# Mining Difficulty Relative Change — Before and After Comparison

> Mining Difficulty Relative Change — 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 relative percentage change in mining difficulty across two scenario pairs (before and after), returning a side-by-side comparison report.

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-before-and-after-comparison-60301e2e -d '<json body>'
```

Example prompt: Can you compare the relative change in mining difficulty for two scenarios — before: old difficulty 100, new difficulty 110; and after: old difficulty 110, new difficulty 121 — and give me a side-by-side report?

## When to prefer this

Use this endpoint when you need to compare how mining difficulty percentage change evolved across two distinct adjustment windows — for example, before and after a halving, a hashrate surge, or a network event. It is ideal for mining economics analysis, scenario planning, and educational illustrations where no live price or guaranteed return data is needed, only the relative difficulty shift formula applied to two sets of supplied difficulty values.

## Known failure modes

- Zero or negative difficulty values rejected (exclusiveMinimum: 0 enforced)
- Values exceeding 10^16 maximum boundary rejected
- Missing required new_difficulty or old_difficulty fields in either scenario cause validation errors
- Payment failure (insufficient USDC) blocks report generation
- Malformed JSON body returns error response

## How this service works

Mining difficulty relative change — Before and after comparison: Before and after comparison 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 before and after comparison report.

## Output

A bounded comparison report containing the relative percentage change in mining difficulty for the 'before' scenario and the 'after' scenario, computed using the disclosed formula, presented side-by-side so the caller can see how much the difficulty adjustment grew or shrank between the two periods.
