## 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-base-100-rebase-report-8246b4f5 -d '<json body>'
```

Example prompt: I have a series of mining difficulty readings — old values 100, 110, 100, 110 and new values 110, 121, 110, 121 — can you rebase those relative changes to a base-100 index starting from row 0 and give me the index report?

## When to prefer this

Choose this endpoint when you need to convert raw paired difficulty readings (old and new) into a normalized base-100 index series to compare relative difficulty growth across periods, without needing live price data or profitability estimates. It is particularly useful for historical trend analysis, portfolio reporting, and research contexts where a clean indexed series is more meaningful than raw absolute difficulty numbers.

## Known failure modes

- Fewer than 2 rows supplied — minimum array size is 2
- new_difficulty or old_difficulty is zero or negative — exclusiveMinimum:0 enforced
- More than 200 rows submitted — maxItems:200 enforced
- base_index out of range — must be between 0 and 199 and within the length of the rows array
- Non-numeric difficulty values cause schema validation failure
- Payment failure or insufficient USDC balance blocks request

## How this service works

Mining difficulty relative change — Base-100 rebase report: Base-100 rebase 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 base-100 rebase report report.

## Output

Returns a base-100 rebased index series derived from the relative changes between each pair of new_difficulty and old_difficulty values in the input rows, anchored at the specified base_index row. The report discloses the formula and units used; no live prices, mining earnings, or guaranteed returns are included.
