# Mining Difficulty Relative Change — Batch Calculation

> Mining Difficulty Relative Change — Batch Calculation 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).

Calculates the relative change between old and new mining difficulty values for up to 200 row pairs in a single batch request

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 mining-difficulty-relative-change-batch-calculation-7d2fcbf9 -d '<json body>'
```

Example prompt: Can you calculate the relative change in mining difficulty for these two periods: first period went from 100 to 110, and the second went from 110 to 121?

## When to prefer this

Choose this endpoint when you need to compute relative mining difficulty changes for multiple pairs of values in a single API call (up to 200 rows), paying only $0.01 USDC per batch. It is ideal for bulk epoch analysis, backtesting difficulty models, or feeding difficulty change metrics into larger mining profitability pipelines. Prefer it over single-row alternatives when processing more than one difficulty transition at a time for efficiency.

## Known failure modes

- Empty rows array (minItems:1 violated) returns validation error
- Rows array exceeding 200 items (maxItems:200) returns rejection
- Zero or negative difficulty values (exclusiveMinimum:0) cause validation failure
- Missing required new_difficulty or old_difficulty fields in any row returns schema error
- Payment of 0.01 USDC not included or fails causes 402 Payment Required
- Malformed JSON body returns 400 Bad Request

## How this service works

Mining difficulty relative change — Batch calculation: Batch calculation 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 batch calculation report.

## Output

A bounded batch calculation report containing the relative change (percentage or ratio) between the new and old mining difficulty for each row supplied, covering up to 200 input pairs. No live pricing, guaranteed returns, or live mining data is included — only the computed difficulty change values derived from the supplied inputs.
