# Mining Difficulty Relative Change — Record Ranking

> Mining Difficulty Relative Change — Record Ranking 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).

Accepts multiple pairs of old/new mining difficulty values and returns a ranked report of their relative percentage changes.

## 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-record-ranking-adfac1bb -d '<json body>'
```

Example prompt: I have four difficulty adjustment periods — old difficulties 100, 110, 95, and 120 with new difficulties 110, 121, 104.5, and 126 — can you rank them by relative change from largest to smallest?

## When to prefer this

Choose this endpoint when you need to rank multiple difficulty adjustment periods by their relative magnitude in a single call. It is ideal for batch comparison of 2–200 difficulty pairs when you want a sorted leaderboard-style output rather than a single before/after comparison. Prefer sibling endpoints for single-pair before/after comparisons or for availability fraction metrics.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 pairs required
- More than 200 rows supplied — exceeds maxItems limit
- Zero or negative difficulty values — exclusiveMinimum of 0 enforced
- Malformed row objects missing new_difficulty or old_difficulty fields
- Values exceeding 10^16 — maximum boundary violation
