## 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 mining-difficulty-relative-change-rolling-mean-report-6e9f8a25 -d '<json body>'
```

Example prompt: Can you calculate the rolling mean of mining difficulty relative changes for these 4 data points — (old: 100, new: 110), (old: 110, new: 121), (old: 100, new: 110), (old: 110, new: 121) — using a window size of 2?

## When to prefer this

Choose this endpoint when you need a statistical rolling mean specifically computed over mining difficulty relative changes, using a configurable window size across a series of old/new difficulty pairs. Ideal for smoothing noisy epoch-to-epoch difficulty adjustments, identifying trends, or feeding aggregated difficulty signals into mining strategy models. This endpoint is pre-configured as a specialized preset for this exact computation and is not a general-purpose statistics API.

## Known failure modes

- Fewer than 2 rows submitted — minimum of 2 rows required
- Window size exceeds number of submitted rows — computation not possible
- new_difficulty or old_difficulty values are zero or negative — exclusiveMinimum violation
- More than 200 rows submitted — exceeds maxItems limit
- Window size outside 2–200 range — schema validation failure
- Missing required fields new_difficulty or old_difficulty in any row

## How this service works

Mining difficulty relative change — Rolling mean report: Rolling mean report for Mining difficulty relative change. 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 rolling mean report of the mining difficulty relative change values computed across the submitted rows using the specified window size. The output is bounded statistical summary data including the smoothed mean values per window, based solely on the supplied difficulty figures. No live pricing or profitability guarantees are included.
