## 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-distribution-summary-8ff31172 -d '<json body>'
```

Example prompt: Can you give me a distribution summary of the relative changes in mining difficulty for these pairs: old=100 new=110, old=110 new=121, old=95 new=100, old=100 new=105? I want to understand the spread of those adjustments.

## When to prefer this

Choose this endpoint when you need a compact statistical distribution summary of relative difficulty changes across multiple mining epochs or adjustment periods, and you have pairs of old/new difficulty values as inputs. It is purpose-built for mining difficulty analysis rather than general statistics or price-based mining return calculations.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 rows required
- More than 200 rows supplied — maximum 200 rows enforced
- new_difficulty or old_difficulty is zero or negative — must be exclusively greater than 0
- Missing required fields new_difficulty or old_difficulty in any row
- Payment failure or insufficient USDC balance
- Malformed input JSON causing schema validation error
