected out of 1100 total, period 3 had 20 rejected out of 1000, and period 4 had 22 rejected out of 1100.

## When to prefer this

Choose this endpoint when you need a focused, per-period delta report on rejected share fraction specifically — i.e., you have a time-series of mining period data and want to understand how the ratio of rejected to total shares is shifting between consecutive periods. It is not a live data feed or a full mining profitability calculator; it is best suited for post-hoc analysis of mining log data or batch performance reviews using supplied assumptions.

## Known failure modes

- Fewer than 2 rows supplied — minItems constraint violated, request rejected
- rejected_shares exceeds total_shares for a row — logically invalid fraction
- total_shares set to 0 or negative — exclusiveMinimum constraint violated
- More than 200 rows submitted — maxItems constraint violated
- Non-numeric values in rejected_shares or total_shares fields — schema validation failure
- Missing required fields (rejected_shares or total_shares) in any row — validation error
- Payment of 0.01 USDC not included or declined — x402 payment required error

## How this service works

Rejected share fraction — Adjacent period changes: Adjacent period changes 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 adjacent period changes report.

## Output

Returns a bounded report of adjacent period changes for the rejected share fraction (rejected_shares / total_shares) across the submitted rows. Each adjacent pair of periods yields a computed delta or change value showing how the rejection fraction shifted, using the supplied mining data and disclosed formula. No live prices or guaranteed returns are included.
